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
