It is becoming extremely necessary to install whole house surge protectors, due to the increasing addition of electrical appliances in homes, and the rising cost of replacement and repair. A power surge is a sudden and drastic increase in electrical power that is being supplied. Power surges and stray electronic charges can damage delicate components of an electrical appliance, or the appliance, altogether. If the power surge is too high, it could trigger a spark that could possibly cause a fire.
A common misconception that many people have, is that their appliances are protected from power surges if they are plugged into a surge protection strip, or a power outlet strip. However, stray electric charges can enter a home, through telephone and cable lines, as well. Surge protection strips function mostly as extension cords, than surge protectors, as they only offer power supply but no protection against electrical surges.
Types of Power Surges
Power surges are of two types―lightning generated power surges and those generated by minor fluctuations. The minor power fluctuations are generated due to home appliances being rapidly turned ON/OFF, or due to a tree branch falling over an electric or phone line. Both types of power surges can cause a lot of damage to electrical home appliances.
Things to Consider
The best way to protect electronic home appliances, is to install a whole house surge protector. It is better than using a surge protection strip, as it protects the entire house and not just plugged in appliances.
Whole house surge protectors are devices that absorb voltage spikes that rise above a certain level, causing harm to electronic devices. They are also known as whole house voltage surge suppressors. The energy absorbed from voltage spikes is sent out in different directions, through underground wires.
These are available in various designs. Some of them are remounted as circuit breaker box devices, or are built into a circuit breaker. Some models also provide protection for phones, modems, and television cable lines. The factors to be considered while choosing these for your home are, its performance specifications, maximum surge current, reaction time, clamping voltage, and total energy dissipated.
There are a number of companies that provide surge protection services. These include, checking and testing of the electrical grounding of your home by a qualified electrician, and the installation of a surge protection system. This system usually provides protection for home appliances like air conditioners, refrigerators, dishwashers, etc., and plug-in devices.
Installing a house surge protection system can save you a lot of money, that you would otherwise have to spend on the repair and replacement of your home appliances in case they get damaged.
