Can u explain : what is supply for train (whether a,c or d.c
).I know that supply is 25000v a.c .But there is rumour that
supply is D.C.
And also explain how lights and fans inside the trains are
working ,and what type of motors are used in trains whether
D.C motors or induction motors .If d.c motor, how it gets
supply.If traction motors are used then what are traction

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
