Re: [TCML] PFC Question (again)



Hi John,

I agree. I see PIG's as mostly STR on average and PT''s somewhere in the middle. They could all do well to run LTR, but I simply doubt that is the norm.

As far as this subject line, I don't know if PFC will help. Too many variables.

Take care,
Bart

It's possible that a few like Kevin "might" be running LTR, but I think for the majority of pig or PT users (the garage coiler), the cap size is either resonant or STR from a standpoint of cost and energy.


Bart,
For pig coils, STR is probably more common. This may be true for
PT coils too.  However many PT's are rated at 1.5kVA.  The  resonant
or slightly LTR value cap is not that large for such a coil.  The  1.5kVA
rating of a PT is very similar to many NST powered coils.  Such  coils
do well with a 120 bps sync rotary.  The cap value for a 1.5kVA  PT
is similar to the cap value used by many NST coilers.   Although
many PT coilers *may* run STR, they could run slightly LTR if they
wanted to.  In fact the cap could even be a little smaller for the  PT,
because it's not so important to keep the voltage low when using a PT, as it is when using an NST (due to PT robustness). Cheers,
John
