A100 kva, 20 kv synchronous generator is connected through a transmission line to a 100 mva, 20kv synchronous motor. the per unit transient reactances of the generator and motor are 0.25 and 0.20 respectively. the line reactance on the base of 100 mva is 0.1 per unit. the motor is taking 50 mw at 0.8 power factor leading at a terminal voltage of 20 kv. a three-phase short circuit occurs at the generator terminals. determine the transient currents in each of the two machines and in the short circuit. what is the magnitude of the current in p. u. before the short circuit occurs?

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc
