Based on the characteristics of low-voltage power line carrier communication, the carrier communication performance testing method is deeply studied. With reference to the technical specifications and testing specifications of SGCC information acquisition system, a test equipment for low-voltage power line carrier communication performance testing is developed. Aiming at the problems of the sensitivity measurement, anti-noise performance and anti-attenuation performance testing in this device testing application, some ideas and methods of improvement in the laboratory environment are put forward. In order to build a more complete test system, to provide good support for the evaluation, selection and improvement of power line communication products.
