This is true for many utilities. We've been putting this type od fiber
grd cable in for the past 10 or more years. But so far, we haven't done
any retrofits on older existing transmission lines.

I'm told that utilities are routinely pulling in topside protective
ground wires which have a fiber core. Someone in that industry might
comment. If true, they have the long-haul infrastructure...or will...
to make something like this play.
Agreed, and even longer for some utilities. I recall starting this in about
1986-87, nine yrs before I retired from Detroit Edison Co. 13.2kv
Y-distribution and 40kv subtransmission (then) mostly. There was idle talk
about it on
120kv, 230kv transmission but it sure wasnt done when I was there.
