Metal Oxide Varistor Polarization from an Initial Transient.

Abstract

Metal oxide varistors (MOV's) are polarized by the initial transient shunted. This effect is seen in the early part of the current - voltage (I-V) curve as a decrease in clamping voltage and increase in standby current. The magnitude of degradation is a function of the measured polarity relative to the pulse polarity of the initial transient. This report presents alpha and I-V degradation curves for all sizes of MOVs tested. Keywords: Varistor polarization; Transient protection; Circuit protection.
