Subject: [TCML] Safely Grounding a Tesla Coil
Hi all,
I know that it's said that you need an entirely seperate ground rod when
opperating tesla coils because the high voltage grounding through the
house wiring is extremely dangerous to anything plugged into any other
grounded outlet on the same circuit. But what if you attached the coils
ground wire directly to the ground rod. It would be bypassing the house
wiring, so the high voltage won't be running by any precious electronics
inside the house. It shouldn't be running back up into the house right?
I'm trying to be minimalistic so I don't have to try to pound down a
ground rod of my own.
Thanks,
Brandon
It made a big difference when I sunk a new ground rod in my yard. Even when
the coil is not firing except for the spark gap, there is very little RF in
my house (speakers on the TV). Fortunately for me, though, the transformer
for the buried power lines in my neighborhood is in my front yard, about 60
feet from my ground rod. I isolated the RF and power supply ground
completely in my coil to alleviate any ground loops. I think it makes for a
better spark, but the coil will still run without any ground connection
whatsoever (oops, that did make some noise on the speakers! My wife
informed me of that).
