Abstract
In view of the increasing application of UHF to the detection of partial discharge, and in combination with the case of UHF technique for GIS patial discharge detection in Guangdong Power Grid substations, this paper analyzes the advantage of UHF based online monitoring technique, and carries out test research of the application effect of PDM UHF system for patial discharge detection. The test results and practical application show that the UHF online monitoring technique can improve the efficiency of detecting GIS partial discharge, and thus have very good application prospect. The key of the technique to improve the monitoring sensitivity is to select right installation position for transducers. In addition, UHF technique is better used with ultrasonic positioning technique for a full-closed GIS device.关键词
