Abstract This paper presents a partial discharge (PD) pulse extraction and starting point identification method by time of arrival (TOA) method using threshold method, energy method, AIC method, and Gabor method, which aims to achieve the automatic location of PD sources. PDs location based on the above mentioned algorithm firstly carried out in the laboratory. Then, to verify the algorithm, the authors conducted the PDs source location of switchgear which existed some suspected discharges by routine inspection on-site in a substation of Wuzhou Power Bureau. The localization results showed that the upper cabinet of the switchboard existed partial discharge and the disassembling results of the switchboard verified the inspection and location results.

Key words： threshhold method energy method AIC method Gabor method time of arrival partial discharge location
