Telegraph Pole Ground Wires-C&S

[Robert McFarland]

Check out "Telegraph C&S AlpineTunnel West Side" on the NGDF for a discussion on the use of ground wires.

South Park ought to be interested in this NGDF  topic by Linn Moedinger

Typical construction practice, especially in the high country.

I have many insulators used in the Front Range that show
flashover burns from lightning.

What about the comment of lightning starting firesin nearby depots?

[South Park]

Lightning is the electrical equivilent of dumping a million gallons of
water into a teacup all at once.  It overflows massively, anywhere it can
to find ground.  Wire heat up, against dry wood they start fires.  The
power surge is so great, it shatters the insulators closest to the strike
from inequal thermal expansion coefficients.  Poles catch fire.  It is a
basket of variables, but stuff is going to get really hot, really fast, and
bad ju-ju is going to follow.
