How would I determine the surge point on a transmission line. I.e. if a lightning stroke hit an overhead transmission line?

 

Perhaps you could elaborate on the meaning of your question. It doesn't make sense to me.

 

Sorry if it is a bit vague. I have to describe how I would accurately define the surge point over a wide range of changing conditions? This is the question word for word. I am unsure of its descriptive meaning also as it does seem rather vague to me. If anyone understands the requirement then please let me know.

Kind regards

 

Googling "surge point", I don't find anything about transmission lines. Do you know what "surge point" means?

 

You might be able to find a section of the HV line isolated with breakers blown due to the lightning surge.
