Problem related to lightning stirke in 132 kV double circuit
(OP)
Hi
I was asked what I will do if there are a number of lightning strikes in a double circuit transmission line of 132 kV. How can this problem can be dealt with ?
Could any body suggest the solution to this problem ?

I said if we can modify the tower then we should increase the shielding angle by changing slightly the tower configuration assuming other things are fine. I wanted to know what may be the possible problems and what can be the possible solution.

You have to study your particular installation and make your own determinations. Those answers would be appropriate for that location, but might not even apply elsewhere on your system.
For me and my system, lightning is so rare that it doesn't make sense to worry about it. In Florida lightning caused misoperations are so common that they'll reclose once on bus diff trips. Again, no one right answer.

In the question , I was asked more about lightning only which I was least bothered . But it was a kind of time when I had to answer . I am not sure whether my answer convinced him or not ?
But still I wanted to know what are the possible casues and solution to this problem even though we need to study for specific reason. Please be kind to elaborate the problem
regards

You can also put in some distribution under-build on the transmission towers. Since the distribution insulators are much shorter than the 132 kV insulators, the lightning will flash over to the distribution line and save the transmission line. This will make your distribution customers very mad as their transformers will explode and put them in the dark and possible damage their electronics.

1. reduce the tower resistance and
2. we can put lightning arrester in one of the circuit.

Of course the arrester vendor will tell you that they will protect the line and happily sell you lots of arresters.
