In rare cases, power surges can lead to electrical fires, which can damage or even destroy the entire home. A power surge is a fast yet short duration of electrical transients in current, voltage or transferred energy that happens in an electrical circuit.Typically a power surge is caused by an oversupply in voltage either from the power company or from various external sources, although an oversupply of current is also possible; either way it affects the overall power moving through the electrical lines, hence the term power surge. Power surges can originate from an electric utility company during power grid switching. In power systems in particular – and this is likely the most common context that we relate surges to – a surge, or transient, is a subcycle overvoltage with a duration of less than a half-cycle of the normal voltage waveform. Power Wall outlets normally supply power called 120 volts AC power. A surge suppressor (sometimes optimistically called a \"surge protector\") is a device inserted in the alternating current ( AC ) utility line and/or telephone line to prevent damage to electronic equipment from voltage \"spikes\" called transients. With alternating current the voltage rises and falls in a Surges can be generated internally and externally of the home. Many power strips are just glorified extension cords without any protection. have to enter through the electrical panel indicates a good In most cases, when a surge arrester intercepts a power surge, it fuses itself to prevent transmission. where you live, your home experiences power surges. A power surge is a transient wave of voltage, current or power in an electrical circuit. A number of different things can cause this to happen. This causes an increase in the electrical potential energy, which can increase the current flowing to your wall outlet. Power surges can vary in duration house and its contents should be assessed individually.
