Dy5 transformer connection
WebAnswer / kobena wiredu. DYn means a delta-star connected transformer in which the primary is delta connected and the secondary is star connected. The number that follows tells us the position of the Red phase of secondary relative to the primary using the clock (primary Red phase at 12oclock).So Dyn11 means secondary is on the 11 oclock line … WebLiked by Daniel Tolessa.
