Power Theft Identification and Monitoring using GSM moduleAshishPanchdhar1
developed the system were we are using Arduino Atmega328 and current sensors and GSM module attached to every pole. The current sensor keeps the track of amount of current pass through it. When this supply reaches to other end of the pole than the current sensor available at pole 2 will measure the current receive and gives the reading to the Arduino Atmega328. Then the Arduino compares the current readings to the previous readings and if the supply is not approximately equal than the Atmega328 trigger the GSM module. Then the GSM module will send the SMS to the distributor that the amount of current received is not approximately equal and there is some illegal action occurred in the section from pole 1 to pole 2. This will help the distributor to overcome the losses and where the losses will be take place and the theft of the electricity

Intelligent Electric Power Management Using Zigbee with Advanced Metering Inf...Akbar Badusha
This project mainly focuses on reduction of power cut and power theft. The main reason for the power cut is shortage of power in the generation unit. We can rectify this problem through our project.
Whenever the generation falls behind a particular limit (it is set initially by EB) the power management system will automatically switched on. Power will be supplied to only the basic necessary equipment (as stated in the priority list) power to other load will be stopped so that huge amount of power can be saved without power cut.
In our project, this is achieved using NS2 software and using ZIGBEE. Whenever generation falls below the particular value, then the load will be automatically switched off based on priority. And it can also be done through an interrupt. Through ZIGBEE command the interrupt will be sent to microcontroller to cut the power to the particular load.
When microcontroller receiving the command, the relay will cut the power to the equipment. So the power will be saved.
In this project,the method to detect and to control the power theft is also stated. Other methods of power theft like damaging, by passing electrical power meter can also be detected and can be punished.
Man power can also be reduced. The power usage of the customer will be automatically updated in the EB station so there is no need of man power to take meter reading in the user side. After every two months the reading will be automatically resetted.
Is a seminar based on the concept of replacing the existing electricity metering system using in developing countries by a low cost energy meter working without human intervention. Its main components are discussed later...

3. INTRODUCTION-
POWER THEFT :DEFINITION
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
obligation to deliver power and to pay for it.
4. HOW IT OCCURS?
1.SLOWING DOWN THE
METER:
A common method of tampering
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 opposing
magnetic field to the rotor is 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 for. ex-
neodymium magnets.
5. 2.INVERTING THE METER/FEEDER:
Another common form of electricity theft is
to invert the meter (pull the meter out of the
socket and plug the meter back in upside
down, which causes the meter to run
backwards and the kWh register to count
down instead of up).
6. 3.BYPASSING THE FEEDER/METER:
Usually, the bypass supplies
power to large and stable loads
which will not trip fuses in the
case of overloads. Ex-jumper
cables.
The rest of the circuits are
supplied normally through the
meter, so the bill, which is close
to average, does not suggest a
theft.
7. DIFFERENT WAYS OF MONITORING POWER
THEFT:

Microcontroller based power theft

Power theft monitoring using
PLC.
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 and
effective solutions needed for the different
pathways of the electricity distribution system.
9. THE PROPOSED ARCHITECTURE:
The Architecture Consists Of Four Modules
Namely:
Controlling Station (CS)
Wireless Transformer Sensor Node (WTSN)
Transmission Line Sensor Node (TLSN)
Wireless Consumer Sensor Node (WCSN)
11. WCSN is a module which acts as a consumer
power metering device that measures the power
consumed by the consumer and send the data
periodically to the WTSN.
Each feeder of the transformer has a WTSN
which monitors power through each line and
collects data from WCSN ,aggregates it and sends
to the CS.
TLSN is another module associated with
distribution line, mounted in each distribution line
posts .
12. DIFFERENT PARTS AND THEIR
FUNCTIONS:
ZIGBEE:
We are using XBee-PRO OEM RF
Module whish uses the zigbee
technology.
Itis engineered to support the unique
needs of low-cost, low-power and low
data rate wireless sensor network
providing reliable delivery of data
between devices.
ZIGBEE MODULE
The XBee-PRO OEM RF Modules
interface to a host device through a
logic-level asynchronous serial port.
13. CURRENT TRANSFORMER CIRCUITRY:
We are using Allegro ACS709
current sensor IC chip.
The ACS709 consists of a Hall
sensor integrated circuit (IC) with a
copper conduction path located near
the surface of the silicon die.
Applied current flows through the
copper conduction path, and the
analog output voltage from the Hall
sensor IC linearly tracks the magnetic
field generated by the applied current.
14. MICROCONTROLLER:
The LPC2148 microcontroller is based on a16-bit/32-bit
ARM7TDMI-S CPU with embedded high-speed flash memory
ranging from 32 kB to 512 kB.
A 128-bitwide memory interface architecture enable 32-bit
code execution at the maximum clock rate.
Due to their tiny size and low power consumption, LPC2148
is ideal for applications where miniaturization is a key
requirement.
Serial communication interfaces ranging from multiple
UARTs, on-chip SRAM of 8 kB up to 40 kB, make these
devices very well suited for communication gateways.
15. LCD:
LCD stands for Liquid Crystal Display.
As the output of the circuit should be
displayed in some form or the other, LCD
display is selected as it can display 16
characters at a time.
It is also easy to interface with the
microcontroller without any decoder. So it
is better than the seven segment display.
16.
17. WORKING OF WIRELESS
SENSOR NETWORK:
The sensor network monitors the electrical grid for a specified
period of time, which may be daily, monthly or yearly.
Thus the WTSN stores the maximum demand for each consumer
including the losses.
The measured data from each WCSN is send to the neighbouring
TLSN.
The aggregated data is then sent to the next nearby WTSN. Thus
the data transfers from WCSN to the corresponding WTSN through
TLSN.
The collected data is compared with the measured data by the
energy meter.
•Normally these two data are almost same.
If there is any difference (dmc) in the collected data and the
measured data, there may be a line fault or a power theft in that
segment.
Large value of dmc indicates a line fault and small value of dmc
indicate a power theft .
18. ADVANTAGES:
The proposed system provides the solution for some
of the main problems faced by the existing Indian
grid system, such as wastage of energy, power theft,
manual billing system, and transmission line fault.
This method will reduce the energy wastage and
save a lot of energy for future use.
We can detect the location from where the power is
being stolen which was not possible before.
Optimized use of energy.
19. LIMITATIONS:
One major disadvantage of this project is that it is
not capable of detecting the exact location from
where the power is being stolen giving only a
approximation to that place.
Cannot determine who is stealing, but even no
other existing system is capable of doing this.
If implemented on a large scale it may take a lot of
time and manual input.
20. CONCLUSION:
This method reduces the heavy power and revenue losses
that occur due to power theft by the customers.
By this design it can be concluded that power theft can be
effectively curbed by detecting where the power theft occurs
and informing the authorities.
Also an automatic circuit breaker may be integrated to the
unit so as to remotely cut off the power supply to the house or
consumer who tries to indulge in power theft.
The ability of the proposed system to inform or send data
digitally to a remote station using wireless radio link adds a
large amount of possibilities to the way the power supply is
controlled by the electricity board.
This system will reduce the energy wastage and save a lot
for future use.
