Applebeck's HV Tranformer closed loop?

[gsmsslsb]

Are you saying that the output voltage written on a NST is peak voltage not RMS.
I hope not becayse I have just made a 19 stage Cockroft walton cascade and set a neon sign transformer in rubber today and all my calcs were for 9000 volt RMS not 9000 volt peak

Unfortunately that is what I am saying but you are welcome to research it yourself.  It's just been my experience that every time I've looked into this that this seems to be the end conclusion.

Had some MOT's lying around so I tried a quick setup.
Input -- 120 volts , 10 to 15 amps depending on which MOT was used for primary imput
Output-- as claimed 257 volts,  have not checked current capability.

Mot's get hot!

i think you will find that transformers are rated in volt-amps not watts. keep an eye on the power factor.

@ Vince,  Thank you for sharing your setup picture.

May I suggest that you try inserting a Dimmer between the wall outlet and the first MOT.  Use a Dimmer that controls ceiling fans so it can handle the MOT Inductive Load.  They generally cost less than $10.  Just insert it in series with the Hot Wire from the wall.

Don't forget to put a Light Bulb(s) on the Final MOT for a Load.

Don Smith said he used a Dimmer on almost all of his O/U devices.
