Question
The two loads in the circuit shown can be described as follows: Load 1 absorbs 8 kW at a leading power factor of 0.8. Load 2 absorbs 20
kVA at a lagging power factor of 0.6.
1. Determine the power factor of the two loads in parallel.
2. Determine the apparent power required to supply the loads, the
magnitude of the current, Is, and the average power loss in thetransmission line.
3. Given that the frequency of the source is 60 Hz, compute the value of
the capacitor that would correct the power factor to 1 if placed in
parallel with the two loads. Recalculate the values in (b) for the load
with the corrected power factor.

- The steady-state voltage drop between the load and the sending end of the line seen in (Figure 1) is excessive Suppose that V-4950/0° V (rms). A capacitor is placed in parallel with the 192 kVA load and is adjusted until the steady-state voltage at the sending end of the line has the same magnitude as the voltage at the load end, that is, 4950 V (rms). The 192 kVA load is operating at a power factor of 0.8 lag. Part A Calculate the size of the capacitor in microfarads if the circuit is operating at 60 Hz. In selecting the capacitance, use the value that results in the lowest possible power loss in the line.
