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 recommended practice provides Instrument Description templates which are compliant with IEEE Std 1671.2-2012, that providers of synthetic instruments should use to describe waveform generators, digitizers, external local oscillators, and up and down converters. These synthetic instruments may b...

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...

Small power transformers have become a significant element in distribution systems supplying large commercial customers like major resort hotels and site-specific industrial customers that desire the local utility to own, operate, and maintain the serving transformer. These transformers can range in...

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...
