A procedure to be used to perform a failure analysis is recommended. The procedure is primarily focused on power transformers used on electric utility systems, although it may be used for an investigation into any ac transformer failure. This document provides a methodology by which the most probabl...

This recommended practice describes how to use probability methods for conducting a reliability analysis of industrial and commercial power systems. It is likely to be of greatest value to the power-oriented engineer with limited experience in the area of reliability. It can also be an aid to all en...

This guide documents methods and designs to mitigate interruptions, equipment damage and personnel safety issues resulting from animal intrusions into electric power supply substations, thereby improving reliability and safety, and minimizing the associated revenue loss.

A detailed test procedure is provided for determining the ampacity derating factor in the following cable installation configurations: block-out or sleeve type cable penetration fire stops; conduits covered with a protective material; tray covered with a protective material; cable directly covered o...

This guideline establishes induced voltage working procedures for underground transmission circuits. A transmission circuit when de-energized will have an induced voltage when in a common duct bank with an energized circuit. The induced voltage may be a possible safety hazard. The induced voltage ma...
