transformer bank
1.The conclusion is that it is suitable to select HV vacuum contactor——current limiting fuse combined electric apparatus in 1 600 kVA and the below transformer circuit, 1 200 kW and the below HV motor circuit and 1 200 kVAR and the below capacitor bank.
2.The installed capacity of generators in Three Gorges Project Left Bank Powerhouse is very large?so the acylic component caused by the short circuit faults will make a very bad influence to busbar protection．Based on this case?the issues? such as the maloperation of busbar protection caused by saturated CT and ratio difference current of transformer of busbar CT?should be considered when making the selection for busbar protection．
