Determine the line currents as well as the phase or load voltages in the given circuit. а Ta A 440/0° V (+ 6- j8 2 N 6- j8 2 6- j8 2 440/120° V (+ 440-120° V

2-What is the relationship between phase and line quantities in balanced star and delta connections in three phase circuit balanced ? Why?

For a star connected three phase AC circuit is associated with

A load impedance, Zo = 10 + j 3 ohm, is connected to a source with line resistance equal to 3 ohm, as shown in the figure.  Determine the apparent power supplied by the generator. The apparent power supplied by the generator is _____ VA.

For a 3-phase ac device, full load current is 50A, line voltage is 400V and reactance value is 0.040, then percentage reactance of this device is O 0.5 % O 0.288 % on O 4% O 0.866 % In a power system the short circuit current due to symmetrical fault occurred near to generating station is calculated as 6000A then, if the symmetrical fault occurred away from generating station then short circuit current may be 8000A O 10000A O 12000A O 3000A Next pa
