A new cable diagnosis system development for MV power cables

Abstract

We have developed the global assessment system for medium voltage power cable systems. Our purpose of diagnostic activity is the economic discrimination and maintenance of bad cables, which is likely to cause cable system failure. We have adopted the aging time constant method to construct the power cable assessment system for our diagnostic purpose. From the field application test results, we have concluded that our system is successful and convenient for the discrimination and maintenance of the bad cables economically.
