FAULT LOCATION STRATEGIES ON POWER CABLES USING OFFLINE METHODS INCLUDE TIME DOMAIN REFLECTOMETRY ( TDR)

The purpose of this study is to investigate the feasibility of offline fault location and state of health technologies for airport series circuits used to provide power to light fixtures on the runway. In current series circuits, only some ground faults can be detected and no automated fault location or state of health features are available. Fault location is currently performed with an isolation tester and a”divide and conquer”-methodology which is very time consuming and personnel intensive.
