The Influence of Cables in The Interference Suppression Characteristics

In order to study the changes of field-line coupling attenuation, in the laboratory environment, the transmission mode of the cable, the location of the cable grounding point, the grounding method and the high-frequency capacitor absorption loop at the connection end of the cable and the equipment and the different combinations of these measures The comparison of the following test results determines the method to effectively suppress the field-line coupling, quantifies the anti-interference ability, provides effective and easy anti-interference measures for engineering applications, and can provide help for the electromagnetic compatibility design of the system.
