| Abstract: | Analysis was made to coupling means and coupling path of electromagnetic interference signal from communication cables. According to characteristics of the communication cables, anti-interference measures of the communication cables were researched. To reduce the external electromagnetic interference, the main techniques for the communication cables like shielding, grounding and filtering were adopted. Meanwhile the electromagnetic interference from high-voltage overhead lines was discussed too. |
