In order to test the residential meter-reading channel, an automatic impedance test system for low-voltage power line carrier communication network was set up and management software was developed. This system can be used for remote automatic continuous impedance testing in the condition of multi-carrier frequency, and for automatic sweep impedance testing by local USB connection, and also capable of operate stably in long term, The variation of impedance modulus and phase under the influence of heating equipment in the winter was analyzed based on long-term test results of the system, and the impedance for low-voltage power line carrier communication channel was provided for impedance matching and characteristics analysis.
