Damage from transient overvoltages is one of the leading causes of equipment failure. Although some pieces of equipment may come equipped with transient protection, others will need some form of ...

Transient voltage and transient current events, commonly known as power surges, voltage surges, or current spikes, are a relatively frequent occurrence for many electronics applications. Transient ...

What is a metal oxide varistor? The Metal Oxide Varistor or MOV is a voltage dependent, nonlinear device that provides excellent transient voltage suppression. The Metal Oxide Varistor is designed to ...

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 ...
