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.
Crossovers are generally used with loudspeakers having multiple drivers. Loudspeakers with single drivers are unable to cover the entire frequency range i.e from low to high freque
Q. An elementary two-pole rotating machine with uniform air gap, as shown in Figure, has a stator-winding self-inductance Lss of 50 mH, a rotor-winding self-inductance Lrr of 50 mH
Q. Counting to moduli other than 2 n is a frequent requirement, the most common being to count through the binary-coded decimal (BCD) 8421 sequence. All that is required is a four
Q. The block diagram of Figure represents a multi loop control system. (a) Determine the transfer function C(s)/R(s). (b) For G 2 G 3 H 2 = 1, evaluate C(s)/R(s).
Define Shunt VAr Compensation? Shunt capacitors absorb leading VArs (i.e. they are used to supply lagging VArs) whereas reactors are used to absorbs lagging VArs. Capacitors an
The conveyor system is driven by a 240 Volt 50 Hz AC motor requiring a continuous 1 Amp supply. The conveyor has single direction operation. The loading mechanism for the winder
