Abstract

A typical defect of partial discharge in GIS was analyzed.Ultra high frequency detection

ultrasonic detection and time-of-arrival method were adopted to precisely localize the discharge position with consideration of the equipment structure

and X-ray detection technology was used for nondestructive inspection.The X-ray detection result was consistent with the localized positions obtained by the detection methods mentioned above.In addition

the advantages and disadvantages of the detection methods were summarized

and different combinations of the detection methods were suggested for different detection purposes.
