Dielectric and resistive properties of solid insulating materials – volume resistance

IEC 62631-3-1 specifies the general method for measuring the volume resistance and volume resistivity of solid electrical insulating materials using DC voltage methods. The test determines how well a material resists the flow of direct current through its bulk.The test uses a three-electrode system (guarded electrode configuration) where a DC voltage is applied across a […] Read more

Test method for measuring of the screnning attenuation

IEC 62153-4-4 specifies the test method for measuring the screening attenuation (shielding effectiveness) of cable screens used in metallic communication cables.The test typically uses a tube-in-tube measurement method where the shielded cable is placed inside a test fixture and the ratio of electromagnetic energy transmitted through the shield versus the incident energy is measured across […] Read more

Electromagnetic compatibility (EMC) – Surface transfer impedance – Triaxial method

IEC 62153-4-3 specifies the triaxial test method for measuring the surface transfer impedance of cable screens and connectors. Surface transfer impedance quantifies how much electromagnetic energy couples through a cable shield from external fields to the internal conductors.The test uses a triaxial test fixture consisting of the cable under test placed inside a precisely dimensioned […] Read more
