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...

Corrections made to Clause 11, Clause 17, Annex C, and Annex H in IEEE Std 80-2013. (Incorporated into IEEE Std 80-2013.)

The neutral grounding of single and three-phase ac electric utility primary distribution systems with nominal voltages in the range of 2.4 kV34.5 kV is addressed. Classes of distribution systems grounding are defined. Basic considerations in distribution system grounding concerning economics, contro...

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...

Drawout-type ground and test devices for use in medium-voltage metal-clad switchgear rated 4.76 kV through 38 kV are covered. The description, design, and testing of these accessory devices that are inserted in place of drawout circuit breakers for the purpose of grounding and testing are also cover...
