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 ...

Electrohydraulic effect of microsecond pulsed discharge in transformer oils
High Voltage, Volume 10, Issue 1, Page 137-145, February 2025.Abstract The physical process of microsecond pulsed discharge in transformer oil is the foundation for studying the initial mechanics of faults in ultra‐high voltage transformers. However, the microsecond‐scale electrohydraulic effect in transformer oil has not been investigated yet.
