Three single phase two winding transformers, each rated 400MVA, 13.8/199.2kV, with leakage reactance Xeq=0.10PU, are connected to form a three phase bank. The high voltage windings are connected in Y. A three phase load is connected on the high side and operates at 1000MVA, 0.9 lagging PF with Van=199.2kV. Determine the Van on the low voltage side if the windings are connected in a Y.
