Voltage Distribution Over Suspension Insulator

This video is about voltage distribution across the discs of suspension insulators & string efficiency. The voltage is not uniformly distributed across the discs of the suspension insulator. The disc nearest to the conductor has a maximum voltage across it. As we move towards the cross-arm, the voltage across each disc goes on decreasing. Therefore, the unit nearest to the conductor is under maximum electrical stress and is likely to be punctured. To avoid this, we need a more uniform distribution of voltage. This is usually expressed in terms of string efficiency.

Nice video

Thank you 😊

[@everythingyouneed1392]

clear explanation of concept.
my question:
how will the charging current be distributed among shunt capacitances.
why do we use metalic link between insulators, can't a non metalic link would have resolved the issue.

[@TheLearningCurveBenila]

The shunt currents are ib and ic. From 04:20, we can understand that ib is proportional to Vb and ic is proportional to Vc. From 04:40, its clear that Vc = V3 and Vb = V3 + V2 . This means ib should be greater than ic.
Insulator discs are heavy. Similarly, the powerlines that hang from the insulator are also heavy. Therefore, the links should be very strong to hold these heavy things. We cannot compromise with the strength. So, I think metals play a good role here.
Please let me know if you still have any more doubts.
