How to calculate current of 10mva Dyn11 transformer. 110/kva to 6.6 kva.

 

3 Phase LINE Current = (kVA x 1000) / (line voltage x 1.732)

The primary is a DELTA so the primary phase current is primary line current / 1.732

The secondary is a WYE and the secondary phase current equals the secondary line current

I hope this helps,

Your Voltage rating is not properly mentioned?

Current = KVA / Voltage

DYn11 only effects the Phase shift Between Voltage of HV & LV Sides & Hence Currents.......
