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.

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.

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.
INSTALLTION OF PLC

Methods Of Illegal Electricity Usage
1. Using the mechanical objects2. Using a fixed magnet3. Using the external phase before
meter terminals4. Switching the energy cables at
the meter connector box
DETECTION OF ILLEGAL ELECTRICITY USAGE

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

DETECTION AND CONTROL SYSTEM
![Page 11: Power Theft Detection](https://reader036.vdocuments.mx/reader036/viewer/2022082309/557d9e30d8b42a16698b5027/html5/thumbnails/11.jpg)
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.
ADVANTAGE OF THIS SYSTEM

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

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.
AMR SYSTEM PERFORMS THE FOLLOWING FUNCTONS

Illegal usage of electricity might be detected ,
IF , AMR & DETECTOR SYSTEM ARE USED TOGETHER......
Can try this to minimise distribution losses...
