Semiconductors are materials that have a small electronic bandgap. This bandgap prevents current from flowing at absolute zero, but thermally excited charge carriers can begin to flow at higher ...
Abstract: With the development of ZnO arresters towards high voltage gradient and miniaturization, more stringent requirements are put forward for ZnO varistor ceramics, and higher requirements are ...
Abstract: Metal oxide varistors (MOVs) are well established as surge arrestors to protect AC power transmission and distribution apparatus. Unlike the rare lightning-induced surges in AC application, ...
