A device for sensing electric discharges in a test object that includes at least two electric connecting conductors. The device comprises a transducer equipment and evaluating equipment. The transducer equipment includes at least one transducer for direction-sensitive sensing of current pulses through the connecting conductor by means of sensing a magnetic field that is generated by the current pulse. The transducer delivers a transducer signal to the evaluation equipment in dependence on the current pulses and their direction. The evaluation equipment generates an indicating signal that is independence on received transducer signals to indicate the signal that indicates an electric discharge in the test object.
