PCT No. PCT/SE96/01126 Sec. 371 Date May 12, 1997 Sec. 102(e) Date May 12, 1997 PCT Filed Sep. 10, 1996 PCT Pub. No. WO97/10515 PCT Pub. Date Mar. 20, 1997A device for sensing electric discharges in a test object with at least two electric connection conductors comprises transducer equipment and evaluation equipment. The transducer equipment comprises at least one transducer for direction-sensitive sensing of current pulses through the connection conductors by sensing a magnetic field, generated by the current pulses, and the polarity thereof. The transducer delivers a transducer signal to the evaluation equipment in dependence on said current pulses and their direction. The evaluation equipment generates, in dependence on received transducer signals, an indicated signal indicating an electric discharge in the test object. |
