A 500-hp, wye-connected, wound-rotor induction motor, when operated at rated voltage and frequency, develops its rated full-load output at a slip of 0.02; maximum torque of 2 times the full-load torque at a slip of 0.06, with a referred rotor current of 3 times that at full load; and 1.2 times the full-load torque at a slip of 0.2, with a referred rotor current of 4 times that at full load. Neglect rotational and stray-load losses. If the rotor-circuit resistance in all phases is increased to 5 times the original resistance, determine the following:
(a) The slip at which the motor will develop the same full-load torque.
(b) The total rotor-circuit copper loss at full-load torque.
(c) The horsepower output at full-load torque.
(d) The slip at maximum torque.
(e) The rotor current at maximum torque.
(f) The starting torque.
(g) The rotor current at starting.
Plug and Socket Condition : In the same way that your knowledge of flexes and fuses is wasted if you don't care to ensure that flexes and cables are routed safely and sensibly, so
