Re: [TCML] Overdriving NSTs

Exactly right. The gap is clamping the voltage. BPS however is increasing as is power throughput. The gap may be getting a wee bit hotter than it otherwise would, so the clamping voltage may actually be slightly lower. NST heat would be the killer if anything, so that is what I would keep an eyeball open for.

Take care,

I didn't just luck out this time.  I've done it several times already.  Of
course, that was with it running as a Jacobs ladder.  It's my understanding
that NSTs run at a lower voltage when short circuited.  In TC duty they see
higher voltage as they charge the capacitor, but since I have my spark gap
conservatively set the firing voltage has not changed at all.

Hey Phillip...

200%??  you put 240Vac into it?  ouch  you lucked out this time...probably
wont be so lucky the next time around...good chance you stressed the
insulation on the secondaries of the NST ...
