How the Zinc Oxide Varistor Works

The working principle of the Zinc Oxide Varistor is simple yet effective. Under normal operating conditions, the MOV remains inactive, offering high resistance to the circuit. However, when a transient voltage surge occurs, the voltage exceeds the varistor’s threshold, causing its resistance to drop sharply. This allows the MOV to conduct and divert the excess voltage away from sensitive components, preventing potential damage.
