1. A method of determining the resistance of a winding insulation, comprising:

  • applying a pulsed voltage having a maximum value and a minimum value to the winding insulation;

    determining the maximum current flowing through the winding insulation;

    determining the minimum current flowing through the winding insulation;

    determining the difference between the maximum and minimum current; and

    calculating the winding insulation resistance based on the difference between the maximum and minimum current.
