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,...

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...

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...

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 recommended practice applies only to two winding transformers covered by IEEE Std C57.12.00, IEEE Std C57.12.01, and NEMA ST20.1 It does not apply to rectifier transformers.2 Purpose The purpose of this document is to establish uniform methods for determining the...

This guide sets forth characteristics of ventilated dry-type transformers relating to performance, limited electrical and mechanical interchangeability, as well as recommended practice for installation of the equipment described, and to assist in the proper selection of such equipment....

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 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 transformers having two, three or multiple windings....

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 covers electrical, dimensional, and related requirements for outdoor power apparatus bushings that have basic impulse insulation levels (BILs) of 150 kV and above. It provides specific values for dimensional and related requirements that are to be interpreted, measured, or tested in...

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,...

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 transformers having two,...

This standard describes methods for performing tests specified in IEEE Std C.57.12.01 and other referenced standards applicable to dry-type distribution and power transformers, with a voltage of 601 V or higher in the highest voltage winding.2 It is intended for use as a basis for...

This standard covers design, manufacturing, and testing unique to the application of power rectifier transformers intended to operate in dc supplied transportation substation applications up to 1500 V dc nominal output. Purpose At the present time there are no suitable standards governing...

Foreword (This Foreword is not a part of IEEE C57.111-1989, IEEE Guide for Acceptance of Silicone Insulating Fluid and Its Maintenance in Transformers.) This guide was prepared by the Insulating Fluids Subcommittee of the Transformers Committee of the IEEE Power...
