WebJan 1, 2015 · The data is carried by either fibre optic or telephone lines to avoid HV transmission power lines . As illustrated in Fig. 1 , the data is injected into the MV power distribution grid and special electronic devices, known as repeaters, re-amplify and re-transmit the signal because the signal loses strength as it travels along the MV power line. Power-line carrier communication (PLCC) is mainly used for telecommunication, tele-protection and tele-monitoring between electrical substations through power lines at high voltages, such as 110 kV, 220 kV, 400 kV. [2] The modulation generally used in these system is amplitude modulation. See more Power-line communication (also known as power-line carrier or PLC) carries data on a conductor that is also used simultaneously for AC electric power transmission or electric power distribution to consumers.
