The chopped-impulse test is often specified to represent the severe condition of stress within the apparatus (particularly in winding structures) produced by collapse of the voltage when a line or bus insulator flashes over near the apparatus. This test is a lightning-impulse test with the tail of the impulse chopped after the crest at some […]
