Re: purpose of a variac?

Hi Bart,

I bet this is the real reason that an SRSG needs to be rephased as the power is brought up. Other theories were the leakage inductance in the variac and the nonlinarities of the NST. Dmitry will be happy :-))

An rsg is (normally) adjusted for minimal electrode spacing. It "will" fire at reduced voltages. I haven't read the documents your referring to, but I can only assume their thinking rsg (if static gap, then I would agree). Rsg's will fire at reduced voltages.

As the
voltage is turned up by the variac, the electrodes will arc sooner (before alignment).
