10.33 The steady-state voltage drop between the load and the sending end of the line seen in Fig. P10.33 is excessive. A capacitor is placed in parallel with the 150 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, 4800 V (rms). The 150 kVA load is operating at a pow- er factor of 0.8 lag. Calculate the size of the capacitor in microfarads if the circuit is operating at 60 Hz. In selecting the capacitor, keep in mind the need to keep the power loss in the line at a reasonable level. Figure P10.33 V 10 Q2 j5 Q 4800/0° V (rms) 150 kVA 0.8 lag

Transcribed Image Text:10.33 The steady-state voltage drop between the load and
the sending end of the line seen in Fig. P10.33 is
excessive. A capacitor is placed in parallel with the
150 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,
4800 V (rms). The 150 kVA load is operating at a pow-
er factor of 0.8 lag. Calculate the size of the capacitor
in microfarads if the circuit is operating at 60 Hz. In
selecting the capacitor, keep in mind the need to keep
the power loss in the line at a reasonable level.
