[TowerTalk] Ground Resistance

[Travis W. Pederson]

The instrument is called a Megger, and there is a writeup here on ground
resistance measurements:

Way, yes... simple, not really.  There are meters made for measuring ground
system resistance, but they rely on either a very good reference ground
nearby, or a couple of rods spaced the right distances apart to act as a
reference.  Its been some years since I used one so I forget the exact
process, but its spelled out in detail in the manuals.  The one I used last
was made by Biddle if I remember correctly.  Check with a local electrician
or electric company crew, they may have one and could make the measurements
for you.  Or the meters can be rented from electronic rental places if you
want to do it yourself.
