three phase transformer connections and basics

Three Phase Transformer Connections and Basics

The three-limb core-type three-phase transformer is the most common method of three-phase transformer construction allowing the phases to be magnetically linked. Flux of each limb uses the other two limbs for its return path with the three magnetic flux’s in the core generated by the line voltages differing in time-phase …

distribution transformer - wikipedia

Distribution transformer - Wikipedia

A single phase delta transformer has two bushings on top which are connected to two of the three primary wires, so the voltage across the primary winding is the phase-to-phase voltage. A disadvantage of a delta transformer is if only one of the two primary phases is deenergized, the remaining phase will backfeed through the transformer winding ...

January 24, 1996 - Levine Lectronics and Lectric

Ground faults on the transformer secondary are seen as ground faults on the primary since the zero sequence (neutral) current passes directly through the transformer, making relay protection difficult. With a delta-wye transformer, the secondary ground faults do not cause zero sequence current to flow in the primary circuit.
