Is this normal performance?
Nyx, Sun Apr 08 2007, 11:16AMIm using a 9kV line transformer and the primary to secondary turns ratio for my sg tesla coil is 10:900. I should get around 800kV if it was a normal stepup transformer, but i think im getting around 400kV (14inch sparks). Also, a fluorescent tube i placed between my secondary and primary coils (leaning on secondary coil) flickers mildly when the tesla coil is in operation. Had to off the lights to notice the flicker. Does that mean i havent got the 2 circuits to resonate yet? Thanks!

Actually, you are probably getting much much less than 400kV. With a Tesla coil, you cannot use the arc length as an indication of voltage unless you can ensure single shot. This is because, a Tesla coil is repetive pulsing device so each new arc typically travels in the previous arcs ionized channel, thereby allowing it to travel easier through the air, and hence longer arcs.
You didn't say what the output current of your 9kV transformer is, so its hard to say if your performance would be typical for that transformer.

Oh i see. My transformer is a 9kV 30mA one.

Yes, I would expect that to be a typical performance from a 9kV, 30mA powered Tesla coil. With good tuning etc..., you might realistically get about 20 inches out of that.
