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...

Methods for performing tests specified in IEEE Std C57.12.00 and other standards applicable to liquid-immersed distribution, power, and regulating transformers are described. Instrument transformers, step-voltage and induction voltage regulators, arc furnace transformers, rectifier transformers, spe...

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...

This guide covers the application of indoor and outdoor high-voltage circuit breakers rated above 1000 V for use in commercial, industrial, and utility installations. It deals with usage under varied service conditions, temperature conditions affecting continuous current compensation, reduced dielec...
