Diagnosing the health of your underground cable

摘要

Partial discharge (PD) testing of in-situ power cable and accessories is an emerging technology. The development of many diagnostic systems-de-energized and energized-provide much data. However, the key for success is in better data interpreting and understanding skills. These skills will volve as the technology progresses, the data analysis tools improve and the test bank data increases. The industry now has access to several commercially available diagnostic tools, yielding much experience for usage on paper-insulated lead cable (PILC) and solid dielectric polymeric insulated cables.
