22 A consumer is supplied at 380V 3 phase from a 11 kV substation through a 1500 kVA 11kV/380V transformer and a 380V cable as shown in Fig. Q2. An overcurrent relay supplied through a 3000/5 C.T. is installed at the low voltage side of the transformer t protect the cable and the consumer. The fault level of the 11kV substation is 250 MVA The impedance of the transformer and the 380V cable are shown in Fig. Q2. i) Calculate the maximum fault current which the relay will be expected to measure fo any type of fault in the 380V system. 1500 KVA 11KV/380 V 3000/5 MVAse 250 MVA 1x₁-x₂=X₂-5% 2₁-2₂ -0.005 +10.005 Zo-0.01 +10.005 380 V I
