b) At Islington substation, three transformers connect the 220kV busbar to the 66kV busbar. Each transformer is continuously rated at 200MVA, and has a leakage reactance of 8%. If the 220kV winding tap changer on one transformer is stuck at 0%, and the other two are set at +2.5%, calculate the effect on the transformer MVA loading.
