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.
