Hi Tomas,

Yes you can connect the two 5KW transformers together providing:

1.  The secondary of each in not center tapped grounded.
2. If each transformer only has one bushing, you dont need to worry about forming a center tap between the two transformers. If two bushings are available, you will need to ground one of them. 3. You phase the primaries correctly so one transformer puts out a negative voltage when the other transformer puts out a positive voltage.

I recommend that you DON'T USE these high power transformers until you gain more experience. These power levels can be deadly. Use the 4.5KV NST for your first coil.

Yes, I have 4.5kV NST (I will check the power). And also I can have two 5kV 5kW transformers. Can I connect them in series to get 10kV?

Secondary coil is 2m x 30cm. Primary 20 windings 1.2cm copper tubing. Primary capacitor: I have a lot of high voltage capacitors so I can make any between 10 and 200 nF, according to transformer's power

So is it better to connect two 5kV in series or to use the 4.5kV NST somehow?


Thank you for advices, Tomas

    Is that correct? You have a 12kW NST already??

    I imagine 4 or 6 of your MOT's would get you pretty close to 5kW.
