In a 5 insulator disc, string capacitance between each unit and earth ...
To solve this problem, we can use the concept of capacitance and voltage division.

Let C be the mutual capacitance between two adjacent units and C/6 be the capacitance between each unit and earth. Let the voltage applied across the entire disc be V.

The total capacitance between the middle unit and earth is 2*(C/6) = C/3 (since there are two units on either side). The total capacitance between the middle unit and the adjacent units is 2C.

Using voltage division, the voltage across the middle unit can be calculated as:

V_middle = (C/3) / (2C + C/3) * V

V_middle = 1/7 * V

Therefore, the voltage across the middle unit is 1/7th of the voltage applied, or approximately 14.3% of the voltage applied.

In a 5 insulator disc, string capacitance between each unit and earth ...
In a five insulator disc string capacitance between each unit and earth is 1/5 of the 
mutual capacitance. Find the voltage distribution across each insulator in the string 
as percentage of voltage of the conductor to earth, find the string efficiency and 
how the efficiency is affected by rain? If the insulators in the string are designed 
each to with stand 35 kV maximum, find the operating voltage of the line where 
five insulators string can be used
