Each phase of a three-phase, delta-connected motor has a resistance of 15  and an inductance of 0,02 H. The motor has an efficiency of 77 %. It is supplied by a star-connected alternator having a phase voltage 220V at 50 Hz. Draw a complete circuit diagram. Calculate the motor phase currents and the motor output power. Also calculate the capacitance required to improve the power factor to 0, 93 lagging.
