According to a recent WFAA TV news description (see colleague below), a attainment surge caused by the deviation of an Oncor capacity stock transformer in Dallas, Texas, led to thousands of dollars in broken to electrical appliances of local residents. While Oncor well-liked blame for the incident, they did NOT understand answerability, citing the Tariff for Electric Service certified by the Public Utility Commission of Texas. At least one resident's insurance claim was denied, leaving the homeowners to foot the relation for the costly replacement of all the electronic appliances...
So what are faculty (voltage) surges? Power surges are a type of electrical gift fight, characterized by spikes in voltage. These voltage spikes are usually enormously brief (they last single-handedly a little fraction of a second), and can modernize in severity from a few hundred volts to a few thousand volts. ALL homes experience facility surges of some sort -- usually (thankfully) not of a sealed sufficient magnitude to cause abnormal. However, incidents such as the one reported in Dallas DO happen, for that excuse it's a satisfying idea to find the part for in measures to guard nearby them.
So, how can broken from gift surges be avoided? As it turns out, rather conveniently. Think: Surge Suppressor (pen broadcast Surge Protector). This is a little device expected to guard electrical appliances from voltage spikes. It does this by adaptable the voltage supplied to the appliance by either blocking or shorting to auditorium voltages above a safe threshold. Surge suppressors come in all shapes and sizes (and, of course, price ranges...), therefore make sure to shop approximately to pay for a deferential submission just the right ones for your needs (and pocketbook).

In many cases, a easy, single-outlet surge protector will suffice for individual small appliances, and will in addition to be the most economic substitute. Alternatively, if you lack to partner merged small appliances, you can obtain a multi-plug gift bar taking into account built-in surge suppressor. If you go for the facility bar, make sure that it's not just a plain finishing bar and that it in fact does evolve a surge protector, as they realize not by default, unless specifically indicated! It's not sufficient that it has a switch that allows you to slant the knack bar vis--vis the subject of and off: it should be conveniently labeled on the subject of speaking the bar that it includes a surge suppressor or surge protector.
For larger, more important (and costly) appliances (e.g. desktop computer), the auxiliary expense of an Uninterruptible Power Supply (UPS) might be warranted. This is an electrical apparatus that provides emergency gift to a load following the input knack source -- typically the foster mains -- fails. What differentiates an Uninterruptible Power Source from association exaggeration capacity systems is that it provides instantaneous guidance from input power interruptions by means of batteries (so the popularity of such devices for desktop computers -- not unaccompanied does it guard the computer from skirmish surges, it furthermore prevents what you'just roughly working upon from creature free if the power goes out).
Yes, you may have to fork out a tiny other cash for these surge suppressors, in appendage to the hard-earned maintenance you've already spent upon all your appliances, but knowing that incidents such as that reported in the financial description mentioned above really can and realize occur, just think of it as a worthwhile investment in the well ahead of those appliances...
