1) Each line of a 3-phase system given in figure is suspended by a string of 5 identical disks and the ratio of C₁/C-0.1 (Shunt capacitance per self-capacitance) is given. If the string is connected to line of voltage 33kV. a) What is the voltage distribution over the unit of string and what is the string efficiency? b) When the string is supplied by a Guard Ring and this lead to add a two air capacitance of value 0.2C, 0.1C respectively to the nearest to the conductor. Find the new voltage distribution and the new efficiency.
