In a 3-phase overhead system, each line is suspended by a string of 3 insulators. The voltage across the top unit (i.e. near the tower) and middle unit are 10 kV and 11 kV respectively. Calculate (i) the ratio of shunt capacitance to self capacitance of each insulator, (ii) the string efficiency and (iii) line voltage
