Metal Oxide ZnO-Based Varistor Ceramics [PDF]
, 2011 A varistor is a type of resistor with a significantly non-ohmic current-voltage characteristic. The name is a portmanteau of variable resistor, which is misleading since it is not continuously user-variable like a potentiometer or rheostat and is capacitor rather than resistor at low field. The most famous type of varistor is metal oxide varistor (MOV),

Reliability evaluation of metal oxide varistors for maintenance scheduling [PDF]
WIT Transactions on Ecology and the Environment, Vol 91, 2006 Surge overvoltages result in a power system from overcurrents due to atmospheric discharges, induction phenomena, switch operations or faults. In order to reduce the probability of injuries to people and of failure of electrical and electronic systems, power systems within a structure should have adequate equipotential bonding. Surge protective devices

Research on influence of double energy absorptions on dynamic volt‐ampere characteristics of metal oxide varistors [PDF]
High Voltage, Volume 10, Issue 1, Page 78-87, February 2025.Abstract Metal oxide varistors (MOVs) are extensively employed in DC circuit breakers (DCCBs) to suppress overvoltage, dissipate energy and build up voltage after interruption. Despite their widespread use, the performance of MOVs under short‐time, double energy absorption conditions is not well understood, posing a challenge to their application in ...

Tunneling of photoexcited carriers in metal oxide varistors [PDF]
Journal of Applied Physics, 1975 ZnO-based ceramic varistors exhibit photocurrents which vary in a highly nonlinear manner with applied voltage. It follows that varistor behavior is controlled by electrical barriers at the ZnO-grain–intergranular-layer interface.
