| Abstract: | As an effective resort of finding potential insulation defects of power transformer in its early stage, the partial discharge (PD) detection technology has gained great breakthrough on the issue of anti-interference with the introduction of UHF method. This paper summarized the present status and characteristics of several important PD detection and location methods, pointing out some key problems of PD location using the newly developed UHF approaches in its current circumstances of development. |
