Computerized underground cable fault location expertise

Power Technologies, Inc. (PTI) developed an expert system and on-line advisor for the Electric Power Research Institute (EPRI). The system, FAULT, provides guidance for field crews to diagnose a cable failure, recommend applicable fault location techniques, and trouble-shoot resulting difficulties which occur during the process of locating underground cable faults on transmission and distribution cable systems. The fault location methods which were identified during development of the expert system are presented in this paper, along with utility statistics from a survey on underground cable fault location.<
