Toroidal isolating transformer 10 kVDC for forwards and backwards operation. We are a supplier for devices to analyse and monitor HV cables. The quality of the cables should be evaluated with a dielectric measurement. For this we need a potentialfree mains voltage of 230 V which lies 10 kV above ground potential. Forwards and backwards operation must be possible. Thus the voltage factor should be rather small. The transformers rated power is only at 20 VA.
