(OP)
Any suggestion for finding operation/maintenance manuals for old Kelman and ITE, medium voltage oil circuit breakers? Mostly circa 1950-1970

RE: Kelman and ITE OCB manuals
As for Kelman, I have no idea.

Agree on the low voltage gear, but I believe the high voltage side went first to Westinghouse, then ABB.
Check with ABB Power T&D Services.

The Kelman breakers are original, and have never been retrofitted. (alot of the breakers from that era have been). I'm going to start calling some other utility's that might have these CB's still in service.
