A 2200-V, 1000-hp, three-phase, 60-Hz, 16-pole, wye-connected, wound-rotor induction motor is connected to a 2200-V, three-phase, 60-Hz bus that is supplied by synchronous generators. The per-phase equivalent circuit of has the following parameters: R1 = 0.1 = R 2, Xl1 = 0.625 = X l2, and Xm = 20 .Ifthe machine is driven at a speed of 459 r/min to act as a generator of real power, find the rotor current referred to the stator and the real and reactive power outputs of the induction machine.
Q. Sketch the asymptotic Bode plots for the following loop-gain functions, and find the approximate values of gain and phase margins in each case.
A dc shunt motor runs off a constant 200-V supply. The armaturewinding resistance is 0.4, and the ?eld winding resistance is 100 . When the motor develops rated torque, it draws
Considering the TTL NAND gate circuit of Figure, with one or more inputs low, show that the output will be high.
Personal safety Power supplies can be very dangerous. This is specifically true of high voltage circuits, but anything over 12 V must be treated as lethal potentially. A po
