All homes and businesses experience electrical disturbances, such as voltage transients or surges, voltage sags and swells, and electrical interference or “noise.”
Modern electronic appliances and equipment, including kitchen appliances, heating and cooling systems, lighting systems, and office and entertainment equipment can be damaged by
these electrical disturbances.
The damage may occur suddenly, during a lightning storm for example, or it can occur gradually due to the smaller voltage transients that regularly occur as other nearby equipment switches on and off. Surge suppressors can reduce the likelihood of damage.
