Re: [TCML] cap strings

[Mddeming@xxxxxxx]

Hi Marko,
 
    The voltage seen by each cap is inversely  proportional to the 
capacitance of each unit. You can calculate the reactance of  each cap as 
Xc=1/(2pi*f*C), then calculate the drop across each as if the Xc's  were series resistors. 
If your caps are of equal capacitance, the small  ones WILL blow.
 
Hope this helps,
 
Matt D.

Hi  group,

If a string of caps in series have different voltage ratings, do  the 
ratings add, or does the voltage add evenly
across each cap?   In other words, if the string has one 20kv cap and four 
1.5kv caps with  25kv across the
string, does each cap see 5kv and the 1.5kv's blow, or does  the rating of 
the string equal 26kv and everything
is  fine?

Thanks,
Marko
