Abstract :
Flashover tests were conducted by using three kinds of positive polarity switching impulses, exponential, damped oscillatory and linearly rising impulses. The influence of switching impulse wave shape on the flashover characteristics of air gaps was investigated and the basic data were obtained concerning the minimum 50-percent flashover oltage of air gaps and the time to crest of these switching impulses.
