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 is 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 control. Our purpose to 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. Index Terms—Energy theft, Energy Meter, Remote Monitoring System, Electricity Board I. INTRODUCTION Today energy consumption has become a major driving force in every body’s life. Today’s life style is supported by the way we spend/ consume energy. Many people are very aware of the energy crisis and use the energy wisely but most of the populations don’t use the energy wisely. Also energy theft is of major concern today. Electricity Board is constantly trying to deal with the energy theft problem. We are designing such a system in which Electricity Board can find out the area in which the energy theft is happening; also the amount of energy theft can be determined. II. SPECIFICATION FOR THE SYSTEM 1.1.1 Functionality provided by the system Real-time Power monitoring at houses. Detecting the power theft at the particular location . Transmitting the information over to the main substation 1.1.2 System interfaces, inputs, and outputs Energy meter: Here we using a conventional sub meter which gives the pulses to μc. the c counts these pulses to calculate the instantaneous power and displays the reading on LCD. A serial e²prom memory IC 24c04 is used to store the current reading. If the light goes the μc reads the units count and displays on LCD. An LCD display is being provided which displays the current status of the no. of units consumed. Manuscript received March 11, 2015. Pawan P. Tawade , Mahesh Raut , Kapil Marde,M.P. Gajare, Department of Electronics, AISSMS IOIT Pune-01. Two rs-485 transceivers IC are provided for communication between the ENERGY METER and . Electricity Board based device using PC. Distribution transformer: This is the main transformer unit which supplies the whole current to the total area. The idea behind the project is that the current supplied by the main transformer should be equal to the unit consumed by individual areas. The reading of all the units is sent to the Electricity Board The Electricity Board PC then monitors the reading of all the units. If the energy unit consumed by individual units is not equal to the main distribution energy units then we can conclusively assume that energy theft is taking place. Like the area1 and area2 units the mains transformer unit also has an energy meter to observe the total current consumed. All the 3 microcontrollers are connected via RS-485 LAN. The two society slaves keep sending the data to the distribution transformer unit. We also have an Electricity Board based pc unit attached. Whenever the Electricity Board requests for the readings it sends the reading of all the units, so that the Electricity Board can determine whether energy theft is going on or not. 1.1.3 Expected Outcomes Energy theft monitoring On/off of individual loads in case energy theft is detected Tampering with energy meter indication 1.2.4 System Requirement i.
