The increasing use of integrated circuits in modern electronic systems has resulted in a growing awareness about lightning overvoltage hazard. The integrated circuits, especially large-scale ...

A surge suppression device (SPD) tries to divert most of the transient energy away from the load, via a low-impedance ground path. Most SPDs use metal oxide varistors (MOVs) in the suppression circuit ...

Several types of devices are employed in electronic systems to protect against voltage transients, power surges, and excessive voltage or current. Varistors is one of those devices that protect ...

While 80% of surges originate internally from normal operations like motor starts and VFD inverter operation, external causes like lightning and utility switching also demand industrial-grade surge ...
