Answer Posted / k.prakashchandra
% impedance( Say P )= I rated x Z x 100 /V rated. Hence Z =
P x Vr /Ir x 100. Fault current If = Vr /Z .Then If= Ir x100/P

a)In a 3-phase 4-wire circuit, a circuit breaker is selected to protect the circuit whose highest fault level is 6.6 MVA. Determine the required minimum breaking capacity in kA. (Note: Covert 3-phase power in terms of kA to find answer.) b)Using the below, determine the required minimum making capacity in kA as a “peak value”. Rate breaking capacity (Icn) ka: Icn<= 1.5 Factor = 1.41 1.5
