In a string of three identical suspension insulators units supporting a transmission line conductor, if the self-capacitance of each unit is denoted as ‘C’ farads, the capacitance of each connector pin to ground can be taken as 0.1 C farads. Determine the voltage distribution across the string, if the maximum permissible voltage per unit is given as 20 kV. Determine the string efficiency. Derive the formula used to calculate the string efficiency with a neat sketch where ever required
A three-phase overhead transmission line is being supported by three-disc suspension insulators; the potentials across the first and second insulator from the top are 8 kV and 11 kV respectively. Calcualte (i) the line voltage (ii) the ratio of capacitance between pin and earth to self capacitance of each unit (iii) the string efficiency
