This document summarizes a seminar presentation on a microcontroller-based power theft identification system. It introduces power theft as the illegal use of electrical power without paying the supplier. It then describes two common ways that power theft occurs: slowing down electricity meters with magnets, and inverting meters to make them count backwards. The proposed system architecture integrates a wireless network with the electrical grid to monitor multiple points using data aggregation algorithms. A microcontroller like a PLC would be programmed to detect theft and control the electrical distribution in response.

3. INTRODUCTION
(POWER THEFT)
>it is the use of electrical power without a contract
with a supplier with total or partial bypassing of the
metering system or interfering with this system in
such a way so as to adulterate its measurements,
>contract is understood here as a valid
oblingation to deliver power and
to pay for it.

4. HOW IT OCCURS ?????
1-(SLOWING DOWN THE METER)
>A common method of tempering older meters is to attach
magnets to the outside of the meter.
>when this happens, the rotor disc is exposed to a high
magnetic field. Hence the resultant is
opposing magnetic field to the rotor
highly increased leading
to slowing down of rotor or perfect
stopping of the disc rotation.
>The electricity meter is thus
manipulated and ultimately power
is consumed without being paid.

5. 2-(INVERTING THE METER/FEEDER)
 Another common form of electricity theft is
to invert the meter (pull the meter out of the
socket & plug the meter back in upside
down, which causes the meter to run
backwards & the kWh register to count
down instead of up).

8. MICRO-CONTROLLER BASED
POWER THEFT MONITORING
 OVERVIEW-
 The whole system architecture is based on
integrating wireless network with existing electrical
grid.
 The proposed module also incorporates different
data aggregation algorithms & effective solutions
needed for the different pathways of the electricity
distribution system.

15. PLC (PROGRAMMABLE LOGIC CONTROLLER)
 It is a digital computer used for automation of
elecctromechanical process.
 The PLC’s are designed for multiple input and
multiple output.
 Program to control machine operation are typically
stored in non-volatile memory.
 It is an example of a hard real time system since
output results must be produced in response to
input conditions within bounded time.

16. PROGRAMMING OF PLC
 Early PLC’s were programmed by using specific
purpose programming terminals.
 The programs were stored in cassette tape cartridges.
 Facilities of printing and documentation were very
minimal due to lack of memory.
 The very old PLC used is non-volatile magnetic core
memory.
 Modern PLC’s used are EEPROM or EPROM as a
memory.
