Power Factor
The phase schematic diagram in the attachment, shows an 11 kV, 50 Hz, 3-phase, short line feeding a load. By constructing the phasor diagram (use a scale of 1 mm = 2 A) for the load current with V_R as reference, determine the capacitive current and
* calculate the capacitive reactance/ph such that the load power factor is increased to 0.98 lag,
* calculate the percentage reduction in line current with this value of capacitive reactance in circuit.
