Annotation of standard text IEC 62153-4-17-ed.1.0 :

IEC 62153-4-17:2018 applies to the testing of the reduction factor of multi-element metallic cables used in analogue and digital communication and control. The described method is generally applicable to all screened metallic cables. The reduction factor describes the screening effectiveness of a cable screen at frequencies below 1 kHz with a ratio of voltages describing the screened and unscreened situation. During the measurement, the cable under test is connected to a specific current loop arrangement. LIEC 62153-4-17:2018 sapplique aux essais sur le facteur de reduction de cables metalliques a elements multiples utilises pour les communications et les commandes analogiques et numeriques. La methode decrite est generalement applicable a tous les cables metalliques ecrantes. Le facteur de reduction decrit lefficacite dun ecran de cable a des frequences inferieures a 1 kHz par un rapport de tensions decrivant la situation ecrantee et non ecrantee. Pendant la mesure, le cable en essai est raccorde a une boucle de courant specifique.
