1. On-line time domain reflectometry diagnostics of medium voltage XLPE power cables
Sammanfattning : Degradation of XLPE insulated power cables by water-trees is a primary cause of failure of these cables. The detection of water-trees and information about the severity of the degradation can be obtained with off-line measurement using dielectric spectroscopy. In many situations only a limited part of the cable may be degraded by the water-trees. LÄS MER
