Abstract
The dc voltage sparkover characteristics for a pair of sphere gaps, rod-rod gaps, rod-plane gaps, and insulator strings are described. The dc voltage was generated by a rectifier with rated voltage of 1200 kV and rated continuous current of 0.1 amperes (0.2 amperes for five minutes). The dc sparkover voltage of suspension insulator string whose surface was covered with snow was also obtained. Tests were conducted at the Shiobara outdoor laboratory.
