Phase IEEE Transformer Standards

This guide provides background information and general recommendations of instrumentation, circuitry, calibration, and measurement techniques of no-load losses (excluding auxiliary losses), excitation current, load losses of power, and distribution transformers. The test codes, namely,...

This part of IEC 60076 covers the requirements for phase-shifting transformers of all types. The scope excludes transformers with an unregulated phase shift. This document is limited to matters particular to phase-shifting transformers and does not include...

This recommended practice covers routine impulse tests performed on distribution transformers, as required in IEEE Std C57.12.00™, and described in 10.4 of IEEE Std C57.12.90™-20151. Distribution transformers covered by this recommended practice are liquid-immersed,...

To aid in the interpretation and application of the impulse testing requirements of the IEEE Standard Test Codes for Transformers. Purpose This guide is written primarily for power transformers, but it is also generally applicable to distribution and instrument...

This standard defines the terminal markings and connections for distribution, power, and regulating transformers covered in the IEEE C57™ series of standards, guides, and recommended practices. Purpose The standard provides a consistent method for terminal markings and connections for...

This part of 60076 International Standard specifies requirements of liquid-immersed three-phase and single-phase converter transformers for use in high voltage direct current (HVDC) power transmission systems including back-to-back applications. It applies to...

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 reactance methods. This guide presents operating philosophy...

This standard covers certain mechanical requirements for liquid-immersed distribution transformers with respect to tank strength, as well as static and dynamic tank pressure mitigation. This standard can be applied to various tank configurations for distribution transformers. This...

Forward (This Foreword is not a part of ANSI/IEEE C57.117-1986, IEEE Guide for Reporting Failure Data for Power Transformers and Shunt Reactors on Electric Utility Power Systems.) The IEEE Transformer Reliability Working Group was formed in 1974 under the...

This standard is intended for use as a supplement to IEEE Std C57.13TM-2016 and as a basis for performance and safety of equipment.1 It also describes test sequences, criteria, methods, and documentation for tests. This standard applies to single-phase instrument transformers...

This standard prescribes insulation levels and dielectric test requirements for power transformers where: (1) The transformer insulation levels and dielectric test requirements are explicitly specified to be in accordance with this standard (2) The transformers are to be...

The intent of this guide is to assist the working groups within the IEEE Transformers Committee; thus, specific examples were taken from the transformer-related standards. It should be recognized that identification of general principles and procedures could have broader...

Foreword (This Foreword is not a part of American National Standard Requirements for Ventilated Dry-Type Distribution Transformers, 1 to 500 kVA, Single-phase, and 15 to 500 kVA, Three-phase, with High-Voltage 601 to 34 500 Volts, Low-Voltage 120 to 600 Volts, ANSI C57.12...

This guide for dry-type transformer through-fault current duration applies to dry-type distribution and power transformers built in accordance with IEEE Std C57.12.01™.1 Purpose This guide sets forth recommendations believed essential for the application of overcurrent...

This guide contains general and specific recommendations for grounding current and voltage transformer secondary circuits and cases of connected equipment. The practices recommended apply to all transformers of this type, including capacitive voltage transformers and linear...

This guide applies to transformers referenced in IEEE Std C57.12.00 as Categories I, II, III, and IV.1 It sets forth recommendations essential for the application of overcurrent protective devices applied to limit the exposure time of transformers to short-circuit currents (see...

This standard provides a basis for electronic reporting of transformer test data on liquid-immersed distribution transformers. This standard defines how to format and report the standard test data when electronic reporting is specified. In addition, it defines an extended set of data...

This part of IEC 60076 covers the requirements for phase-shifting transformers of all types. The scope excludes transformers with an unregulated phase shift. This document is limited to matters particular to phase-shifting transformers and does not include...

Foreword (This Foreword is not part of Amencan National Standard C57.12.55-1987.) The High Voltage Apparatus Coordinating Committee (HVACC) was established July 24, 1972 by the Electrical and Electronic Technical Advisory Board (now superseded by the Electrical and Electronic Standards Management...
