This guide describes transformer connections and configurations in three-phase electrical systems, the characteristics of these various connections, and the possible operating problems under normal or abnormal conditions. All combinations of delta and wye, grounded and...

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 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 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 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...

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 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...

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...
