Various analytical methods are available for predicting the performance of insulation stressed by lightning voltages of non-standard waveshape. This paper describes experimental and analytical studies for evaluating the effectiveness of the prediction methods. Flashover characteristics of typical line insulation were determined using standard and non-standard impulse waves viz., long front, partially chopped and oscillatory impulses. The standard impulse data were used to calibrate the… Expand
