Analysis the wiring of a house circuit having fluorescent labs, incandescent lamp and a single phase motor is supplied from a 230 V, 50 Hz single-phase supply. The load details: (i) fluorescent lamps taking a current of 8 A at a power factor of 0.9 leading, (ii) incandescent lamps taking a current of 6 A at unity power factor, (iii) a motor taking a current of 12 A at a power factor of 0.65 lagging. Determine the total current taken from the supply and the overall power factor. Find also the value of a static capacitor connected in parallel with the loads to improve the overall power factor to 0.98 lagging. Illustrate the solution with relevant phasor diagram.
