Existing Standards	Superseded IEEE C57.105-1978 - IEEE Guide for Application of Transformer Connections in Three-Phase Distribution Systems The characteristics of the various transformer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.
	Active IEEE C57.105-2019 - IEEE Guide for Application of Transformer Connections in Three-Phase Electrical Systems Descriptions of products, methods, and procedures relating to stationary batteries, battery electrolyte spill mechanisms, electrolyte containment and control methodologies, and firefighting considerations are provided.
