PD Monitored AC Voltage Acceptance on 220kV Power Cable Line

AC voltage-endurance test with partial discharge detection on 220kV cable which is 18.6km long


Test time: 2010


Test voltage: 220kV


Cable length: 18.6km


Test conclusion: Single test breakdown


        10pC partial discharge defects are detected


Dissection and verification: Traces of discharge are detected


The first voltage-endurance test with distributed partial discharge detection on high voltage cables with great length in the country: Dissecting and Verifying the Partial Discharge Defects Detected.




A paper about the case was published at the Jicable’11 international conference
