A 100 MVA synchronous generator is connected to a 25kV infinite bus through two parallel transmission lines. The synchronous reactance of the generator is 2.5Ω, and the inductive reactance of each transmission line is 2Ω. The generator delivers 100 MVA to the infinite bus at 0.8 power factor lagging. Suppose a lightning strike causes one of the transmission lines to open. Assume that the mechanical power and excitation of the generator are unchanged. Can the generator still deliver the same amount of power to the infinite bus?
Determine the magnitude of the impedance in ohms for a 70mH inductor in series with a 15 ohm resistor. The frequency of excitation is 650 rad/s.
design an amplifier to sense the opencircuit output voltage of a transducer and to provide aproportional current through a load resistor. the equivelent sourceresistance of the transducer is specified to vary in the range of 1k to 10 k.
Suppose that we define the value of the complex constant A as A = -2 + 2j. Write the constant A in magnitude-angle form, that is, find |A| and A such that A = |A|ej A Sketch the real part of the function z(t), where z(t) = Aej(500pit+pi/2).
