Implementation of Power Line Communication for energy measurement

Power line communication (PLC), also known as power line carrier, is a system for transmitting information on an electrical conductor used for carrying electric power from high voltage transmission lines, distribution lines, and to lower voltage lines used inside buildings. All PLC systems operate by applying a modulated carrier signal on the existing electrical wiring system. There are different types of power line communications, depending on frequency bands used. The aim of this work is to receive the monthly energy consumption from a remote location directly to a centralized office. In this way we can reduce human efforts needed to record the meter readings which are till now recorded by visiting every home individually.This can be achieved by the use of Microcontroller unit that continuously monitors and records the Energy Meter readings in its permanent (non-volatile) memory location. This system also makes use of a PLC modem for remote monitoring and control of Energy Meter
