Abstract :
General methods of detecting partial discharge of transformers include the pulse electric current, DGA, the ultrasound, RIV, the light detection, the radio frequency and the chemistry etc.. A new partial discharge of transformers method based on ultraviolet pulse detection proposed in this paper. After analyzing the relation of partial discharge of transformers with ultraviolet ray and the detection principle, the monitor method of ultraviolet pulse convert to light current pulse and carried on the first step experiment have been designed. As a result, when insulate was break in initial stage, the method of ultraviolet pulse can detect weak discharge and be applicable to on line monitoring for partial discharge of transformers.
