Electrical Noise Can Damage Your Electronic Equipment

Did you know that many of the electronic devices that fill our homes, businesses and factories generate "noise"? The hum of fluorescent lighting or the constant static from the radio in your garage are shining examples of electronic noise. Most folks have become accustomed to these inconveniences but their presence may indicate a more serious problem in a home electrical system.

If you have ever noticed hissing from your stereo speakers or humming from your lamps or appliances it is likely you are listening to the results of harmonic interference. This noise creates stress on your devices leading to the production of heat which in turn increases energy usage. The power you are buying from your electric company is simply not being used efficiently. Heat is the enemy of all electronic devices so the lack of noise filtration can be responsible for reduced life or outright premature failure of your valuable electronic equipment.

Items such as personal computers and mobile phone chargers are additional examples. Rather than drawing current at a steady rate, such as a ceiling fan, they use a "switched-mode power supply". This means the power is sliced up into very small pieces as it's needed by the power supply. As this happens, a portion of the current drawn is actually unused and stays in the power line as very small spikes of power that cannot be utilized by the device. The power is essentially wasted and converts to heat. These switched-mode power supplies are useful for being able to utilize a wide range of incoming current efficiently but they result in the heating of components because of the wasted power that they produce.

While there are individual devices available that will mitigate the destructive forces of harmonic interference alone, the most useful of these devices is a unit that provides energy savings and surge protection in addition to the reduction of harmonic interference. Installing such a device will generally reduce energy costs from 5% - 15% for the average homeowner. The unit has a usable life of 20 years and will pay for itself in 24 - 36 months. That means your savings after that point goes right in your pocket. In addition, increasing the life of electrical motors through heat reduction can yield real money by lowering the replacement costs of valuable electronics.

Marine Electronics

Marine radar (Radio Detection and Ranging) is used to detect objects and their position relative to your location. It works by sending out a radio signal. When the signal hits an object it is reflected back to the radar unit which can then calculate the bearing of the object.

A marine radar device is an essential navigation aid for boaters. It is useful for detecting boats, birds landmasses, and weather systems even when visibility conditions are less than favorable.

Marine Radar: Top Features to Look For
The two most important features of any marine radar device are the transmitter power and the beam angle. Power can range from 2 to 4 Kilowatts. The higher the power, the better your transmitter can see through fog and rain and the further the signal can reach. Power is a factor in how well your radar does in bad weather. Blinding rain can cause low power marine radar to be less than effective.

Beam angle is determined by the size of your marine radar's antenna. A long antenna will produce a narrow beam that gives good discrimination between objects close together. A short antenna has a wider beam angle allowing the radar to scan a wider area at one time. Antennas are often customizable or configurable and can be purchased separately.

Guard Zone Alarm
Most marine radars allow you to set a guard zone around your boat. You specify the safety distance and set an alarm. If your vessel detects a buoy, landmass or other obstacle within the proximity of your guard zone, the alarm sounds.

Split Screen Displays
Split screen displays allow you to monitor objects close to your boat and objects further away at the same time. This feature is useful, among other things, for navigating buoys as you leave the shoreline while heading out towards a more distant spot.

Best Use of Marine Radar
One of the best features of marine radar is its ability to determine where you are with respect to where you were a few minutes ago. This "echo trail" feature can be used to determine how well you are navigating an obstacle as well as how well you maintaining the bearing you have set for your vessel. The echo trail is displayed on the radar's display screen so you can quickly assess visually what is going on.

Integrated Marine Radar and GPS/Chartplotters
Marine radars are fairly expensive; many units run in the thousands of dollars. It is a good idea to talk with other boaters and see what they are using and what features they like before committing that much money. To get more bang for the buck, look for marine radars that are already incorporated into other marine electronics such as GPS units and Chartplotters. Integrating your marine components reduces the complexity of your visual displays and reduces overall cost of items. Even though sometimes you have to compromise with the features of each component offered in the integrated package, integrated marine radars offer good value for hobbyist boaters.

Tracking other vessels with Marine Radar Systems
Whether you are at sea on a relaxing sailing holiday, engaged in a commercial fishing trip hundreds of miles off shore, or carrying freight from one location to another, keeping track of any other objects such as other boats and larger ships in the area is essential if you want to maximize your safety on the water. By using one of the latest generation of marine radar systems, you will be able to take advantage of a number of technologies that make tracking other vessels easier than ever, and even mark their positions and routes on the screen.

The sea can be a cruel mistress, and a change in conditions can come on pretty much instantly. One minute you can be scudding along over practically smooth water, the next, a fog can come down obscuring the world around you, and you can be battling against thirty foot waves and high winds.

This ever changing nature of the ocean means that as conditions change you can face different challenges that can impinge upon your safety. The key to ensuring that you remain as safe as possible is to remove as many of the factors that can change from the overall picture.

Other vessels are often the biggest threat any seaman can face. Smaller boats in particular are often not picked up by the radar systems of large container ships and cruise liners, and this can make things quite dangerous. It is incumbent upon all sailors to keep a check on the sea conditions around them in order to stay safe from other vessels.

Thankfully, even the fastest ships do not usually move at more than about 25 knots, which means that if you have a radar that covers 50 nautical miles, you will have roughly 30 minutes from the moment when you first make contact with another vessel until the time when you would meet, which should give you plenty of time to react and plan your navigation accordingly.

Electronics and Tips on Building a Basic Electronic Circuit

Electronic components are physical entities within the system. Their sole purpose is to affect the associated fields or the electronic via a desired reliable method with the intended purpose of the electronic system. Some of the usual components are transistors, diodes, resistors, and capacitors.

Digital devices are types of electronic systems that use digital signals. Its representation of Boolean algebra is commonly used in mobile phones, computers and other costumer products. Digital devices and other digital circuits are usually made from big assemblies of logic gates.

Analog devices are electronic systems with a constant variable signal. The earliest device invented was the analog. The major difference between digital and analog electronics is its noise, precision and design difficulties.

The process information is programmable in analog electronics. They are more vulnerable to noise as compared to digital electronics. In digital, as the information is programmed and as the signals stay long inside the range value, digital devices represent identical information similar to analog devices.

Digital electronics are much smaller and easier to design as compared to similar analog electronic processes. This is one of the major reasons why the latter is more common and preferred. An analog device should be designed by hand. The procedure is less automatic as compared to digital.

Tools You Need For Electronics Projects

Assembling electronic circuits is a great way of learning electronics, and depending upon the project undertaken, a number of tools and components may be needed accordingly. However there are some basic tools and electronic components which are needed in almost all electronic projects and are a 'must have.'

The first thing to consider is the type of circuit board being used. The circuit board is what the circuit is assembled upon and connected. There are three main types of circuit boards - the breadboard, the strip board, and the printed circuit board.

The breadboard is used for making temporary circuits and does not require soldering whereas the other two types are both permanent and require the parts to be soldered on to them.

When working on printed circuit boards or stripboards, the first tool that is required is a soldering iron. Along with the soldering iron, a solder stand, reel of solder, and solder removal wick would also be required.

In addition to the above, side cutters are required for trimming the component leads, and wire strippers for trimming the wires. A small pair of snipe nose pliers is needed for bending leads or holding small parts in place while soldering.

A flat blade screwdriver, heat sink, and electrical drill will also be very useful when working on electronic projects.

In addition to the tools, a number of electronic components are also required depending upon the project. A good collection to start with will contain capacitors, resistors, variable resistors, diodes, transistors, wires, switches, and a power source.

The Use of UPS Power Supplies in Business

Uninterruptable power supplies have become a major requirement in today's economy with everything being electronic. The importance of UPS power supplies for business has become even more apparent in view of the power shortages many locations have experienced as well as the unexpected blackouts due to accident or malfunction. Any business that incorporates electronic storage or transfer of data would do well to observe the functionality and safety a UPS allows during these moments that had previously caused crisis. From simple small businesses to large corporations and secure facilities that use electronic locks to maintain their security, UPS power supplies have proven their worth in times of need.

While many business locations utilize a backup power source, such as a petroleum-fueled generator, the problem of lost data is still a reality. These power sources sense the loss of electricity and turn on, taking anywhere from ten seconds to two minutes to provide viable energy. This delay can cause whatever projects were being worked on or transfers that were occurring to stop and possibly be lost altogether. The use of a UPS takes the worry out of this occurrence by providing a short supply of power to take up the gap in alternate power sources.

An uninterruptable power supply is typically a battery, or grouping of batteries, that maintains a charge throughout the normal use of electrical current from wall outlets. When the power shuts off, the UPS provides a short-term power supply to continue with work or save data prior to complete power failure. The duration of these power supplies is generally within a five to fifteen minute span, but certainly long enough for auxiliary power sources to become operational. They are also extremely functional when there is a short power outage that is not even long enough for backup power sources to initiate, but would cause the electronics to require rebooting.

Another use of the typical UPS supply is the ability to maintain a steady stream of reliable current to electronics that are sensitive to fluctuations. They can act as a surge/'brown out' protector by preventing the surge or shortage of power from affecting the devices attached to it. They easily take the place of older power strips that only incorporated surge protection as today's energy issues seem more inclined towards loss than momentary excess. UPS supplies are simply a more cost effective way to keep businesses running when everything else is shutting down.

Helping Save the Earth By Recycling Electronics

Look around you and you might realize that electronics are in every appliance, entertainment, or work device that you are using. The invention of electronics and its development has enable daily living to be more compact, fast, and convenient. This might sound comfortable for the end-user, but the apparent global adverse effects of too much pollution contributed by electronics production has been slowly demonstrated by some of the catastrophic disasters of recent years.

Looking at the end result of these adverse effects can be hard to relate the electronics production as a contributor. But think of the parts of your electronic device, say the most common, mobile phone. If your look at this harmless piece of communication gadget, you have the mobile phone body itself, the battery, and all the other mobile phone accessories you can ever think of - from headphones, chargers, speakers and others.First look at the label on your mobile phone battery. If you can read it, some of the most harmful chemicals are inside the battery. If your battery runs out of its useful life, you usually throw it away. Now think of all those harmful chemicals that made up your battery that can be possibly seep through the dump site earth. You can guess that all those toxic wastes can be absorbed by the soil or if thrown in a body of water, it can contaminate 158 gallons of water. The materials of your printer, say the printer cartridge can also be a disposal problem as of this year, you can connect all the printer cartridge and form a circle around the world. Many electronic disposed items are contributing heavy metal scraps as well in the land fill. This makes the trash harder to process for segregation and other recycling processes.

But there is an emerging solution called electronics recycling that can lessen the impact of electronic junk in destroying earth. It can involve a standard process in collecting, recycling, and then reusing of some of the electronic junk that are present in land fills today. This can require new technology in the equipment or machines to be used in handling electronic recycling procedures to reuse the recoverable electronic parts for reuse in the electronics industry.

Some government laws have been slowly promulgated to ratify recycling policies about recycling in most territories. Some cities have started their electronic junk recycling campaigns by starting with awareness campaigns in schools and the general public. Some prize competitions are even geared into action by looking for innovative inventions in creating the ultimate electronic recycling machine. These are some of the community efforts in finding out better methods of promoting recycling all over the globe.

The most evident effort is being required to big electronic corporations for their green campaigns as part of their social and civic responsibility. Most of these are mobile giant companies that collect their brand obsolete or unusable items in branches and they take charge in their proper and approved disposal. Truly, when working together, electronics recycling around the globe can be a very distinct possibility in a few years.

Power Supplies Over Data Cables

Although wireless networks and connections are possibly the best invention ever, there are always two sides to the coin. Having to avoid additional wires running along the floor and tripping someone up as well as additional and unsightly hacking to walls are some positive points. Some of its disadvantages however feature themselves in inaccessibility due to natural and artificial obstructions as well as invaders and hackers tapping into the air space.

To address the aforementioned, it seemed a logical move to consider running an Ethernet connection through existing electrical wiring. As power supplies one's residence or office with electrical energy, it can also function as a channel for data to be transported within the vicinity of the premise. This certainly reinforces the factor on security as well as increases the geography for network access. There is also practically no degradation in network strength as power is constantly switched on unless there is an interruption from the main supply.

Attach a special adapter to the modem or router to connect to the internet. This adapter is then plugged into the wall's power socket to set up the network via the location's power cables. Depending on where the computers or peripheral devices are located, adapters of similar kind are then plugged into the closest power sockets on the walls and connected to these devices. Once everything is connected, a local area network is formed without the need for messy cable configurations, hubs and switches. In the event there is still need for a wireless network, one can be easily set up.

Alternatively, there is also the capability to utilize existing cables for Ethernet connection as conduits to power supplies. Similar benefits as above mentioned include no additional wiring as data and power run over the same physical infrastructure. It is recommended to check regional standards on power and data cabling to avoid untoward incidents such as burning out devices connected to the network, overheating cables, short circuits and fires.

How to Improve Your Automobile With Automotive Electrical Supplies

For many people buying a car is one of the biggest purchases they will ever make, second only to the family home. If you have parted with some well earned cash to invest in a motor vehicle then you will want to make sure that it is well maintained to ensure your safety, the safety of others and the longevity of your automobile. While many people are conscious of the importance of regular servicing in order to keep the engine running smoothly they may not be aware of the significance of a cars electrical system. There are many automotive electrical supplies required to run a vehicle efficiently and gaining an insight into these components will place you in a better position to maintain and improve your motor vehicle.

Sometimes when people buy a car, their budget may not be able to accommodate the many extra features available at the time of the initial purchase and while it is often recommended that extras are fitted to a vehicle at the time of manufacture, for many these may not be an option. Others may enjoy the challenge of buying an older car and restoring it to better than its original state. Looking into the range of automotive electrical supplies available for your vehicle may allow you to make ongoing improvements to your car as your budget allows.

One of the best places to begin looking into the range of products available for your cars electrical system is the internet. Here you will have access to manufacturers and suppliers of these parts and will gain a good insight into what is available, their function and how they can improve your vehicle. From here you can start planning how you can enhance your vehicle in order to maximise its safety and performance.

When dealing with a car's electronics it is of great importance that such work carried out is done by a mechanic who is qualified in this field. Just as you would not entrust your home's electrics to anyone but a fully licensed electrician you should never carry out automotive electrical work yourself or contract anyone other than a certified auto electrician to do the work for you. Auto electricians are specialised in the area of vehicle electronics and have a thorough knowledge of the automotive electrical supplies required for a particular job and have access to suppliers of these parts. In addition to this, if you get work done on your cars electrical system by a specialist in this area and something goes wrong you will be able to take advantage of any warranties that may apply to these parts which would otherwise be void if they are not fitted by an approved mechanic.

There are many ways you can improve your cars performance and if you are passionate about your vehicle then you may wish to look into the range of automotive electrical products available. You may well be surprised by how much you can actually enhance your automobile.

How to Protect Your Electronics From Heat

1.0 INTRODUCTION
In our modern society, we have become very dependent upon our electronic gadgets and appliances. Most households (in the U.S) have Personal Computers with an Internet Connection. If we solely looked at the Personal Computer, we do a lot of thing with this product.

• We communicate with our friends, family members and business associates.
• We conduct financial transactions (e.g., buy or sell products on line)
• We create all kinds of documents (which are very important to our personal and business finances/operations)
• We store and play music (in the form of *.mp3 files)
• We (increasingly) store pictures that have sentimental value (and could be tough to replace if lost).

For many people, anytime their "computer dies", it becomes a major inconvenience in their lives. If you were to look at some other electronic systems that we typically have in our homes, such as

• DVD Players
• Gaming Systems (e.g., Playstation, X-Box, Nintendo, Wii, etc.)
• Audio Entertainment Equipment
• Video Recording Equipment (for you people that like to post videos on YouTube.
• Appliances (such as Central Air Conditioning Systems, Heat Pumps, Microwave Ovens, etc.)
• HDTVs (e.g., LCD or Plasma)

All of these items entertain us, enlighten us and provide us with comfort. These products each require a considerable amount of money to purchase. Further, repairing and/or replacing these products is also quite expensive. Hence, I am quite amazed that people do not do more to protect their investment (in these electronic systems) and do whatever they can to extend the operating life time of these products.

In general, there are three (3) different destructive mechanisms that will either destroy or greatly reduce the operational life-time of your electronics. These three destructive mechanisms are

• Heat
• Electrical Surge/Spike Events, and
• Electrical Noise

In this article, we are going to talk about HEAT. As we discuss Heat, we will cover the following topics.

• How is Heat destructive to your electronics?
• What can we do about heat - How to Protect Your Electronics from Heat and Extend the Operating Life of our Electronics?

2.0 HOW IS HEAT DESTRUCTIVE TO YOUR ELECTRONICS
Heat is an artifact of electronics. All electronic systems generate heat. Electronic systems accept electrical power (current and voltage) from the power line (via the electrical outlet). The electronic system uses a portion of this electrical power to perform work (e.g., the function that you want it to perform, e.g., play a DVD, cook a bag of popcorn, etc). The remaining portion of this electrical power is converted into heat.

However, heat is also an enemy of electronic systems. Few things are more effective in reducing the operating life-time of an electronic system, than raising the operating temperature of the electronic circuitry within your electronic system. If you were to speak with an Electronics Device Reliability expert, he/she would tell you that for every 10 degrees (Celsius) that you raise the operating temperature of an electrical device; you reduce the operating lifetime of that device by 50%. The impact of heat (in shortening the operating life) of your electronics is "huge".

3.0 WHAT CAN WE DO ABOUT HEAT?
As I mentioned earlier, all electronics generates heat. There is no way to prevent electronics from generating the very thing that can destroy it. However, there are a couple of things that you can do to prevent this heat from doing so much damage.

1. You can work to remove this heat from the electronics (as quickly as it generates it), or
2. You can do things to try to help the electronics to not generate so much heat in the first place.

I will address each of these approaches below.

3.1. REMOVING HEAT FROM THE ELECTRONICS
Many consumer electronic systems were designed with "Heat Removal" in mind. Some of these electronic systems (like desktop computers) contain "internal fans". These fans were designed into these systems so that they could blow air through the area in which the system electronics resides. The intent behind having these fans to is blow the heat away from these electronics and to help keep them cool.

Other electronic systems contain "vents" (in their outer case) to provide an "escape path" for heat. Many of these vents are located at the top or in the "back-end" of the electrical system. On this basis, I have the following recommendations to permit the removal of heat from your electronics.

Make sure and keep papers, books, dust and other items from "blocking" the vents of these systems.
Leaving these items on top of your (DVD Player for example) will block the vents, and will not allow for heat to escape from your DVD Player. This will cause the temperature (surrounding the electronics) within your DVD player to rise; which will (in-turn) reduce the operating lifetime of your DVD player.

Make sure that the "back-end" of the electronic system is not "butt-up" against the wall or an entertainment cabinet.
It is important to make sure that there is sufficient air/ventilation space between the vents (in the back end) and the wall/cabinet to allow for Heat Removal.

Make sure and have your appliances (like your Central Air Conditioning system or Heat Pump) serviced.
Whenever these appliances are serviced, the service professional will do various things (like clean out dust and debris from ventilation path), therefore maintaining an unobstructed path for heat to escape from these systems.

Make sure that the fan (inside some of your systems) is working.
If this fan stops working, then you need to get it repaired quickly. Failure to do this will result in your electronic system having an early meeting with the "grim reaper" or an electronic waste disposal site.

3.2 REDUCE THE AMOUNT OF HEAT THAT THE ELECTRONICS GENERATE IN THE FIRST PLACE
Another approach to protecting your electronics from heat is to take steps to try to prevent your electronics from generating excessive heat in the first place. The amount of heat that is generated within an electronic system is often referred to as being related to the following expression for resistive loss: I^2XR, where:

• I represents the amount of current flowing through an electronic system and


• R represents the load impedance (or resistance) within this electronic system; and


• I^2 denotes " I being raised to the 2nd Power, or "I-squared"

From this mathematical expression, you can see that if we were able to reduce the amount of current flowing through an electrical system, this would certainly help to reduce the amount of heat generated within this electrical system.

Tips On Purchasing Electronics for The Home

Finding the right electronics and accessories for your home can often be a little challenging. There are an abundance of different home electronics to choose from, and picking the right ones can be a little overwhelming. With all the latest gadgets to choose from, brand names, and range of styles, it can stagger the mind. Here are a few tips and suggestions to help you not just narrow down your choices to a manageable level, but to also help you make smarter decisions.

The real first tip when it comes to buying electronics and accessories is not to just walk into the home electronics section aimlessly. That lost look on your face is going to attract sales sharks right away, who are going to bombard you with lots of toys and gadgets, You may walk out of the store spending much more than you bargained for. Have a game plan and stick to it.

Your game plan starts by knowing what electronics and accessories you are looking for. For an example, if you are interested in getting a new DVD player or Blue Ray, think about what kinds of features you want, how much you are willing to spend, and what your video library consists of already. While Blue Ray may be the latest movie watching technology available, there are some things to consider. One, these home electronics cost much more than a standard DVD player. Even a player with all the high end features is much cheaper than the basic Blue Ray player. Then you have to consider your video library. Some people may have just spent a lot of time and money switching all their movies from VHS over to DVD, and if you are one of them, do you want to have to do it again for the new format? In addition, while these new movies may have a lot of exciting extras, they are more expensive that buying regular DVD's. Sometimes what you are paying for is all the movies extras, behind the scenes features, etc. While it may be interesting to watch these once, you are probably more interested in just watching the movie rather than knowing how it's made.

One of the most important aspects of buying electronics and accessories is your budget. Know your price range, how much you may be willing to go over, and stick to it. The internet is a wonderful tool to help you in deciding exactly what you are looking for when it comes to home electronics. There are literally thousands of different products at your fingertips. There are also an abundance of review websites available, so you can compare features, prices, and brands of the same product. You can also use the internet to find the lowest costs. This way you know exactly what an item costs, and how to find it.

A smart way to shop for is to know what you have already. Sometimes you may think that a no name brand is cheaper, but this isn't always the case. Let's say that you have a JVC DVD player and you are looking to add a surround sound system to it. While another brand may be a little less expensive, the problem is that your DVD player is keyed to be connected with the same brand of home theater system.

How to Protect Your Electronics From Electrical Surge Events

1.0 INTRODUCTION

In this modern world, we have become very dependent upon our electronic gadgets. We use personal computers to work, communicate with friends, family members or business associates.

We often times store valuable files (such as financial documents, memos, reports, *.mp3 files, and now we also store important personal pictures) onto the Hard Drives of our Computers.

We use the following electronic systems to entertain, educate, enlighten and comfort us.

• DVD Players
• HDTVs (e.g., LCD and Plasma)
• Video Recording Equipment (for those of you upload your videos on to YouTube)
• Gaming Systems (e.g., Nintendo, Wii, X-Box, etc.)
• Central Air Conditioning System, Heat Pumps
• Microwave Ovens

These and other electronics gadgets require a significant investment to obtain in the first place; and are very expensive to repair and/or replace.

And yet, amazingly, we do very little to protect our electronics from damage or attempt to make them last (and serve us) longer.

This article is one of a series of three (3) articles that discusses how to protect your electronics against the following destructive mechanisms that shorten its operating life.

Heat
Electrical Surge/Spike Events, and
Electrical Noise

In this particular article, we are going to talk about "Electrical Surge/Spike Events".

In particular, we are going to discuss the following topics associated with "Electrical Surge/Spike Events".

What are Electrical Surge/Spike Events and How are they generated?

How do you protect your electronics from Electrical Surge/Spike Events?

What are some guidelines that you should use when selecting a Surge Protector?

2.0 WHAT ARE ELECTRICAL SURGE/SPIKE EVENTS?

Electrical Surge/Spike events are typically defined as a "large current/voltage transients that occurs in an electrical signal or the power-line".

Surge events typically last for a few microseconds and are then gone. Similarly, spike events will typically last for a few nanoseconds and are then gone.

NOTES:

a. 1 microsecond = 1 millionth of a second, and
b. 1 nanosecond = 1 billionth of a second.

Both electrical surge and spike events can cause considerable damage to any electronic systems that are electrically connected to these power-line or signal-lines that are carrying this transient current and voltage.

For a typical person that lives in a home and own some consumer electronics, electrical surge/spike events can fall into one of two categories.

External Surge/Spike Events, and
Internal Surge/Spike Events

I will briefly define each of these types of Surge/Spike events below.

2.1 EXTERNAL ELECTRICAL SURGE/SPIKE EVENTS

External Surge/Spike events are called "External" because they occur "External" to (or outside of) your home.

External Surge/Spike events typically originate from one of two sources.

Lightning Strikes (during an Electrical/Thunderstorm), and
Switching events within the Electrical Grid

External Surge/Spike events tend to be very large and damaging (especially if they originate from lightning strikes).

If these external surge/spike events were to enter your home (via the main power line and through the circuit breaker panel), they will destroy pretty much any piece of electronics that is connected to an electrical outlet in your home.

NOTE: These pieces of electronics do not need to be powered on to be destroyed.

They only need to be plugged into an outlet in your home at the time when this catastrophic electrical surge/spike event occurs.

Fortunately, the External Electrical Surge/Spike events do not occur very often (e.g., a few times a year depending upon what part of the world you live in).

2.2 INTERNAL ELECTRICAL SURGE/SPIKE EVENTS

Internal Surge/Spike Events (as the name implies) are generated "internal" (or within your home).

Internal Surges/Spike events typically occur whenever the motor or an appliance (such as an Air Conditioner or the Refrigerator turns ON or OFF).

Internal Surge/Spike events tend to be much smaller than External Surge/Spike events.

However, Internal Surge/Spike events occur much more often than do External Surge/Spike events (several times a day).

Over time, these smaller (though more frequent) internal surge/spike events will do damage to your electronics as well.

Each time a motor of an appliance (such as an Air Conditioner or a Refrigerator) requires surge current (for it to turn on), or anytime the magnetic field (within the motor of an appliance collapses) whenever it is turned OFF, a damaging surge or spike is generated and can propagate throughout some of the power supply lines in your home.

Internal surge events will shorten the operating life of any electronic gadget that is plugged into an electrical outlet in your home.

NOTE: The electronics gadget does not need to be powered ON for it to sustain some damage from these internal surge/spike events.

3.0 HOW TO PROTECT YOUR ELECTRONICS FROM ELECTRICAL SURGE/SPIKE EVENTS

One of the most common ways of protecting many of your electronics from damage (due to electrical surge/spike events) is through the use of "power strips" that contain "surge protection" circuitry within them.

Many power strips have surge protection built in, and in most cases, these types of power strips are clearly marked to reflect this.

CAUTION:

There are some power strips that do not provide surge protection for your electronics.

Often times, people will still (incorrectly) refer to these products as "surge protectors".

If you are looking to purchase a Power strip that contains "Surge Protection" circuitry, make sure that the labeling (on the box that you have in your hands) clearly indicates "Surge protection" or something like that.

If you cannot quickly find those words on the box, then I recommend that you put that Power-Strip box back on the shelf and go find a Power-Strip that has "Surge Protection" clearly marked on it.

3.1 HOW DO SURGE PROTECTORS WORK?

Surge Protector circuitry typically works by having devices (like an MOV - Metal Oxide Varistor) that "sits" between the "power-line" path and electrical ground within the power strip.

Many Surge Protectors will have several of these MOV devices in order to make them more robust.

Under normal operation, these MOV devices will do nothing at all and do not affect the operation of your appliances or electronic systems.

For you electrical engineers out there, I will tell you that these MOV devices presents a very high impedance between the "power-line" and "electrical ground".

If a surge event occurs such that the "power-line voltage" exceeds a certain "threshold" voltage level, then the MOV devices will start to conduct current (and will then present a very low impedance path) between the "power-line" and "electrical ground".

At this point, all of this excessive energy (from the electrical surge event) will be "routed" through the MOV devices (to electrical ground) and will be diverted away from your valuable electronics.

Once the "power-line voltage" returns to a normal level, the MOV devices will then return to their "high-impedance" state and will cease to conduct current between the power-line and electrical ground.

3.2 SHOULD YOU USE SURGE PROTECTORS FOR EVERY ELECTRONIC SYSTEM/ELECTRICAL APPLIANCE IN THE HOME?

In general, you should use surge protectors on all sensitive electronics that you would like to keep and use for some period of time.

If you have Surge Protectors for each of your sensitive electronics, then they will do a very good job protecting your electronics, for the duration that they (the Surge Protectors) function.

3.3 WHAT ARE SOME THINGS THAT I SHOULD LOOK FOR WHEN SHOPPING AROUND FOR SURGE PROTECTORS IN MY HOME?

In general, you should look for the following parameters/metrics whenever you are shopping around for Surge Protectors.

Clamping/Let-Through Voltage
Joules Rating
Response Time (if available)

I will explain each of these items below.

3.3.1 Clamping Voltage:

The "Clamping Voltage" level is also (often times) referred to as the "Let-Through Voltage" level.

Basically, this is the voltage level that will cause the MOVs (inside the Surge Protect system/Power-Strip) to conduct electrical current between the "power-line" and Electrical Ground.

At this voltage level, the Surge Protector will start to shunt the destructive electrical energy (from an incoming surge event) to Electrical Ground and will divert it away from your valuable electronics.

As I mentioned before, the MOVs will continue to shunt electrical current (from the power line) to Ground for the duration that the "Power-Line Voltage exceeds this "Clamping" or "Let-Through" Voltage level.

In general, the lower the "Clamping" or "Let Through" Voltage level the better the protection for your electronics.

Typical values for "Clamping" or "Let Through" voltage level are 330V, 400V, or 500V.

For 120V AC applications, I recommend that you use a Surge Protector with a Clamping Voltage level of 330V.

3.3.2 The Joules Rating

The "Joules" Rating for a Surge Protector will typically define the cumulative amount of energy that it (the Surge Protector) can absorb (throughout its operating life-time) without failing.

In general, the higher the number, the longer the Surge Protector will last and continue to protect your electronics.

Good Surge Protectors are ones that have a "Joules Rating" of 1000J or better.

NOTE: The "Joule" Rating does not reflect the total amount of electrical energy that the Surge Protector will shunt (to Electrical Ground) before failing.

The "Joule" Rating reflects the amount of energy that the components (mostly the MOVs) within the Surge Protector can absorb without failing.

In most cases, whenever an MOV shunts excessive voltage and current to ground (during a Surge Event), it (the MOV) is only absorbing a fraction of this energy.

Most of this energy is "being dumped" to Electrical Ground.

If your Surge Protector is properly installed, then for every joule absorbed by the components (inside the Surge Protector) another 4 to 30 joules was harmlessly shunted from the Power-line to Electrical Ground.

However, each time your Surge Protector responds to a surge event, the MOV devices do absorb some energy, and the cumulative amount of energy that these devices have absorbed moves closer and closer to the "Joules Rating" number and "failure".

3.3.3 Response Time

Surge Protectors do not respond immediately to Surge Events.

There is a slight delay (or response time) before they respond.

The longer this response time, the longer your electronics sits exposed to the incoming surge event. Fortunately, most surge events do not happen immediately either. Most surge events take several microseconds before they reach their peak voltage.

By that time, most Surge Protection schemes (especially those using MOVs) will "kick in" within nanoseconds after the voltage level has exceeded the "Let Through" Voltage.

3.4 DO SURGE PROTECTORS LAST FOREVER?

Just like the smell of a brand new car, Surge Protectors do not last forever.

As these MOVs respond to Surge Events and "shunt electrical energy to ground" over time, they absorb some of that energy.

This process causes "degradation" and "wear and tear" on the MOV devices (and in-turn) on the Surge Protectors as a whole.

Eventually these MOVs will fail in one of two ways.

a. The MOVs will fail to the point that they will no longer shunt excessive electrical energy to ground. In this case, the MOVs (are said to fail in an "Open" state).

Whenever this occurs, all of your precious electronics that is "downstream" from your Surge Protector are now "officially" un-protected and are now vulnerable to the next surge event that comes around.

b. At least one MOV device will fail into a "Short Circuited" Mode. In this case, the MOVs may (though rarely) fail in the "Short Circuit" state.

Whenever this happens, the "failed" MOV device would continue to conduct high currents (from the Power-line to Electrical Ground) even when the power-line voltage is less than the "Let Through" voltage.

This type of failure mode could be very dangerous.

Fortunately, most Surge Protectors will typically have a fuse that will "blow" and will turn OFF the Surge Protector entirely, rather than risk catching on fire.

The main message here is this. Internal Surge Events occur many times throughout the day.

As these events occur, and as your Surge Protectors continue to function and shunt the excessive electrical energy to ground, these Surge Protectors eventually wear out and will need to be replaced.

SOME GUIDELINES ON WHEN TO REPLACE SURGE PROTECTORS:

You should replace your Surge Protectors under the following conditions.

1. Whenever the Green "Protected" Light (on the Surge Protector itself) goes OUT.

2. If you've owned your Surge Protector for more than 3 years.
