impulse voltage test pdf

of the test voltage, under specified conditions 3.1.2 steep front impulse fast-front voltage impulse whose time to peak is less than that of a standard lightning impulse but not less than that of a very-fast-front voltage as defined in IEC 60071-1. Severe chop wave. The overshoot compensation (6) improves the impulse voltage wave shape for highly capacitive test objects.
