09. A single phase, 100 V.50 Hz source supplies a single phase load having impedance of 109 and power factor .8 (lag) through a line of impedance Zline = (2+36) N, as shown in Figure 9. A pure capacitor is connected Parallel (shunt) with the load. Two volt me ters, V, and V2, are connected at the source and load ter minals bectively as shown in the same figure. (a) Find the minimum value of the capacitance (Csh) such that the readings of the two volt meters are exactly e. Find the load current (IL) and the source current (Is) under this condition. 3
(b) Taking the source voltage as the reference, draw a phasor diagram showing the load terminal voltage current, load current and the current into the capacitor (Ic). ans. (a) C = 381.972 pF. I_ = 1020° A. Is = 10273.73° A; (b) Lc = 12253.13º A | 1-4, 1009, 50Hz Z = (2+j6) 1 CA 1-6 load, 109. 0.8pf (lag) Figure 9: Question 9
