- 1. CHAPTER NO: 01 INTRODUCTION 1.0 INTRODUCTION Electricity Theft is a very common problem in countries like Pakistan, where population is high and the users of electricity are ultimately tremendous. In Pakistan, every year there is a very increasing no of electricity thefts across domestic electricity connections as well as industrial electricity supply, which results in loss of electricity companies energy and because of which we are facing the frequent problems of load shading in urban as well as rural area so as to overcome the need of electricity for whole state. Also the ways using which theft can be done are also innumerable so we can never keep track of how a theft has occurred, and this issue is needed to be solved as early as possible. 1.1 Problem Statement In this project, we propose an electricity theft detection system and meter monitoring system by using GSM and Arduino microcontroller to detect the theft which is made by the most common way of doing the theft and that is bypassing the meter using a piece of wire, people simply bypasses the electricity meter which is counting the current units by placing a wire before and after the meter reading unit. The proposed system will be hidden in such meters and as soon as an attempt is made for the theft, it will send an SMS to control unit of electricity board and after few seconds disconnect the power automatically.In this project, a consumer can switch on and off its house load, and also check out the current status of the energy meter by simply sending an SMS to the GSM system of the energy meter.

If there is any different value means by comparing both powers, P1 and P2 it is indicated that the particular pole has drawn more current as theft. Here one current sensor is placed in input side of the post line. Other current sensor are placed at the distribution points of the house lines. The output of current sensors values is given as input to Arduino microcontroller. Arduino microcontroller converts these analog inputs into digital using inbuilt ADC converter. Then Arduino microcontroller compares the input current and the sum of output currents. If compared result has any difference value then this particular post is detected as theft point. This compared value is transmitted to electricity board through RF transmitter. RF receiver is placed in electricity board office. This RF receiver receives this value and given as input to Arduino microcontroller. Arduino microcontroller displays this value in LCD display. The information will then be quickly processed by the microcontroller and a SMS will be sent through the GSM technology. ERROR SIGNAL= P1-P2 Following are main objectives of the project (1) To detect power theft by receiving an SMS on control room. (2) To take action automatically against theft after few seconds. (3) To monitor the energy meter of consumer without going on the spot of service man. (4) To turn on and off house load by sending an SMS to the GSM based energy meter. (5) To get current unit status as well as after month by simply an SMS.
