MOT Tesla coil

Postby pierrepaul » Fri Apr 08, 2016 7:23 am

Hello

this is my project rotary spark gap tesla coil

-220v 25A, 5Kva.
-estimated discharge: 7 foot
the challenge is to achieve a robust tesla coil with little money, (recovery, "barter")

In France, it's difficult to have the big equipment because of the price (especially capacitors), although EUROFARAD is a French company.

The eclator is under construction it will be a copy of terry ARSG
The power supply is a 9kva VERILEC
The control box can support up to 10kw of continuous power
