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

International 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.

Advances in the synthesis of ZnO nanomaterials for varistor devices [PDF]

Journal of Materials Chemistry C, 2013
ZnO based varistors are widely used for overvoltage protection in many electrical and electronic circuits, at voltages ranging from a few to over a million volts. By careful control of the microstructure, through nano-structuring by chemical routes, it should be possible to produce varistors with high breakdown voltage (Vc), as this is proportional to ...
