High Voltage, Vol 8, Iss 6, Pp 1225-1233 (2023)
Abstract An insulator surface charge may be responsible for flashover along the insulator surface. In this study, experimental investigations of post insulator surface charge are performed using a variety of voltage, gas type, and gas pressure condit

Abstract The multiple reignitions of vacuum circuit braker (VCB) while switching off the shunt reactor in an offshore wind farm (OWF) would produce a high overvoltage. The post‐arc process of ion movement in the vacuum interrupter is analysed. Cons

Abstract The extended grading capacitor (EGC) is a cost‐effective technique to suppress secondary arc. However, whether the use of EGC would weaken the interrupting capability of circuit breakers (CB) or not is still undetermined. In this work, an
