Three-phase electric power - Wikipedia
Three-phase electric power is a common method of alternating current electric power generation, transmission, and distribution. It is a type of polyphase system and is the most common method used by electrical grids worldwide to transfer power. It is also used to power large motors and other heavy loads. A three-wire three-phase circuit is usually more economical than an equivalent two-wire
Easy understanding of 3-phase transformer connections
Three-phase voltage transformations can be accomplished by using three phase transformers, which are single devices with all windings constructed on a single iron core. They also can be accomplished by using three single-phase transformers that are connected externally to form a three-phase bank

How to Wire a 3 Phase Motor Starter | Hunker
Three-phase electric motors use three different electric legs with a 1/3-cycle lag between them. To use three-phase electricity, a motor needs windings spaced 120 degrees apart.
Instrument transformer - Wikipedia
Current transformers (CT) are a series connected type of instrument transformer. They are designed to present negligible load to the supply being measured and have an accurate current ratio and phase relationship to enable accurate secondary connected metering.[PDF]
