A generator for producing high voltages and having at least one generator winding () is connected via a generator circuit () to a network (), which generator circuit has means () for protection against overvoltages. Improved protection against higher voltages is achieved in that the at least one generator winding () is subdivided into a number of winding sections () 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 (), which are associated with the respective individual winding sections () and whose response levels are matched to the requirements of the associated winding section.
