Consider the two industrial loads that are connected to the source as shown in Figure. We would like design a compensation system to correct the power factor as seen from the source. The Source and the feed line between the source and 40kW source is not accessible, but the feed line between the loads is in the factory, although it is fixed (you can not change it). The voltage across the 18kW load must be kept constant at 220V(rms). (a) Calculate the value of Vs, without compensation. (b) How must we connect the compensation capacitor(s) to the system? Possible choices are: Between the terminals of i. the source, ii. the 40kW load, iii. the 18kW load, iv. both loads, v. the source and both loads Justify your answer. (c) We want to set the power factor of the source to 0.96 (lagging). Calculate the impedance of the capacitor(s) required, according to choice you made in part (b). The frequency of the operation is 50HZ

(a) Calculate the value of Vs, without compensation.
(b) How must we connect the compensation capacitor(s) to the system? Possible choices are:
Between the terminals of
i. the source,
ii. the 40kW load,
iii. the 18kW load,
iv. both loads,
v. the source and both loads
Justify your answer.
(c) We want to set the power factor of the source to 0.96 (lagging). Calculate the impedance
of the capacitor(s) required, according to choice you made in part (b). The frequency of
the operation is 50HZ
