Content preview: HI Dex, That's a 100 kV transformer as used in HV labs, right? I know them well. They can be stacked to 300 kV and have a low voltage output on the HV side which is connected to the primary winding (which is a 100 kV above GND) of the next transformer. Does it still work at 30 kHz?
