The Influence of Ni2O3 Doping Concentration on the Alternating Current Aging Characteristics of ZnO Varistor

open access: yesInternational Journal of Ceramic Engineering & Science
When the surge arrester is subjected to the working voltage for an extended period, it undergoes alternating current (AC) aging, which degrades the arrester's parameters and affects the safety of the power grid.
