Lightning impulse (LI) voltage testing is an indispensable method for quality assurance of high voltage (HV) and ultra high voltage (UHV) insulation. Not avoidable parasite inductances of the testing circuit provide an oscillation, known as overshoot, at the peak of the lightning impulse (LI). The p...
