Partial discharge (PD) detection is an important method to detect the defects in high-voltage bushings. Existing PD detection methods for bushings still have some problems related to the sensitivity and the anti-interference capacity. In this paper, an advanced method for the detection of PD in capacitor bushings is proposed to overcome the disadvantages of the conventional PD detection methods. The...
Transient enclosure voltage (TEV) is a special case of very fast transient over-voltages, which generate during switching of disconnector in gas insulated substation (GIS). It would cause insulation problems such as spark discharge between the flanges, and interference to secondary equipment due to high-frequency electromagnetic radiation. Many studies have been done to investigate TEV above 420kV,...
