Question

Consider the situation shown in (Figure 1). A 1000-V-rms source delivers power to a load. The load consumes 140 kW with a power factor of 55 percent lagging. Time remaining: 00:07:30 Electrical Engineering Consider the situation shown in (Figure 1). A 1000-V-rms source delivers power to a load. The load consumes 140 kW with a power factor of 55 percent lagging. 1- Find the phasor II, assuming that the capacitor is not connected to the circuit. Enter your answer using polar notation. Express argument in degrees. 2-Find the value of the capacitance that must be connected in parallel with the load to achieve a power factor of 100 percent. Express your answer to three significant figures and include the appropriate units. 3-Usually, power-systems engineers rate capacitances used for power-factor correction in terms of their reactive power rating. What is the rating of this capacitance in kVAR? Express your answer using three significant figures. 4-Assuming that this capacitance is connected, find the new value for the phasor I. Enter your answer using polar notation. Express argument in degrees.
