How to reduce EMC risks in power line carrier PLC field wiring?

To reduce EMC hazards in PLC field cabling, it is essential to adhere to specifications and strengthen protective measures. Cabling should be kept away from interference sources (such as frequency converters and high-power motors), with spacing greater than 1 meter. Shielded cables should be used, and the shielding layer should be properly grounded. Cables should be laid in metal cable trays and grounded. Waterproof and dustproof connectors should be used at joints to ensure shielding continuity. The field grounding system should be standardized, with a grounding resistance of less than 4Ω. Field testing should be conducted using an EMC tester to detect cabling radiation and optimize cabling routing. Reducing these hazards can ensure the system passes EMC testing on the first attempt after installation, lowering rectification costs.
