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.

PC57.15
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, 1000 kVA (single-phase units) or 3000 kVA (threephase units) and smaller, 34 500 V and below (2400 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.
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.
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.
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
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.
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.
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
No Inactive-Reserved Standards
