IEEE Power Transformer Standards

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 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,...

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...

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 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 standard describes electrical and mechanical requirements of liquid-immersed, single- and threephase, step-voltage regulators, not exceeding a regulation of 3000 kVA (for three-phase units) or 1000 kVA (for single-phase units). This standard does not apply to load tap-changing power...

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...

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...

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...

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 matters relating to...

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...

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...

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...

This Guide provides general and specific recommendations on application of step-up and step-down liquid-immersed and dry type transformers in DPV Power Generation Systems for commercial, industrial and utility systems. The Guide focuses mainly on the inverter transformers of...

This guide provides general and specific recommendations on application of step-up and step-down liquid-immersed and dry-type transformers in distributed photovoltaic (DPV) power generation systems for commercial, industrial, and utility systems. The guide focuses mainly on the...

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...

This guide addresses the application of tertiary and stabilizing windings in liquid-immersed power transformers, as covered by IEEE Std C57.12.00, as well as recommendations to evaluate the need or convenience of having such windings. The primary application of this guide is...
