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

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 subscribers line.
• The recorded data in kilowatt-hour meters for
  every subscriber are sent to host PLC modem via
  PLC modems, which is placed in subscribers
  locations.
• On the other hand, energy meter chips reads the
  energy in kilowatt-hours and also send the data
  to host PLC unit
