T/CCSA 433-2023 Electromagnetic compatibility requirements and testing methods for power line communication equipment
Basic Information
Scope
Scope: This standard applies to devices that operate at a working voltage of less than 600V and a working frequency between 1.75MHz and 87.5MHz, and communicate via AC (phase-to-phase, phase-to-neutral) or DC power lines. The devices covered by this standard include, but are not limited to: — Home broadband access equipment, such as power line modems; — Internet of Things communication devices, such as sensing layer devices that communicate via power lines; — Devices that use power lines to transmit monitoring signals between communication base stations. For communication devices with power line communication ports (integrated power line modem function) other than home power line communication devices, the test methods provided in this standard are applicable to evaluating the electromagnetic compatibility of the power line communication ports. The electromagnetic compatibility evaluation of other ports of the product shall refer to the corresponding product standards, and in case of conflict between the anti-interference test requirements in this standard and those in the product standards, the requirements in the product standards shall prevail. For the application of power line communication devices in specific industries (such as aviation, transportation, fisheries, and marine), the requirements in this standard are for reference only. When there are inconsistencies between the requirements in this standard and those in the relevant standards for industry applications, the relevant standards for industry applications shall prevail. Main technical content: This standard specifies the electromagnetic compatibility technical requirements and test methods for power line communication devices, including disturbance limits, anti-interference levels, test methods, and performance criteria.
