1. A 3-phase transmission line is being supported by three-disc insulators. The potentials across top unit (i.e., near to the tower) and middle unit are 8 kV and 11 kV respectively. Calculate (i) the ratio of capacitance between pin and earth to the self-capacitance of each unit (ii)the line voltage and (iii) string efficiency. Hints : 12 = I1 +ii, V20 C = V, 0 C +V, KOC = KC HE i1 A* 12 KC HH C iz ? B 13 KC HH iz
