    Abstract: A converter station for power transmission by means of high voltage direct current has an electrode line protective device for detection of ground faults on the electrode line of the station. An alternating voltage generator injects an alternating signal with a predetermined frequency on the electrode line. The two ends of the electrode line are provided with suppression filters tuned to the measuring frequency. The suppression filter arranged at the remote end of the electrode line is matched, by means of a resistor to the wave impedance of the electrode line. An impedance measuring device senses the impedance of the electrode line at the feeding point in relation to the ground at the measuring frequency. An indicating signal is delivered from the measuring device if the impedance measured deviates from the impedance of the electrode line when in a faultless state.
