Question

Problem-1 [80 Points] A 4160 V three-phase feeder is shown in Figure. 1 The phase conductors are 4/0 ACSR and are configured on an 8 ft crossarm with phase spacings of:

Dab = 2.5', Dbc=4.5', and Dea = 7.0². a. Determine the series impedance of the line segment in 2/mile. b. Determine the Karop and Krise factors assuming a load power factor of 0.9 lagging. c. Determine the total percent voltage drop to node 6. d. Determine the three-phase kvar rating of a shunt capacitor to be placed at node 4 to limit the total percent voltage drop to node 6 to be 3.0%
