This document proposes a solution to remotely detect illegal electricity usage through power line communication (PLC). It involves installing a secondary digital energy meter chip to record energy usage, which is then compared to the main meter. If a difference is detected, an error signal is generated and transmitted over the existing PLC network. This provides an economical way to add illegal usage detection to an existing automatic meter reading system using PLC.

3. ABSTRACT
 PLC Presents an interesting and economical solution for
automatic meter reading (AMR).
 If an AMR system via PLC is set in a power delivery system, a
detection system for illegal electricity usage may be easily added
in the existing PLC network.
 In the detection system, the second digitally energy meter chip
is used and the value of energy is stored. The recorded energy is
compared with the value at the main kilowatt-hour meter.
 In the case of difference between two recorded energy data, in
error signal is generated and transmitted via PLC network.

4. INTRODUCTION

The automatic meter reading(AMR)
system as become a necessity for most suppliers as
deregulation, free customer choice and open market
competition occur in the energy supply sector.

6. PLC installation

7. INSTALLTION OF PLC
Power meters with PLC modules near the top of the
power polls. Previously, it was enough to install
power meters in high places, not in low places such as
the house wall, to prevent users from using power
illegally by connecting cables, or by using tampered
meters.

8. DETECTION OF ILLEGAL ELECTRICITY USAGE
Methods Of Illegal Electricity Usage
1. Using the mechanical objects
2. Using a fixed magnet
3. Using the external phase before meter terminals
4. Switching the energy cables at the meter
connector box

9. DEFINITION ON AMR
AMR(AUTOMATIC REMOTE READING)
automates the process of measurement through
digital communication techniques.

10. DETECTION AND CONTROL SYSTEM

11. ADVANTAGE OF THIS SYSTEM
Most economically viable technology for transferring
Meter data to DCU.
Uses the technique of communicating the data over
existing Electrical Lines which carry LT power to the site.
Since the connection point is usually in the air or at
underground, it is not suitable for anyone to access, such
that its control is easy.
It is very economical and is reliable solution when it is
compared with the economical loss caused by illegal
usage.

13. System simulation and modeling of the detection system of illegal
electricity usage for electromechanical kilowatt-hour meters

14. AMR SYSTEM PERFORMS THE FOLLOWING
FUNCTONS
Every user has two PLC modems; one is for AMR and
the other is used to send the data from second
energy meter chip to host PLC modem.
An energy meter must be connected in the
connection box between a home line and main power
lines.
The host PLC unit must be placed in the distribution
transformer and the configuration of the addressing
format of PLC signaling must be designed carefully.

15. CONCLUSION
illegal usage of electricity may detected
Once this proposed system is tried in real power
lines, the distribution losses can be reduced
effectively.
