Metal Oxide Varistors Used in Power & Energy Industry

TGE can provide various specifications of D30-D115 high-performance AC&DC MOV for AC and DC surge arresters for UHV 1000kV and below AC and ±1100kV and below DC systems.

It has the characteristics of strong resistance to repeated transfer of charges, resistance to multiple harmonics of the DC system, high stability in long-term operation, and excellent protection performance.

Metal-oxide varistors (MOVs) provided by metal oxide varistor manufacturer are a type of voltage-dependent resistor used in power and energy industry applications to limit overvoltages and protect circuits from high-voltage transients and surges. The zinc oxide varistor use zinc oxide grains in a ceramic material to provide a non-linear resistance that increases with voltage. They are designed to have a breakdown voltage that is lower than the normal operating voltage of the circuit, so that when the circuit voltage exceeds this threshold, the MOV diverts the excess current away from the circuit and safely dissipates it as heat. MOV blocks are used in a variety of power and energy industry applications, including surge protection in electrical wiring, circuit protection in power supplies, and lightning protection in overhead power lines.
