For our measurements we need a high voltage transformer with a voltage of 3000 V 50 Hz. The transformer has to be free of partial discharge. The max. PD at 3 kV that is allowed has to be less than 5 pC.
We build a high voltage transformer, which is constructed for very low fields. The vacuum potting at 10 mBar remaining pressure makes sure, that all airgaps are filled with the highly fluid cast resin.
Power: 50 VA Primary: 2 x 50 V Secondary: 3000 V Current: 0,016 A Free of partial discharge
