ABOUT NSIC:

The National Small Industries Corporation Limited (NSIC) was

established in 1955 by the Government of India.

NSIC provides diversified support through its wide spectrum of

programs to TSC to cater to their different needs related to multi-

products and multi-locations markets.

INTRODUCTION:

Power theft is at the centre of focus all over the world but power theft

in India has a significant effect on the Indian economy, as this figure

is considerably high.

The present thesis, Microcontroller Based Power Theft Identifier,

introduces the concept of preventing the illegal usage of the electrical

power.

4

WAYS OF POWER THEFT:

The normal practice for power theft is to short the input and

output terminals

To place a magnet on the wheel in case of old meters.

Bogus seals and tampering of seals.

Disturbing electronic common reference point of

measurement.

GSM:

GSM (Global System for Mobile communications) is a cellular

network, which means that mobile phones connect to it by searching

for cells in the immediate vicinity.

GSM networks operate in four different frequency ranges. Most GSM

networks operate in the 900 MHz or 1800 MHz bands.

Some countries in the Americas use the 850 MHz and 1900 MHz

bands because the 900 and 1800 MHz frequency bands were

already allocated.

MICROCONTROLLER:

A microcontroller is a computer on a chip. It is an integrated chip that

is usually a part of an embedded system. It is a self contained,

independent and yet function as a tiny, dedicated computer.

9

MAX 232:

A MAX232 chip has long been using in many microcontrollers

boards. It is a dual RS232 receiver / transmitter that meets all RS232

specifications while using only +5V power supply.

10

TOUCH SENSOR:

Touch Sensor Technologies designs and manufactures patented

digital switches for use in touch-sensitive User Interface Panels.

Much more durable than mechanical and membrane switches, Touch

Sensor keypads have become the new standard for solid-state

switching.

11

LCD:

A liquid crystal display (LCD) is a thin, flat display device made up of

any number of color or monochrome pixels arrayed in front of a light

source or reflector.

12

POWER SUPPLY:

13

Power supply is a reference to a source of electrical power. A device or

system that supplies electrical or other types of energy to an output load or

group of loads is called a power supply unit.

CAPACITORS:

A capacitor or condenser is a passive electronic component

consisting of a pair of conductors separated by a dielectric.

14

RESISTORS:

A resistor is a two-terminal electronic component that produces a

voltage across its terminals that is proportional to the electric current

through it in accordance with Ohm's law: V = IR

15

VOLTAGE REGULATOR:

A voltage regulator is an electrical regulator designed to automatically

maintain a constant voltage level.

It may use an electromechanical mechanism, or passive or active electronic

components.

APPLICATIONS:

The system can be incorporated for almost all types of users.

The concept is well suited especially for villages and interior

areas.

We by this design like to conclude that the power theft can be

effectively curbed by detecting where the power theft occurs

inform the authorities.

20

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.

Automatic user identification.

21

LIMITATIONS:

Wide range of frequencies is required to facilitate large

number of users. To overcome this, carrier levels can be

changed from region to region.

Presently, it requires a power supply (230 V) for the operation,

but a small battery with automatic charging facility can be

provided in real time.

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 lot of time and

manual input.22

CONCLUSION:

The project of ours is aimed at reducing the heavy power and

revenue loss that occur due to power theft by the consumers.

The proposed system will be hidden in such meters and as soon as

an attempt is made for the theft, it will send a sms using GSM

modem, by displaying the respective consumer meter number to

control unit of electricity board

Thus by the above mentioned design we can successfully and

effectively address the problems related to power theft.
