Still there are some villages in the country do not have 24 hours electric power that is there is a shortage of electricity and this lack of power supply is directly impacting on the country’s economic growth. The electricity sector plays a major role in Indian economy. The project is mainly focuses on both hardware and software. The project implements power theft detection and other management services such as voice announcement facility to the concerned department, finding location of power theft, plotting GPS points in google maps, auto police complaint to the nearest police station, power theft location sharing to police and finally capturing photos remotely for proof of theft. Our project consists of SMS enabled application and voice-based application. This project will also consist of the following features such as object detection on the power line and power grid, measuring temperature in the transformer such as high and low and measuring oil level in the transformer. Measuring temperature and oil level in the transformer and taking necessary actions will lead to improve power transmission and it also boosts transformer efficiency. Keywords: Microcontroller, GSM, IR Sensor, Temperature Sensor, Current Sensor, Relay, ADC, etc. 1. INTRODUCTION Transmission power lines are built to transfer electric power from power source locations to power distribution networks. The transmission power line lengths are exposed to different faults and errors. The error rate is very high in transmission power lines. Faults and errors on power system transmission lines need to be identified and located very speedily, classified perfectly and cleared as fast as possible. At present India is losing more than 55,000 crore rupees every year due to poor transmission and distribution system. If we could save 1% out of it will be a good profit to the power sector and nature can be retained for some more extent. When all the said above things works better on line, we can save power. Unfortunately, all are not in a single roof and not possible in a single roof because it is a network of about thousands of kilometres. When we analyse the above said matters a common objective system is needed to remove the unwanted barriers of the power sector. Here we would like to automate the power theft detection system to overcome the problems we have stated above, and it helps in reducing power loss, to save the time thereby saving the cost. The embedded technology will be used in our project to minimize the electronic hardware components. Embedded technology is used to minimize the cost and maximizing the work ability. Embedded systems will provide the needs of industrial control, monitoring, interfacing with any latest communication systems like GSM, IR, BLUETOOTH, MICROCONTROLLER etc. This project is helpful in power theft detection from intruders and provide various management services such as voice announcement to the concerned department, detecting power theft location, provides facility to plot power theft location on google maps, automatic police complaint through online, capturing photos remotely for proof of theft. Overall this project improves power transmission by monitoring transformer temperature and oil level in the transformer using corresponding sensors. It is a IoT CLOUD based project. 1.1 Description of components 1.1.1 Microcontroller The SST89E516RD is a 8-bit microcontroller product manufactured by CMOS semiconductor technology. It offers significant cost and reliability for customers by using split gate cell design and thick-oxide tunneling injector. The instruction set used is 8051 and it has more random access memory and read only memory capacity. It also has 3 timers.
