INTRODUCTION

Power Line Communication (PLC) is the technique in

which the communication is takes place over the same line that deliver electricity.

In this technique, a high frequency carrier is injected onto the power line.

The data to be sent is modulated with the injected carrier.

It has a wide range of application possibilities. Automatic Meter Reading (AMR) is an important among all.

Automatic Meter Reading (AMR)

AMR a very useful application of PLC.

This provides remote recording of usage of electricity of an user.

The reading of the Meter is translated into digital form in order to send the metering data from the user to a Base station.

The Digital metering data is send to the Base station using PLC modems.

The Base station unit consists of Modems,Receivers, Data Concentrators, Controller,Host upload link, and Host Computer.

METHODS OF ILLEGAL USAGE OF ELECTRICITY

Using Mechanical Objects

Using a fixed Magnet

Using external phase before the meter

Switching the energy cable at meter connector box

The Detection & Control System

The Detection & Control System

In order to detect illegal usage of electricity, a PLC modem and an energy meter chip for every subscriber are added to an existing AMR system.

The detector PLC s and energy meters is placed at the connection point between distribution main lines and subscriber’s line.

The recorded data in kilowatt-hour meters for every subscriber are sent to host PLC modem via PLC modems, which is placed in subscriber’s locations.

On the other hand, energy meter chips reads the energy in kilowatt-hours and also send the data to host PLC unit
