Time Delay Characteristics of Radiated Electromagnetic Wave with Partial Discharge

부분방전시 방사전자파의 시간지연특성

The most of faults in gas insulation of power facilities are caused by partial discharge. Therefore we simulated partial discharge and measured the radiated electromagnetic wave emitted from partial discharge in the $SF_6$ gas by biconical antenna. This paper describes time delay characteristics of radiated electromagnetic waves with distance between antenna and discharge source.
