A three-phase transformer having a line voltage ratio of 0.4 kV/11kV is connected Star/Delta and protective transformers on the 0.4 kV side have a current ratio of 500/5. Calculate the ratio of the protective transformers on the 11 kV side. Draw a neat circuit diagram and indicate the given values at appropriate places.
