Summary
Power line carrier (PLC) in communications describes the procedural stages involved for the transmission and receiving of data and information using high-voltage power lines as the channel or transmission path [1] [2]. 3. Working Principle of the Power Line Carrier System A power line carrier (PLC) system is operated by the superimposition of a high-frequency communication signal in the range of 1.6 Mega-Hertz to 30 Mega-Hertz upon the low- frequency power signals[16] [17] The useful information is retrieved from the filtering process, and the power signals are prevented from entering the communication systems to damage them. The coupling capacitor is connected to the PLC system, so it filters out the low-frequency power signals and allows the high frequency communication signals to pass through the capacitor reactance of the capacitor is given in equation 1. A typical power line carrier communication system includes the following elements, which are the transmission line, Line trap, coupling capacitor tuning unit and blocking element, and relay system, Transmitter and Receiver, Protection, and earthing Battery Some of these elements are highlighted below
