    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.

SOLUTION: The electrical conductor includes a conductor piece 30, and the conductor piece extends along an axis A and has a cylindrical envelope surface and two electrical connections 10 and 20. One 10 of the two electrical connections has two contact surfaces 11 and 11' which are aligned parallel to one another. This is achieved, in part, because the other 20 of the two electrical connections is connected without a joint to the conductor piece 30, and the electrical connection 10 is hollow and, at right angles to the axis A, has an oval profile with two longitudinal faces which form the two contact surfaces.
