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.

Investigation of the Effect of Processing and Sintering Parameters on Voltage-Dependent Variable Resistors for Controlling Voltage and Leakage Current in ZnO-Based Compositions

مواد نوین
Introduction: Voltage-dependent resistors, known as varistors, have wide applications in the electrical and electronic industries due to their protective role against the destructive effects of sudden voltage spikes. This research investigates the impact

PROCESSING AND CHARACTERIZATION OF LOW-VOLTAGE VARISTORS

, 2014
ZnO seed particles and Cr2O3 were used in this study to control the microstructure of ZnO varistors. The seed particles were prepared by adding 1.0 mol % BaO to ZnO. The powder was then calcined at 800-degrees-C for 2 h, pressed into pellets and sintered
