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...

This corrigendum to IEEE Std 802.1AB-2009 corrects technical and editorial errors identified by the IEEE 802.1 Working Groups maintenance activity.

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 paralleling guide describes and compares control methods of paralleling regulating transformers. The control methods include: master/follower, circulating current, power factor, circulating reactive current and negative reactant methods. This guide presents operating philosophy descriptions, sa...

Electrical and mechanical requirements for liquid-immersed distribution and powertransformers, and autotransformers and regulating transformers; single- and polyphase, withvoltages of 601 V or higher in the highest voltage winding, are set forth. This standard is a basisfor the establishment of perf...
