Abstract

The ratio of optical pulse numbers to corona current (ROPC) is proposed to study the correlation between UV radiation intensity and current strength during AC corona discharge. It’s found that the ROPC curves rose rapidly before a critical voltage and then the curves flatten with the supplied voltage rising, even if the voltage is increased approximately 1 fold higher than the critical voltage. Finally, according to ROPC curves, a new method of determining the voltage for corona inception is introduced, and a novel quantitative analysis method is put forward to judge the level of corona discharge by the means of optical measurement.
