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.)

Information on the concepts of protection of ac transmission 1ines is presented in this guide. Applications of the concepts to accepted transmission line protection schemes are presented as well. Many important issues, such as coordination of settings, operating times, characteristics of relays, mut...

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...

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...
