2. 1. Development of on-line diagnostic methods for medium voltage XLPE power cables

   Author : Valentinas Dubickas; Hans Edin; Roland Eriksson; Matti Lehtonen; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Elektroteknik;

   Abstract : On-line diagnostics of power system components is an important area since it allows the diagnostics to be performed at regular intervals during the normal operation of the components. This combined with reliability centered maintenance could lead to reduced customer outages. READ MORE

4. 2. On-line time domain reflectometry diagnostics of medium voltage XLPE power cables

   Author : Valentinas Dubickas; Roland Eriksson; Tord Bengtsson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Elektroteknik;

   Abstract : 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. READ MORE
