grounding



Original poster: "Matt T." <p2sarethebomb@xxxxxxxxxxx>


I am new to coiling and just recently finished my first coil and have run it successfully but have run into a few problems.

I am working on installing a RF ground, but ran my coil the first few times with no RF ground, just a ground strap left floating. It performed well producing 23 inch streamers( my coil is powered by a 15 kv 30 ma NST). Just last night i connected to the RF ground and went to power up. Every time I ran up my variac to only a few volts, my safety breaker poped. I disconnected from RF ground and the coil performed as before. My RF ground is completely separate from the house ground so i don't understand what is happening. My one concern is that i have the center tap of my NST connected to RF ground, but everything i have read says that is how it should be. I don't mind running it unconnected, but am concerned with safety. I am also wondering if my performance would be increased with it grounded. I appreciate your time and any comments.
