Power Line Carrier Communication, often called PLCC, is used for speech data transmission as well as protection of Transmission Lines. Carrier current used for Power Line carrier Communication has a frequency range of 80 to 500 kHz. PLCC is mainly for telemetry and telecontrol in modern electrical Power System.
Power Line Carrier Communication is used for the Carrier Tripping and Direct Tripping in case of Distance Protection. For detail of how does Distance protection relay sends and receives carrier signal, read Distance Protection [1]philosophy.
Whenever there is a fault in the line, it is very much important to isolate the fault. Merely tripping of breaker at one end of line cannot isolate the fault. Breaker at the other end of line should also open. Let us consider a simple diagram as shown below.
