Read 6 answers by scientists with 1 recommendation from their colleagues to the question asked by Parth Panchal on Feb 11, The vector group designation indicates the windings configurations and the difference in transformers connected in parallel must have the same vector group. The Dyn winding vector groups do not allow zero sequence currents (commonly known as earth fault current) to pass across the transformer. Thus, the yn side of.

What is meant by vector group for transformers and why is it important?

Thanking sir K Mohana Krishna. The vector group provides a simple way of indicating how the connections of a transformer are arranged. This means that a 3-phase transformer can have its primary and secondary windings connected the same delta-delta or star-staror differently delta-star or star-delta. Your electrical notes are very very helpful.
