Case Study about the Energy Absorption Capacity of Metal Oxide Varistors with Thermal Coupling
Energies, 2019 Metal oxide varistors are applied today inside modern surge arresters for overvoltage protection for all voltage levels. Their main issue is the thermal activation of their crossing current, which could lead to complete destruction by thermal runaway ...
