The following phase schematic diagram (FIGURE 4) shows an 11 kV, 50 Hz, 3-phase, short line feeding a load. By calculation or constructing the phasor diagram (use a scale of 1 mm = 2 A) for the load current with VR 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.
