【 摘 要 】

This paper discusses the issue of dependability of a measuring system from the electromagnetic compatibility (EMC) point of view. During the tests, the equipment for conducting electromagnetic compatibility tests was used. The tests were carried out in accordance with the EMC Directive 2014/30/EU and the harmonized standard IEC 61000-4-6. The measuring system equipped with non-classical piezoelectric transducers called MFC was considered. The MFC transducer was used as a sensor connected to the NI 9191 CompactDAQ Chassis. During the research, the influence of conducted disturbances on the transmission wire was examined. One of the elements of the test bench was an EM-clamp (providing both inductive and capacitive coupling) consisting of a tube of split ferrite rings of two different grades, which can be clamped over the cable under test in a non-invasive way.
