Pilot wire system

[HighPotter]

I'm looking for information on the installation and maintenance of a electric utility pilot wire system, between substation.Is there data out there explaining the system, and trouble shooting?

Thanks

The relay books by Blackburn and Elmore would be good places to start.

The Areva NPAG referenced numerous times in Eng-Tips is another.
