Methods Of Illegal Electricity Usage
1. Using the mechanical objects
2. Using a fixed magnet
3. Using the external phase before meterterminals
4. Switching the energy cables at the meter
connector box

PLC Presents an interesting and economicalsolution for automatic meter reading (AMR).
If an AMR system via PLC is set in a powerdelivery system, a detection system for illegalelectricity usage may be easily added in theexisting PLC network.
In the detection system, the second digitallyenergy meter chip is used and the value ofenergy is stored. The recorded energy iscompared with the value at the main kilowatt-
hour meter. In the case of difference between two recorded
energy data, in error signal is generated andtransmitted 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 inthe energy supply sector.

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

AMR(AUTOMATIC REMOTE READING)
automates the process of measurement of
electricity used through digital
communication techniques. Bring intelligence into the revenue cycle
and manage it.
The revenue cycle includes metering, billing
operating, customer and the services.

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 thedistribution transformer and the
configuration of the addressing format of PLC
signaling must be designed carefully.

Most economically viable technology fortransferring Meter data to DCU.
Uses the technique of communicating thedata 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 foranyone to access, such that its control is
easy. It is very economical and is reliable solution
when it is compared with the economical losscaused by illegal usage.

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