scope:

This guide covers specific methods of failure mode classifications and analysis for shielded power cables rated 5 kV through 46 kV.

Purpose

The purpose of this guide is to provide an introduction to the concepts of failure analysis, ways in which it can be used, and the value that can be obtained. The guide covers some of the commonly used methods employed in failure analysis and how these methods can be applied in determining the cause of failure for the components used in the construction of an underground power cable system. Ultimately, the guide will serve as a source for documenting known failure mechanisms and will provide a format for the documentation of new failure mechanisms once they have been identified.
