Abstract
In this paper, a type of typical PD source, micro-void discharge, is designed and fabricated to imitate the defects in GIS online. The void in solid insulation is carved by the laser inside-carving machine and the machining operation, respectively. Comparing these two kinds of void discharge, a single void discharge form can be obtained using the void carved by the laser inside-carving machine. The void discharge characteristics in power frequency and high frequency are also compared and analyzed. The singleness of discharge forms in high frequency is better. The experimental results will be applied in PD monitoring and materials testing.
