Terry Filters - Basic Education

["Tesla list" <tesla@xxxxxxxxxx>]

After putting together a Terry filter & wiring it into my TC, I 
started wondering what this thing is supposed to do.  I know, this 
might have been a better question to ask before I built it, but 
sometimes that's how I do things.  Actually I pretty much know WHAT 
it's supposed to do, but I haven't been able to find good basic level 
info on HOW it does what it does - i.e., what each component does.  I 
mean basic layman level sort of like Terry filters for dummies.  I 
understand the safety gap part pretty well.  But not the other 
components.  For example I know how a capacitor works, but I'm not 
clear on how it protects the NST.

Any way, I'd appreciate any info on this that any of you would like 
to share.  Thx, Dennis Hopkinton MA
