| Abstract: | The principles of ultrasonic-based PD monitoring system are introduced. At the same time, it is elaborated that the PD impulse can be imitated by SEAOW and DEAOW in the theoretical analysis. And then, it is described how to apply the ultrasonic-based PD monitoring system in locating the discharge position in the withstanding voltage and PD test of 500 kV GIS, which proves that the ultrasonic-based PD monitoring system is effective in detecting PD points in the withstanding voltage test. Therefore, it is an effective method and basis for timely finding defects in GIS. |
