Abstract :
In this paper data are presented on spark-over values of rod gaps, insulators, bushings, sphere gaps, and solid insulation for a range of spark-over times of approximately from 0.2 to 4 microseconds. The problems of accurate measurement that are involved are also discussed, and a shielded resistance voltage divider is described.
