This study analyses a gas insulated switchgear explosion accident caused by a failure of the
circuit breaker (CB) in a thermal power plant, which resulted in the explosion of the CB and …

This paper presents an analysis of a very fast transient overvoltage (VFTO) experienced by a
550-kV gas-insulated substation (GIS) that caused the failure of a disconnector switch (DS) …

This paper discusses the analysis of arc conductance in a gas circuit breaker (GCB) during
current interruption process and the investigation method of the interruption capability. There …

Although it has been observed that gas insulated substations (GIS) are more reliable than
open air substations, there is concern that switching operations performed within GIS at …

A study was conducted to estimate transient breakdown voltages (V/sub BD/s) between
contacts of a puffer-type SF/sub 6/gas circuit breaker. When contacts are opening …

This paper aims to investigate the fault arc's arcing process and the arcing electrode's
temperature distribution characteristics. A series of 220VAC fault arc experiments were …

[en] Successive fire due to a HEAF (High Energy Arc Fault) event in a high voltage metal-
clad switchgear was identified at the Onagawa nuclear power plant after the Great East …

Simulations of three-phase faults at the generator terminals have shown the existence of
non-zero currents in all three phases for several cycles. Particularly in the application of …

Internal fault arcs in power step‐up transformers occasionally occur at different locations
inside the tank. In this study it has been investigated to what extent generator circuit …

Arcs in gas circuit breakers have been regarded as resistances when a zero-miss current
interruption phenomenon has been simulated by a computer. However, the model involved …
