A 22kV, 50 Hz overhead transmission line connects Ibra and Muscat. There are three units in a string of insulators. If the capacitance between each insulator pin and earth is 13% of self-capacitance of each insulator, Calculate: i. Distribution of voltage over 3 insulators ii. String efficiency iii. Draw a suitable figure for this problem and mark the self-capacitance, capacitance between pin and earth, voltages and currents. iv. Calculate the new string efficiency if the third insulator which is near the conductor is removed.
