3. 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.

4. 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.

6.  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.

8. 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

9. The Detection & Control System

10. 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
