Two, 50 kVA, single phase transformers are connected in open delta bank supplying a balanced 3 phase load of 95 kVA at 0.866 pf lagging. Is the open delta bank overloaded? If so, find the minimum size in KVAR of a capacitor bank to be connected across the load to prevent the overloading of the transformers.
