The distribution of voltage over 3 insulators and String efficiency is 85.74%.
Step-by-step explanation:
Given:
The string of insulators in an OH line is made up of three pieces.
The capacitance between each insulator pin and earth is 11%.
To find:
The distribution of voltage over 3 insulators and String efficiency.
Solution:
Step 1:
The voltage across each insulator is
⇒
Let us assume that
Apply at node
Therefore,
And,
Step 2:
From the equation (1)
If we considered the distribution of voltage over 3 insulators
then,
Step 3:
String efficiency
%
As a result, the voltage distribution over three insulators and the string efficiency is 85.74 percent.
