It would be very convenient if the electricity available from household and office outlets was always even and consistent. However, for a variety of reasons, the electrical supply in most locations often varies wildly, from lower than expected, to voltages much higher than you might imagine. These voltage “transients” or “surges” can reduce the life of many electrical products and appliances, and quickly kill others.
Electrical storms are one cause for these surges. Even without a direct strike, lightning can induce strong electrical surges in nearby electrical lines, sending these surges into our homes and businesses, wreaking havoc on valuable electronics and other sensitive electrical systems and devices. Many of our electrical devices and appliances contain built-in surge control systems, but it’s difficult to know which of these are protected and which aren’t. Built-in surge protectors aren’t always robust enough to protect electronics from severe transient events, and many of these surge arrestors have a limited life, breaking down over time after withstanding multiple surges.
Lightning isn’t the only cause for inconsistent voltages. Sometimes, these are caused by the sudden inrush of current required to feed air conditioners and other large appliances as they are switched on at intermittent intervals. Shop tools and nearby construction projects are other common causes for electrical transients.
Most of us are familiar with short extension cords equipped with surge protectors and multiple outlets. An uninterruptible power supply is another common solution, often used to protect computer systems and provide extended working time when power outages occur. While both types of products provide protection from transient voltages, an even better form of protection is a surge protector designed to protect the entire electrical system in a home or office, including higher voltage appliances like stoves and refrigerators. The electricians at Bryant Electric Services are trained and equipped to install “whole house surge protectors.” If you would like more information or a bid, please contact us.
