Abstract

In this paper, we analyzed the frequency spectrum of radiated electromagnetic waves which is generated by corona discharges as a basic study to develop a on-line diagnostic technique for power facilities installed in a closed-switchboard. Five types of electrode system were arranged to simulate corona discharge. The experiment was carried out in an electromagnetic shielding room, and the measurement system consists of an Ultra Log Antenna and an EMI Test Receiver. These results showed that the frequency spectrum of corona discharges exists widely in ranges from 30 to 1,000 [MHz].
