Re: Cap size for pig?

Well, first, we didn't include MOTS, PTs, or pole mount transformers (PDT) 
because those are highly variable, whereas NSTs are pretty well 
defined.  We also rather felt that people constructing TCs from PTs or PDTs 
ought to know enough about TC design to get in the ballpark as far as MMC 
design goes.  In fact, we (I) get more MOT MMC questions than PT or PDT MMC 
questions, and have only been asked once or twice for advise on an MMC for 
a PDT (and IIR was more of a "I was thinking....  does this sound 
good?").  The "preferred" cap size for a PDT is completely dependent upon 
the PDT's voltage and the ballast settings, the latter of which is 
virtually infinitely variable.

Using a triggered spark gap, either triggered or SRSG, allows for very 
precise timing of the gap firing, which is necessary to prevent a static 
spark gap from premature breakdown.  I don't fully understand why it all 
works, but it does.  Hopefully someone else can answer the LTR sizes 
question more fully.
