Dyn vector group
WebA three-phase 1250 kVA, 22/0.400 kV, 50 Hz transformer with connection delta-star, vector group Dyn 11, is to be connected in parallel with a 3-phase transformer with similar rating, frequency and transformation ratio. The two transformers are energized from the HV side (symmetrical 3-phase system) but are running with open-circuit on the LV side. WebThis video explains how does phase shift occur in three phase transformers in commonly available vector groups and how we can identify it from the name plate...
