power line carrier
Power line carrier (PLC) describes the entire process of communication usinghigh-voltage powerlines as the means for transmission. Powerlines provide a reliable link because of their unusually rugged construction,and also offer freedom from restrictions imposed by common-carrier regulations.

What is power line carrier communication used for?
For large power system power line carrier communication is used for data transmission as well as protection of transmission lines. Carrier current has a frequency range of 30 to 200 kHz in USA and 80 to 500 kHz in UK.
What is Lineline protection?
Line protection is often the most important and critical application for the power line carrier system. RFL鈥檚 PLC solutions are well into their fourth-generation, providing highly-reliable power system protection.
Are people leaving the power-line carrier industry?
Miriam P. Sanders Roger E. Ray Introduction While the application of Power-Line Carrier is not new to the power utility industry, the people who have historically worked on this type of equipment are leaving the industry, thereby creating a tremendous void in the expertise available.
What factors affect the reliability of a power line carrier channel?
Many factors will affect the reliability of a power line carrier (PLC) channel. The goal is to get a signal level to the remote terminal that is above the sensitivity of the receiver, and with a signal-to-noise ratio (SNR) well above the minimum, so that the receiver can make a correct decision based on the information transmitted.
