  "textContent": "A method compensates for leakage currents in a protective conductor of an electrical power converter. The method includes: using a first differential current sensor for determining a differential current depending on a phase conductor current in a phase conductor and a neutral conductor current in a neutral conductor; feeding a compensation current into the phase conductor and/or into the neutral conductor via a first compensation circuit; using a second differential current sensor for capturing a signal representing remaining residual leakage current; converting the signal representing the residual leakage current to a frequency domain; generating a compensation signal for the residual leakage current in a frequency-selective manner; converting the compensation signal to a time domain; supplying the converted compensation signal converted to the first compensation circuit or a second compensation circuit; and feeding a residual compensation current corresponding to the compensation signal into the phase conductor(s) and/or into the neutral conductor.",
