Re: [TCML] NST and HV Cables
Hi,
I have used a 10Kv 100mA Fart with it's GFI disabled and protected with a Terry filter to great effect. A word of warning, I destroyed an earlier identical (new) transformer by flicking it on and off at max voltage across a spark gap with nothing else connected so beware back EMF effects.

Bimmy: Pour yourself a drink, sit down and relax, and re-read my post again,
Rixong: Yes it appears to be a heavy iron type even though it looks like a
new type electronic one. The trouble though is that the sensors for earth
leakage and open-circuit protection will cause problems. Now, if you can
actually disconnect them it would be ok, but a lot that look like that have
the parts buried inside the resin, the FART one you have fortunately didn't.
Later resin filled ones without the protection circuitry, could be better in
some respects, as a modern resin would be better than old fashioned tar of
course, which may have voids in it. Tar is also
probably a worse insulator
than modern resin.
I used four 10Kv FARTS the same as yours in parallel for quite a while
before getting a pig.

Hello Phil and group,
Say Phil, just curious how you came up
with the 10KV value. Looking at the nameplate under KV I see 3,75-3,75 and
that leads me to believe it is a 7,500 volt 60 MA output not 10/60. From
what I have read it will work,not the best and hard on the spark
gap but it
is doable. I wonder tho ,if a voltage doubler would work in this
circumstance. I have at least one 750/120 and wanted a simpler demo version
so I put it on the back burner so to speak. A set up like that might be an
interesting coil project. ...Happy coling to all...Binny----- Original
