ABSTRACT

Science and technology with all its miraculous advancements has fascinated human life

to a great extent that imagining a world without these innovations is hardly possible. While

technology is on the raising slope, we should also note the increasing immoral activities. With a

technical view, “Power Theft” is a non-ignorable crime that is highly prevalent, and at the same

time it directly affects the economy of a nation. Data collected over Tirunelveli District, Bhel

Trichy proves the necessity of this project.

Detecting and eradicating such crimes with the assistance of the developing scientific

field is the “Need of the Hour”. With these views was this paper conceived and designed. Our

paper provides a complete and comprehensive tool to prevent power theft which is very simple

to understand and easy to implement(Accepted by T.N.E.B officials). It includes four sections –

transmitting, receiving, counter display and processing sections.

DESCRIPTION OF OUR IMPLEMENTATION IDEAS:

The disc revolutions are sensed into pulses by optical slot sensor. These pulses are shaped

and given as control signal to the CMOS switch which bypasses carrier wave generated by PLL

provides as input to receiving section where transmitted signal is selected by the Intermediate

frequency transformer. For each lock a pulse is sent out. The counter section is designed to send

out pulse for every six input pulse from the receiver section. This count is parallely distributed

in a 7-segmentdisplay and then to μc for further processing. μc performs the function of

indication and identification. Pindetails, features, connections and software employed for

μc89c51 are described in detail.

We believe our implementation ideas is a boon to the electricity board offering them a

chance to detect accurately the location and amount of power theft. Logical view for a digital

meter is also included in our presentation.
