A generator for producing high voltages and having at least one generator winding ( 12 ) is connected via a generator circuit ( 10 ) to a network ( 19 ), which generator circuit has means ( 15, . . . , 17 ) for protection against overvoltages. Improved protection against higher voltages is achieved in that the at least one generator winding ( 12 ) is subdivided into a number of winding sections ( 12 a-c) whose winding insulation is designed such that the insulation level is graduated, and in that the overvoltage protection means have a number of overvoltage protection elements ( 15, . . . , 17 ), which are associated with the respective individual winding sections ( 12 a-c) and whose response levels are matched to the requirements of the associated winding section.
