For the electrical connection of our electronics in the 75 kV hotbox we need an isolating transformer with min. 75 kVDC isolation to earth and a power of 80 kVA. As our system is built rather f lat, the max. height may only be 1200 mm. The fault current at max. isolating voltage may not be higher than 50 µA. All windings need to be screened.
