The load current in a system is 100 A. the short-circuit current for the smallest fault is 100 A. An overcurrent capable of carrying a current of 5 A continuously is to be used. (a) Suggest a suitable C.T. ratio (b) What will be the current for the smallest fault? (c) Will the protective C.T be able to faithfully reproduce the fault current?
