Answer Posted / gunnam santosh
for an induction motor at starting current is very high
speed is small so initially reduced current is applied.for
star connected winding phase voltage is root3 times the line
voltage and for delta current is root3 times the line current
so initial current can be reduced by using delta and then
star during starting of the motor

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
