Varistors, also known as voltage-dependent resistors, are used as part of surge protective devices (SPDs). Varistors are designed to provide protection against transient overvoltages by limiting the voltage across the device to a safe level. Varistors are usually composed of sintered material consisting of zinc oxide grains embedded in a ceramic matrix. When an overvoltage occurs, the varistor exhibits a low resistance, allowing a large current to flow, thereby reducing the voltage across the device. Varistors are available in both AC and DC versions, with a variety of ratings to suit different applications.

High Gradient MOV (Metal Oxide Varistor) GIS Arresters are surge arresters designed specifically to protect sensitive GIS (Gas Insulated Switchgear) equipment from power surges. The arresters contain a unique combination of metal oxide varistors (MOVs) that are specifically tailored to the application. The MOVs are configured in a large variety of series and parallel arrangements to provide the optimal clamping voltage to protect against a wide range of surge voltages. High Gradient MOV GIS Arresters are typically used in industrial and commercial applications where the power system is sensitive to damage from lightning strikes, power outages, and other power system disturbances.

It is a type of overvoltage protection device that is commonly used in DC arresters. It works by diverting excess current away from the protected circuit and dissipating it as heat. This prevents the circuit from being damaged by excessive voltage. MOVs are typically made from a combination of zinc oxide and other metal oxides and offer excellent protection against surges and spikes in voltage.
