Abstract :
This study is aimed to sophisticate the simultaneous measurement system of electrical and optical information of PD phenomena, i.e. PD current and PD light emission phenomena. Using this sophisticated system, we can discuss and clarify the breakdown mechanism as well as the discharge condition such as streamer and leader discharge in SF6 gas or new SF6 substitute, based on observation results. In this paper, we described the structure and significance of the time and spatial-resolved spectroscopic measurement system. Then, we showed the measurement concept of PD phenomena and the main results obtained from this system with an electrode system forming non-uniform electric field in SF6 gas under ac high voltage application.
