Hi Max,

I get:

System Type		Cap Size	Primary Current

Resonant		42.44nF		26Arms
LTR static gap		60nF		29Arms
LTR rotary gap		112nF		55Arms

The voltage per string should add up to 21000 volts.  Typically, MMC caps
take 3 amps RMS per string so you should have enough strings such that the
total current matches the above current numbers.  Basically just taking the
numbers for a single 15/60 system and multiplying by four.

Your 0.0043uF caps seem rather low for an MMC.  Perhaps you meant 0.043uF?

21000 / 1500 = 14 caps per string.  Each string has a value of 0.0043 / 14
= 0.307nF.  To get to 42.44nF you would need 138 strings!  If you meant
0.043uF then you would need 14 strings.

Cheers,

	Terry
