Power line carrier communication using 1MHz ~ 30MHz as carrier signal can improve the bandwidth of data transmission. Using the high frequency signal as a carrier signal, with the increase of signal frequency, the attenuation range of low voltage power line channel is also increased. On the basis of the structure of low voltage power grid, the transmission attenuation model of high frequency signal in low voltage power line channel is established by using transmission line theory. The attenuation in different locations and loads is measured by experiments. Analytical results show that the attenuation of the signal increases with frequency in the 1~30MHz band. The attenuation of the signal is time varying to a certain extent. The attenuation of the signal is also impacted by the load. As the load increases, the attenuation of the signal increases.
