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.
