RE: [TCML] DC rating for 7KV5 transformer

["Scott Moseley" <scott@xxxxxxxxxx>]

Thanks for your quick reply.  The caps were;

ASC SHV24
0.010MFD +/- 10%
10Kv WVDC

As I said, "were".  They're now crispy, and make a cool light bulb when hooked up to power.  For the few mins the coil was running, it sounded ANGRY.  But I STILL can't get streamers from the top load.

You need to look at the RMS current rating for the capacitor, not just the voltage rating. 
As well as the peak current rating, is the cap rated for pulse duty? 

Also pay attention to the type of dielectric inside the capacitor, polypropylene is the best. 


for a static gap i would guess a 0.01uf cap, and for a SRSG perhaps .02. 
I usually shoot for tipple the RMS voltage as the cap voltage. 

What caps were you using out of curiosity ? 



Thanks,

Just wondering what rating I should use for caps if my NST is 7.5KV @ 30mA. 
I tried 2 10Kv caps in series, and they burst into flames (and so did the 
$20 I spent on them). Ideas?
