Abstract: The invention relates to a method for personal protection during high-voltage testing on a test object, the method comprising the steps of outputting a high-voltage alternating current for the test object by means of a high-voltage generation device, which has a high-voltage transformer for generating the high-voltage alternating current. The method further has the steps of determining a curve over time of at least one electrical variable at the high-voltage transformer during the output of the high-voltage alternating current, and ending the output of the high-voltage alternating current on the basis of the curve over time of the at least one electrical variable.

Abstract: The invention relates to a high-voltage transformer which is configured as a toroidal transformer. The high-voltage transformer has a magnetizable core (310) and a high-voltage winding (330) and a low-voltage winding (320) around the magnetizable core (310). The high-voltage winding (330) is embodied at least partially as a pilgrim step winding.
