Considerations on the Propagation of Partial Discharge Pulse in 3-Phase Power Cable Systems including Cross-Bonding Joints

3상 전력케이블 크로스본딩 접속에서 부분방전 펄스 전파 특성 고찰

In this study, the propagation characteristics of partial discharge(PD) pulses in the 3-phase cable systems including crossbonding joints were discussed. For the purpose, experiments for 22.9kV CNCV cables were performed using simulated PD pulses, and on-site partial discharge measurements were carried out for the 345kV XLPE cable system.
