Question

A 10 kW, 400 V, 3 phase induction motor is started with direct on line starter. The motor current and power factor at starting will be _______ respectively
1. 20 A, 0.2
2. 20 A, 0.6
3. 120 A, 0.6
4. 120 A, 0.2

Answer 1

Correct Answer - Option 4 : 120 A, 0.2

At starting the motor current is 5 to 8 times of full load current. The power factor at starting is very less. Hence the option (4) is correct.
