Abstract
Published data on sparkover characteristics of high-voltage protective gaps with 50-200 cm spacings have been reviewed and statistically analyzed. The results are presented, including: volt-time curves for times to sparkover up to 8 Ms, average critical sparkover gradient for various types of gaps for lightning impulse and for switching impulse, and average sparkover gradient for power-frequency voltage. Wherever justifiable, 95 percent confidence intervals are also given.
