Measurement and Research on Attenuation Characteristics of Low Voltage Power Line Communication Channel

Signal transmission attenuation characteristics of low voltage power distribution network is an important factor must be considered by the power line communication system design. The effects of power line network on the power line communication channel attenuation are studied, including cable cross-sectional area, length and T network structure. With the experimental and simulation results, the relationship between low voltage power line cable length, the network structure and the power line communication channel attenuation is analyzed.
