Research on transient insulation numerical analysis method of circuit breaker in GIS under lightning impulse voltage

In order to reveal the process of insulation destruction of circuit breaker in GIS under lightning impulse voltage, a new method of transient insulation numerical analysis is described in this paper. A combination of the electromagnetic transient analysis method and optimised charge simulation metho...
