Recently, research and inverstigation of multi-lightning strokes have been advanced. Making good use of their information, we have studied the interruption performance of SF6 gas circuit breaker (GCB) on multi-lightning strokes.
In the case of GCB interruption on the trouble by multi-lightning strokes, we illustrate the phenomena occurring in GCB against time, and show the countermove, test method, test equipment and test result on model GCB in the case of most severe phenomenon of them, which is that lightning voltage is imposed on GCB just after interruption.
