Impedance Spectroscopic Study of Zinc Oxide Varistors

, 1991
Polycrystalline zinc oxide containing oxides of bismuth, cobalt, manganese and antimony is found to exhibit highly non-ohmic I–V characteristic arising due to the presence of schottky barriers at the grain boundaries.

An Experimental Study of the Failure Mode of ZnO Varistors Under Multiple Lightning Strokes

, 2019
In this study, in order to explore the failure mode of ZnO varistors under multiple lightning strokes, a five-pulse 8/20 μs nominal lightning current with pulse intervals of 50 ms was applied to ZnO varistors.
