Condition Monitoring and Fault Detection in Cables using Line Impedance Resonance Analysis

Abstract

Line Impedance Resonance Analysis is a powerful technique to determine the location of water trees and physical damage in all cables, from LV to EHV. The technique, which uses the concept of frequency-domain reflectometry, was originally developed for nuclear plants and has now been commercialized for practical applications in the field of condition monitoring as well as fault location.
