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.
Classify the conducting materials. Conducting materials are classified by low resistivity materials and high resistivity materials. Low resistivity materials: The conduct
Q. A dc shunt machine has an armature winding resistance of 0.12 and a shunt-?eld winding resistance of 50 . The machine may be run on 250-V mains as either a generator or a mot
Q. J and K are the external inputs to the JKFF shown in Figure. Note that gates 1 and 2 are enabled only when the clock pulse is high. Consider the four cases of operation and expl
Q. What do you mean by sub address? A sub address, though a part of the ISDN address, isn't considered as an integral part of the numbering scheme. Sub address is carried in a
Q. For the electromagnet shown in Figure, the λ-i relationship for the normalworking range is given by i = aλ 2 + bλ(x -d) 2 ,where a and b are constants. Determine the force app
Write Some Notes for the Gauss-Seidel Method? 1. Equation below is used to calculate the voltage at each busbar in turn, always using the most up to date values for the other
Q. Determine the Thevenin resistance viewed from terminals A-B of the circuit of Figure by setting independent sources to be zero and applying a test voltage at terminals A-B.
Q What do you mean by Direct coupling? In this method the a.c. output signal is fed directly to the next stage. No reactance is included in this coupling network. Special d.c.
Q. What are the performance measures of oscillator circuits? 1. Stability: This is determined by the passive components. R, C and L determine frequency of oscillations. If R ch
