series impedance

The three loads in Problem 10.28 are fed from a line having a series impedance  as shown in Fig. P10.29.

a) Calculate the rms value of the voltage ()at the sending end of the line.

b) Calculate the average and reactive powers associated with the line impedance.

c) Calculate the average and reactive powers at the sending end of the line

d) Calculate the efficiency of the line if the efficiency is defined as

Problem 10.28

Three loads are connected in parallel across a 300 V(rms) line, as shown in Fig. P10.28. Load 1 absorbs 3 kW at unity power factor; Load 2 absorbs 5 kVA at 0.8 leading; Load 3 absorbs 5 kW and delivers 6 kvars. a) Find the impedance that is equivalent to the three parallel loads.

b) Find the power factor of the equivalent load as seen from the line’s input terminals.
