Abstract: PURPOSE: A high voltage device is provided to reduce various VFTs(Very Fast Transient) by diversifying the arrangement and the size of transient reduction units. CONSTITUTION: A high voltage device comprises a conductive element(121) and a transient reduction unit(130). The conductive element conducts the current of the high voltage. The transient reduction unit reduces the voltage peak of a VTF by generating an arcing. The transient reduction unit includes at least one arc formation generation surface and at least one permanent electricity contact part. The permanent electricity contact part is connected to the conductive element. When a transient electric potential difference between the conductive element and the transient reduction unit is greater than a critical value, the arching is generated between the transient reduction unit and the conductive element.

Abstract: The system has a contact (3) including a tulip-shaped contact unit, which is provided on a fixation plate. The plate is connected to an axle tube, where tube and the plate are made of copper. The contact unit has contact fingers including inner and outer surfaces. The surfaces fit into a counter contact (2) when a switching device is in a closed operating condition to form contacting surfaces for supplying current to the contact (2). An independent claim is also included for switching device including an electrical contact system.
