An Experimental Investigation on a Breakdown Mechanism in SF_6 Gas

摘要

Experimental investigations of the breakdown mechanism in SF_6 gas by model electrode configurations are performed for DC and lightning impulse voltages. Electrodes are composed of a rod to a disk. The gap distance is adjusted by changing the radius of the rod electrode. The amount of gap distance and rod radius is kept constant (15mm). Some peculiar phenomena of breakdown characteristics on the gas pressure and the gap distance were observed.
