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
In the case of difference between two recorded energy
data, in error signal is generated and transmitted via PLC
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.
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.
DETECTION OF ILLEGAL ELECTRICITY
Methods Of Illegal Electricity Usage
1. Using the mechanical objects
2. Using a fixed magnet
3. Using the external phase before meter
4. Switching the energy cables at the meter
DEFINITION ON AMR
AMR(AUTOMATIC REMOTE READING)
automates the process of measurement
through digital communication techniques.
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.
System simulation and modeling of the detection system of
illegal electricity usage for electromechanical kilowatt-hour
AMR SYSTEM PERFORMS THE
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.
Illegal usage of electricity might be
IF , AMR & DETECTOR
SYSTEM ARE USED TOGETHER......
Can try this to minimise distribution
