Detection and Location of Partial Discharge in Transformers
초록
This paper describes an instrument for the detection and geometric location of partial discharge (PD) source in transformers. This instrument measures electric current pulses and ultrasonic pulses simultaneously, counts the number of electrical pulses and determines the geometric location of PD in transformers. It was found that there is a relationship between partial discharge magnitude and pulse repetition rate when the applied test voltage and oil temperature were varied. Through the laboratory test using model transformer, it was clarified that this detector could be used for detecting and locating PD in the transformer.
