Star-Delta Transformer | Electrical Devices | Electrical Engineering
In a star-star or delta-delta 3-phase transformer there is no phase shift between the corresponding voltages of any phase to neutral on either side. However, a delta-connected winding is desirable in many power transformers for reasons of harmonic elimination. As such most of the power transformers are either star-delta or delta-star connected. In such transformers, even under normal operating condition, [...]
