Re: Run capacitors for PFC capacitors?

Eric,

They are used on NSTs not for current limiting, but for bringing the voltage
and current phase together, to eliminate excessive amperage draw that may
blow the 15 or 20 amp breaker in the average 110 volt line these smaller
coils run off of.  They are not used for current limiting, just correction.
Sorry if I wasn't clear on this.  I would assume that you would be using
some sort of an inductive ballast to keep current draw to sane levels, and
more than likely you will be installing a dedicated line to power your
project.  I suppose that all inductive loads could benefit from PFC, but
with a dedicated line and ballasting, it will be unnecessary.  If this
inductive load were running something 24/7, then maybe you would be easing
the pain on your electric bill a little, but for short duration TC use, not
required.  Ed Wingate mentioned that the cost for running his maggie for
fifteen minutes was in the pennies, and it's a pretty large setup.  I think
a better investment would be a huge line filter for your dedicated line, as
this will help prevent feedback and outlets blasting out of the walls two
rooms away.  (Guess how I know!)

Hope this helps.
