Discussion on “potential stresses as affected by overhead grounded conductors,” at Chicago, May 24, 1907

I consider Mr. Jackson´s paper an interesting discussion of a very important topic. It is, as Mr. Jackson admits, purely a theoretical discussion of the amount of protection which may be expected from an overhead grounded wire. Many transmission line operators believe that this overhead grounded wire has no virtue; others believe that it has a great deal of virtue. I expect that there are representatives of both camps present and I hope the discussion will be complete.
