Overvoltage protective devices are key to an effective overvoltage protection strategy, but only if correctly selected and installed.

Lightning, inductive load switching, or capacitor bank switching may cause transient overvoltage conditions in AC line voltage applications such as white goods and appliances. Metal Oxide Varistors ...

An undervoltage or voltage sag is a disturbance that commonly occurs during electrical faults or when equipment is turning on. They are produced when large currents are being drawn on the system. On ...

The function of OVP applied to the input side of the converter is to make the converter immune to input over-voltage transients or surges and to make the converter conform to EMC regulations and other ...

Various electric and electromagnetic disturbances generated inside and outside a car can be hazardous to vehicle electronic equipment. They can degrade performance, cause malfunctions, and even ...

The rate of transient occurrences varies with every power system. Recent studies show that surges of 1kV or less are common — whereas 3kV surges are rare. Protecting against more frequent (internally ...
