DRSSTC 1 Problem capacitor C6

[andreaf90]

Hi Mads Barnkob
I’ve a problem with my DRSSTC, yesterday i’ve built the primary coil and after that i’ve tested all.
When i turn on DRSSTC the differential (30mA) of my house brake-out.
After various tests i’ve seen that the problem is capacitor C6 that i’ve connected from negative rail to ground of my house together strike rail, RF, ecc. (i’ve used one 0.15uF 2000VDC 942C20P15K-F). If i disconnect C6 all work fine and when DRSSTC turn on i listen a beep beeep from MMC and primary coil. So i think it works ok…true?
Do you think I was wrong to use that type of capacitor?
What capacitor can i use?
In your video I see that by connecting it to the ground works, I can not understand.
Thank you

Hi AndreaF90, welcome to the forum

You could try to use a smaller value capacitance, if the leakage current is too high in the capacitor, you actually do have earth fault conditions and your breaker should trip.

Generally it is the scheme by Steve Ward that most people uses: http://stevehv.4hv.org/DR_plexi/general%20wiring%20scheme.pdf

Some of the advices on that and other methods are in this thread: http://4hv.org/e107_plugins/forum/forum_viewtopic.php?163880
