Hey John...
Since you are imploying a 9/30 NST as the power supply, you have a few
options as far as grounding. In preferential order here they are
1. ( expensive) pound about 10 8' copper rods into your lawn and
connect all of them together with 1/2" thick solid core copper wire :)~
Not only expensive, but sort of massive overkill... On the other hand,
if your coil magically calls down lightning strikes, then you're all set.
2. ( affordable) drive 1 8' copper clad steel rod into the ground and
connect with 12 ga. wire
For a 9/30? How long is that 12ga wire? Unless the ground rod is right
underneath the coil, I don't know that this is much better than just
laying the wire on the ground, sans rod.
3. ( cheaper) drive 2' of steel pipe with 12 ga. wire attached
4. (really cheap) use a counterpoise made of chicken wire approximately
3X3 feet attached to the base of the secondary with 10 ga. wire
You might go to 4x4 ft.. and AWG 16 wire is a lot easier to handle, and
will certainly handle the not too massive current from a 9/30 (after
all, the RMS current in the PRIMARY is 30mA, tops, and the RMS current
in the secondary is probably less than 1 mA. Peak currents are higher,
sure, but the secondary is wound with a good fraction of a mile of
fairly fine wire, so the extra loss from a couple feet of AWG 16 as
opposed to AWG 10 is negligible.
5. ( really cheap now) spread alot of salt on the living room carpet and
soak well with water, attach wire to plumbing or gas pipe and lay wire
on carpet or better yet in soaking wet carpet pad... not the best idea
but possible with potential dangers involved ( do not touch toroid while
barefoot on the wet carpet if using this method)......
Or, invite a crew of incontinent beer drinkers over and get a barrel of
beer...
Or all the puppies from 101 Dalmatians? (prior to house training)
6. dont ground at all but be prepared for transformer/cap failure or
racing arcs on the secondary...
Oh yeah.. an excellent way to kill your NST, if the secondary doesn't
catch fire first..
been there, done that..
