Mov metal oxide varistor

The structural characteristics of the varistor varistor metal oxide different from ordinary resistor, which is based on nonlinear characteristics of semiconductor material made of
Ohm's law to comply with ordinary resistor, and varistor voltage and current is nonlinear relationship was special. When applied across the varistor voltage is lower than the nominal rated voltage, resistance value varistors approaches infinity, almost no current flows through the interior. When the voltage across the TGE Metal Oxide Varistors(MOV) slightly higher than the nominal rated voltage, the varistor will quickly breakdown conduction by a High Performance Varistor state to a low resistance state, current also increases dramatically.
