Re: Static Gap Break Rates



Original poster: "Christoph Bohr" <cb@xxxxxxxxxxxxxxx>

Hello Curt.

The line frequency does not limit the
breakrate. With higher current you
simply charge the cap severall times
during each half cycle and reach full
charging voltage to trigger the gap.
This is why the breakrate increases as
you ramp up the variac.

Christoph Bohr
