Evaluate the following parameters for a star connected 3 phase balanced load consisting of a resistance and capacitance in series in each phase when connected across a 440 V, 50 Hz supply. Readings of the wattmeters used for power measurement in two Wattmeter method are 810 W and 2100 W. a) The power factor of the circuit. b) The line current. c) Capacitance of each capacitor.
Evaluate the following parameters for a coil connected in series with a pure resistor of 300 connected across a 240 V, 50 Hz supply. Voltage across the coll is 180 V and that across the pure resistance is 130 V. a) The power consumed by the coil. b) The coil resistance and inductance. c) Power factor of the circuit.
