What is power line carrier communication?
When transmitting data by means of power line communication, the transmitter modulates the data to a high frequency carrier, and then is coupled to the power line through the coupling circuit after power amplification. The peak peak voltage of the signal band is generally no more than 10V, so it will not cause any adverse effects on the power lines.
Power line communication technology (Power Line Communication) appeared in the early 1920s. It is a means of data transmission and information exchange using the existing low-voltage distribution network as the transmission medium.
Power line carrier communication (power line communication) to power transmission line as carrier signal transmission medium power system communication. The transmission line has a support structure is very strong, and set up more than 3 conductors (usually a three-phase conductor and one or two overhead transmission line), so the current at the same time, with the transmission of the carrier signal, economical and reliable. This comprehensive utilization has long been the preferred means of communication for all electric power departments in the world.
