Abstract: Standard terminal markings and connections are described for single-phase and three-
phase distribution, power, and regulating transformers. For terminal markings, it covers sequence
designation, external terminal designation, neutral terminal designation, grounded terminal
designation, and marking of full and tap winding terminals. Additive and subtractive polarity and
parallel transformer operation are described. Connections of single-phase transformers in various
configurations and angular displacement of three-phase transformers to connect to various system
phase displacements are covered.
Keywords: transformer connections, transformer terminals, transformer polarity
