Comparative Studies on Degradation of Varistors Subjected to Operation in Surge Arresters and Surge Arrester Counters

Archives of Metallurgy and Materials, 2020
The paper presents results of investigation of microstructure and micro-hardness for material of ZnO varistors applied to 110 kV surge arrester and surge arrester counter. The research combined two pairs of varistors, each consisted of one varistor subjected before to operation, while the other one was brand new unit and constituted a reference.
