asif Posted March 17, 2010 Report Share Posted March 17, 2010 Hi, Can anybody suggest me about selecting HT breaker for this case? The project is of a big mall here in Mumbai-India. The entire power is fed from three transformers of 2.5MVA each. Details of transformers : 2500KVA, 22kV/0.433kV, Dyn11, AN, Cast Resin Dry type. % impedance at 75deg : 6.25% Full load losses : 20KW We are to decide about the HT breaker for feeding these three transformers & it fault level. Can anybody guide me? If you need any more information, I'll try to furnish asap. Thanks. Asif Link to comment Share on other sites More sharing options...
