Application Of Graphic Analysis Method In Partial Discharge Measurement

When we measure the amount of partial discharge, the accuracy of measurement is varied constantly by outer interference, it's important to distinguish partial discharge pulse from interference pulse, so how to judge insulation quality according to partial discharge information became the study direction of many scholars and site personnel.A graphic analysis method is introduced in the paper, which can distinguish partial discharge pulse from interference pulse and measure the amount of partial discharge accurately, analyze all kinds of graphic that is recorded during the process of partial discharge. In chapter one. some fundamental knowledge of partial discharge is discussed. In chapter two^ three and four, the new measurement is elaborated in the principle of graphic analysis and site application. In the end ,the author summarized, and out looked the future.Xu Guoquan(protection and automation for power system engineering)Directed by prof. Hao Yushan...
