TV cameras and DRSSTC(how do they go together)

[Miki_407]

So i got a invite to present my drsstc on live tv. Do any of you have experiance with how good are tv cameras shielded. How low should i keep the power? It is in a RTCG in Montenegro so don't expect newer cameras.

These are generic EMI reducing methods.

1) Use completely separate RF ground, copper tape/ribbon if possible
2) Avoid ground strikes, these produce the highest peak noise
3) Use a output inductor, like you can see in ArcAttack videos, to limit the current
4) Artificial ground plane / counter poise underneath coil
5) EMC filters
6) Generator for coil or at least a separate mains supply from a group not feeding the rest of the studio

Turns out my drsstc broke 2 days ago so nothing of it on TV.

What happened?

Well i had it arc back to primary. Then i removed the secundary so i can test with a sheet of metal as a load. It worked but very weak.
So i gone and checked. I found that my over current protection was set at 0 amps. Replacing IC fixed that. All other passive components worked.
Still didnt work as it did before. I dont know is this suppost to be like this but removing the sheet metal increases the power draw and placing it back drops it. So with sheet metal it is 0.2amps at 40v and without 0.4amps at 40v.
So i continued searching for a problem. Igbts worked, gdt worked, interrupter worked, ud 2.7 seems to work.
I will ask in drsstc section of this forum if i dont fix it.
