Transformer	Permalink

Current Rating of Transformer = KVA x 1.4 Short Circuit Current of T.C /Generator = Current Rating / % Impedance No Load Current of Transformer =< 2% of Transformer Rated current Capacitor Current (Ic) = KVAR / 1.732xVolt (Phase-Phase) Typically the local utility provides transformers rated up to 500kVA For maximum connected load of 99kW, Typically the local utility provides transformers rated up to 1250kVA For maximum connected load of 150kW. The diversity they would apply to apartments is around 60% Maximum HT (11kV) connected load will be around 4.5MVA per circuit. 4No. earth pits per transformer (2No. for body and 2No. for neutral earthing), Clearances, approx.1000mm around TC allow for transformer movement for replacement. __________________ Henry Ford Coming together is a beginning.
