Charging reactor?

I have the following problem: offline partial discharge

I want to build a DC Tesla coil and if it somehow goes through throttle the rectifier protect high frequency. As I just noticed, I'm but a so-called charging reactor, which it doubled the transformer.

Transformer: 6300Volt, 8900Volt peak, makes about 17.900Volt on the capacitor.

Because my Condi but only for 16kV DC is designed, I wanted to ask whether you can suppress the effect of charging reactors somehow without having to build out the coils behind the rectifier.

Is it enough if I hold a small spark gap? The spark that I verbaue has a breakdown voltage of 6kV about, they limited the charging voltage to this value?

An MMC with 16kV DC for a 6, 3kV is transformer (or better two parallel) ever big enough designed?

I have an energy of about 10 Joules available at 8900 volts charge voltage, is that too much? Yes just do small FS then the voltage is limited;) I invite my 15kV mmc I would bring the ZT of 30kV... set the FS on 10 mm XD
