Hello Dave, Actually, this is the preferred method for a single bushing pig. The case, the innermost primary turn on your Tesla Coil, and the bottom of your TC secondary winding should all be connected together and tied to your independent RF ground. Do NOT connect the case of the pig to your incoming power earth/ground. It's not necessary to do any modifications to your pig. You may want to elevate your HV lines off the floor to reduce corona. Your HV line has a bit of HV RF on it in addition to being ~15 kV RMS above ground, so corona is to be expected in your present configuration. Some coilers make 3-4" insulators using pieces of LDPE or HDPE (High Density Polyethylene) material to keep HV feedwires from the transformer off the ground. Ceramic standoff insulators (like those used to support bus bars in substations) also will work. Good luck and best regards, -- Bert --
: Hi, Is ( earth ground ) ok for the tank of a single bushing pig ? Its tied
: to the same ground as the coil. Im thinking a "floating " output
: (two bushing ) would be better ???its just me, this grounding thing has me
: in a tizzy : ( I could open the Xfrmer and disconnect the from the case
: and add another bushing, or maybe its not worth it.........I ran the coil
: and seems to work fine, although I set a safty gap at 3/8" -
: 1/2" and it would fire, Im running a static gap, so I thought it was
: safe to just eliminate it. The power feed line from my trans is on the
: concrete floor, and I can see corona glow . Its 15kv sign wire inside a
: glass tube, and still glows, is this the norm ???Thanks for all your help
: !!!!!!!!,dave
