This guide contains general and specific recommendations fo 1 r grounding current and voltage transformer secondary circuits and cases of connected equipment. Although most diagrams included in this guide show relaying applications, the recommended practices apply equally to metering and other areas...

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...
