The capacitances per Km of 3 core cable are 0.9 micro farad between the three bunched conductor and the sheath, and 0.4 micro farad between one conductor and the other two connected to the sheath. Draw the arrangement in each case and find:
a) the line to ground capacitance of a 20 Km cable length.
b) charging current if the cable operates at 11 KV line voltage at 50 HZ.
c) the power loss and loss angle if the power factor is 0.2 .
