PRINCIPLE OF PREVENTING POWER THEFT
PRINCIPLE OF IMPROVING POWER QUALITY
The electricity sector in India had an installed
capacity of 237.742 GW as of February 2014, the
world's fourth largest.
India's network losses exceeded 35% including
non-technical losses out of which technical losses
is estimated to be 22.65% in 2013. compared to
world average of less than 15%.
One of the important mischief is the power theft
which is contributing a larger amount to the
nontechnical losses in transmission and
Aim of the paper is to reduce power theft and
improve the power quality by the the help of Fuzzy
Power theft could be defined as using the electricity
without paying for it basically it is stealing of
Two kinds of theft are prevalent in power systems.
1) The Meter tampering
2) The direct rigging of the distribution line
THE METER TAMPERING
Meter tampering is the method of tampering the
meter by removing it’s seal .
By-passing the meter so that a lower reading of
Standard electro-mechanical meters use a slowly
spinning disk to record the amount of power that is
being drawn , the disks can be slowed using
the prevention of power theft of this type can be
detected by placing a LDR circuit inside the meter .
THE DIRECT RIGGING OF THE
The most visible indication of energy theft occurs
when users illegally tap into the public supply.
we cannot identify the power theft automatically.
The quality of electrical power may be described as
a set of values of parameters such as
continuity of service,
variation in voltage magnitude,
transient voltages and currents
harmonic content in the waveforms.
power quality is a convenient term for many, it is the
quality of voltage which is supplied to the
consumers rather than current or power.
Fuzzy logic can be conceptualized as a
generalization of classical logic.
There are not just two alternatives but a whole
continuum of truth values for logical propositions.

EXAMPLES OF MATLAB
Result of Over-Voltage : If the voltage is 151V
then the change voltage is -151V
Result of Normal functioning: If the voltage is
230V then the change voltage is 0V.
RESULT OF POWER THEFT: VOLTAGE IS BROUGHT
THE CRITICAL VALUE IN CASE OF POWER THEFT.
Thus , the application of intelligent control in
electrical system can improve the power quality
and at the same time prevent illegal activities .
The power theft prevention would be a boom to
a country’s economy in managing the need for
