C57.105-2019/Cor 1-2023
IEEE Guide for Application of Transformer Connections in Three Phase Electrical Systems - Corrigendum 1
Transformer connections and configurations in three-phase electrical systems are described in this guide. The characteristics of the various transformer connections and possible operating problems under normal or abnormal conditions are treated. All combinations of delta and wye, grounded and ungrounded, T connected, zigzag, and certain special connections are considered. Only two-winding and auto-transformers are included.
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.
C57.105-1978
IEEE Guide for Application of Transformer Connections in Three-Phase Distribution Systems
The characteristics of the various transformer connections and possible operating problems under normal or abnormal conditions are treated for three-phase distribution systems. These systems are characterized by primary voltages up to and including 34.5 kV, usually have a preponderance of connected transformers with low-voltage windings below 1000 V, and furnish electric service to consumers. All combinations of Delta and Y, grounded and ungrounded, T connected, zigzag, and certain special connections are considered. Only two-winding transformers are included. Phasing procedures and loading practices are not 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No Inactive-Withdrawn Standards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
