Arching rings on 400kV overhead lines
Arching rings on 400kV overhead lines
(OP)
Dear all. I want to place my question about the installation of arching rings on 400kV overhead lines. These rings are supposed to carry any transient overvoltage and try to break the air gap so they should be placed in the lower length between the live terminal and the earth. Can you give some pictures of these rings installation? On site the installation of the arching rings on the tension insulators are misplaced and as another result the chambers are fastened upside down.

You might do better in your search if you take the 'h' out of arc(h)ing.

It seems that the corona rings are towards the insulators strings and not towards the active line as it happens on our site.
