The waveform of a standard lightning impulse differs greatly from those of actual lightning surges acting on GIS. This raises the problem of the equivalence of the standard lightning impulse. This report describes the effect of voltage waveforms on insulating performance in an SF 6 gas gap subjected to fast oscillating impulse voltages simulating actual lightning surges, and the evaluation of V‐t characteristics by applying the equal area criterion. © 1997 Scripta Technica, Inc.
