Patent ID: 6954345

Claim:
A generator for producing high voltages comprising: at least one generator winding; a generator circuit for connection to a network, the at least one generator winding connected to the generator circuit, the generator circuit having means for protection against overvoltages; wherein the at least one generator winding is subdivided into a number of winding sections each having winding insulation such that the insulation level of the at least one generator winding is graduated; wherein the overvoltage protection means has a number of overvoltage protection elements each associated with respective individual winding sections and whose response levels are matched to the requirements of the associated winding section; wherein the at least one generator winding comprises a plurality of generator windings connected together at a star point which is not grounded, each of the plurality of generator windings being subdivided into winding sections, each of the winding sections matched with an associated overvoltage protection element, and further comprising an overvoltage protection element connected to the star point.
