Specifying Cable System Reliability

摘要

Consulting engineers have been specifying DC Hi-Potting to commission newly installed power cable systems for the past century. While this cable test is very popular, the question remains whether it is effective in locating cable system defects that may cause future cable system failures? If not, is there an adequate alternative to ensure that the cable system is free of defects and has been properly installed per the requirements of IEEE cable system standards? Here, I will address this topic based on experience obtained over the past ten years. But first, some history.
