WebJun 1, 2015 · A chopped wave is developed during flashover or puncture. The standard lightning impulse voltage waveform can be chopped on the tail, peak or front. The crest value of the standard tail chopped wave is 10% greater than that of full impulse wave and chopped at 2–6 μs [34]. Such impulses have a rapid voltage collapse on the tail with a … WebImpulse voltage generator is a kind of high voltage generator of impulse wave, used to test the insulation performance of electrical equipment when subject to over voltage (lightning strike) in atmosphere.
