Paper Abstract

This paper measures and analyzes the waveforms of recovery voltage and shield potential. It discovers that in the shield potential waveform, when the breaking current is close to its limit, an irregular distortion happens to it. It is proved that not only the speed of post-arcing recovery process varies, but also non-stability exists in the process. This non-stability increase as the breaking current reaches its limit. The non-stability may cause post-arcing breakdown and breaking failure.
