摘要：
In this paper a novel approach to measure currents noninvasively in a multi-conductor cable with conductor level resolution is presented. The measurement is based on an evaluation of the magnetic field outside the cable. A sensor-device based on this approach can be installed without removing any part of the isolation, separating the conductors inside the cable or even turning of connected electrical consumers. It is therefore considered noninvasive. Based on this approach a sensor-device is developed and tested. A maximum measurement deviation of 4 percent is achieved.
