Customer’s demand

We are in need of a power supply with 3 kVA power, which lies 50 kVDC over earth potential. Our sensitive measurement devices may not be interfered by stray fields of the transformer. Main disturbances should be filtered and the separating transformer has to be safeguarded by the rated current. For the installation a 19” aluminum housing should be used.

Solution

We buidl a high potential separating transformer with a low strayfield toroidal construction. Additionally the transformer is mounted in a screening housing, made of mu-metal, and as last it is placed in a 19” housing. To be able to safeguard with the rated current, a current inrush avoider is set in front of the primary winding. The high voltage output is feasible by a HV-transit and with
HV-laces.
