Screening attenuation as a parameter of screened cables used in converter systems is one of the indicators of screen efficiency. Catalogue data rarely considers that parameter, especially with the division on frequency bandwidths. Screening efficiency may be deduced by analysis of the cable’s construction and type, but based on this, it may only be roughly estimated. The results of screening attenuation tests in a wide frequency bandwidth for chosen cable types are presented in the article. The methods of cable parameters testing based on standard PN-EN 50289-1-6:2009: Communication cables – Specifications for test methods. Part 1–6: Electrical test methods – Electromagnetic performance, were used. Afterwards, the emission of radiated electromagnetic disturbances of the converter drive was measured. The converter was using chosen cable types, for which screening attenuation was determined. Comparisons of the obtained results were presented and the influence of the screen type and cable parameters on the emission of radiated electromagnetic disturbances was analyzed. The obtained measurement results and presented analysis in the field of electromagnetic compatibility may be useful for designers of converter drive systems.
