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 by passes 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.
INTRODUCTION:
Electricity is the modern man’s most convenient and useful form of
energy without which the present social infrastructure would not be feasible. The increase in per capita production is the reflection of the increase in the living standard of people. When importance of electricity is on the increasing side, then how much should theft of this energy or illegal consumption of power from the transmission lines be averted? Power theft has become a great challenge to the electricity board. The dailies report that Electricity Board suffers a total loss of 8 % in revenue due to power theft every year, which has to controlled. Our paper
identifies the Power theft and indicates it to the Electricity board through Power line. We had also dealt about the remote monitoring of an energy meter.
MICROCONTROLLER BASED AUTOMATION:
Embedded systems - a combination of software, hardware and
additional mechanical parts that together forms a component of a larger system, to perform a specific function. It’s a technology, characterized by high reliability, restricted memory footprint and real time operation associated with a narrowly defined group of functions. Automation has made the art of living comfortable and easy. Embedded systems have made the process of automation a most successful one. Here, we have focused on automotive, an area of embedded controllers, in
which we have dealt with the Power theft identification and also about the remote monitoring of an energy meter. The microcontroller chip is preprogrammed to perform a dedicated or a narrow range of functions as a part of a larger system, usually with minimal end user or operator intervention. Our paper throws light on automated monitoring of theft
identification, which is an application of embedded controllers
MODES OF THEFT:
It has been seen that there are 4 common methods of power
theft as given below :-
Bogus seals and tampering of seals.
Meter tampering, meter tilting, meter interface and
meter bypassing.Changing connection.
Direct tapping from line.
Due to introduction of modern electronic metering equipments, power
thieves are utilizing more technological methods. Recent cases of power theftdiscovered by British inspectors included customers tunneling out to roadsidemains cables and splicing into the supply, a garage taking its night time powersupply from the nearest lamp post and domestic customers drilling holes intometer boxes and attempting to stop the counter wheels from turning. Anothermethod of Power theft is by keeping a strong magnet in front of the disc inthe energy meter and thus arresting the rotation of the disc, connecting the loaddirectly to the power line bypassing the energy meter. But, it can be avoided
easily by providing a non magnetic enclosure.
