Wattmeter clamp for multicore cable: A breakthrough in electrical diagnostics

We present herein a compact wattmeter clamp for measuring electric field and magnetic field in monoconductor and multiconductor cables. The clamp allows the diagnostic of low voltage and low frequency equipments. This device performs the electric and magnetic field measurement surrounding a multiconductor power cable and permits to deduce amplitude, phase and position of each conductor in the cable. Performances of this system and experimental results have been investigated and experimentally characterized in real industrial environment.
