Abstract
A method is provided for computing an insulation resistance (R) in an ungrounded DC power supply system () at a changeable DC line voltage (U, U). In two consecutive measurements at the point in time of the respective settled state of a first and second pulse amplitude (U, U) of a measuring voltage (U) superposed on the DC power supply system (), the insulation resistance (R) is computed at a changed DC line voltage (U, U). In this context, a correction factor K is derived from a measured first and second total measuring current (I, I) and from the respective current first and second DC line voltage (U, U) in order to determine the measuring pulse current (I, I) required for computing the insulation resistance (R).
