personal ground application on de-energized line
Please I need to get information about personal ground application while we working on de-energized transmission line as following example:-
1-if we replace insulator on structure # 10 phase A
-do we have to ground all phases or only phase A enough?.
-which tower should be grounded only Tower # 10 or before and after (9 and 11) ?
2- if we install repair sleeve in the middle of span, where the personal ground should be installed?
3- how we can install personal ground on OHGW?
Please I need any standard, drawing to be supported with reply...
Your help is highly appreciated
