C57.15-1986 - IEEE Standard Requirements, Terminology, and Test Code for Step-Voltage and Induction-Voltage Regulators

Standard

Superseded

Standard Details

This IEEE Standards product is part of the C57 family on Power Distribution and Regulating Transformers. Electrical, mechanical, and safety requirements are set forth for step-voltage and induction-voltage regulators, single-phase and three-phase, oil-filled and dry-type, not exceeding 2500 kVA of regulation for three-phase units, or not exceeding 833 kVA of regulation for single-phase units. These provide a basis for the establishment of performance, limited electrical and mechanical interchangeability, and safety requirements of equipment described and for assistance in the proper selection of such equipment.

Existing Standards	Superseded C57.15-1999 - IEEE Standard Requirements, Terminology, and Test Code for Step-Voltage Regulators Electrical, mechanical, and safety requirements of oil-filled, single- and three-phase voltage regulators not exceeding regulation of 2500 kVA (for three-phase units) or 833 kVA (for single-phase units) are covered.
	Superseded C57.15-2009 - IEEE Standard Requirements, Terminology, and Test Code for Step-Voltage Regulators Description of design types, tables of 50 Hz and 60 Hz ratings, supplementary ratings, construction, and available accessories are provided. Methods for performing routine and design tests applicable to liquid-immersed single and three-phase step-voltage regulators are described. Winding resistance measurements, polarity tests, insulation power factor and resistance tests, ratio tests, no load loss and excitation current measurements, impedance and load loss measurements, dielectric tests, temperature tests, routine and design impulse tests, short-circuit tests, control tests, calculated data, and certified test data are covered.
	Active C57.15-2017 - IEEE/IEC International Standard- Power transformers - Part 21: Standard requirements, terminology, and test code for step-voltage regulators This document describes electrical, mechanical and test requirements of liquid-immersed, single- and three-phase, 50 Hz and 60 Hz, self and forced-air cooled, distribution, overhead and substation, step-voltage regulators, 1 000 kVA (single-phase units) or 3 000 kVA (threephase units) and smaller, 34 500 volts and below (2 400 V minimum) and their associated controls. Requirements, references and definitions relevant to either IEC or IEEE contexts are given and their use is described in Clause 4.
