calculate external resistance values to add to the rotor of a slip ring induction motor. STATOR- 415 V, 3 phase delta, 1100 A, 50 Hz, 1490 rpm, pf 0,86 ROTOR - 660 V, 590 A, 50 Hz. STATOR current at each steps STEP1-600A,STEP2- 800A,STEP3-1000A,STEP4-1100A.

IF TVM OF TRANSFORMER SHOWS POWER FACTOR ON 33 KV SIDE AS 0.97 LAGGING AND ON 132 KV SIDE IS 0.75 LEADING.IS THIS CORRECT.WHERE IS PROBLEM.
