·Insulators are a vital part in transmission system they held the overhead transmission line and provide a mechanical support besides they act as an electrical insulator to insulate the line from the supporting system ( pole, tower...etc.)
·If you have a 33 kV overhead line, there are three units in the string of insulators.If the capacitance between each insulator pin and earth is 11% of self-capacitance of each insulator.
