What is Anemometer used to measure?
how to calculation increase capacitor,increase power factor for three phase.
What is the necessary condition for stability.
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.
