POWER SOURCE FOR TESLA COIL
BACK TO TTTC PAGE
In the front of the image you can see my mains transformer. It is a 600 VA potential transformer with a raport Np/Ns = 60/1. I use it in reverse, of course. Fed by mains at 220 VAC@50 Hz I obtain 13,200 volts, a very good voltage for a tesla coil. I am using like external ballast two water heaters imersed in water (for cooling), 1 kW each, connected in parallel between them and in serie with the primary of the PT.
