    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. This project is designed to find out such power theft in the normal distribution lines. Even though there are certain practical problems in implementing this kind of systems in future there is a scope for development of these types of systems. This project is using the principle of the differential protection scheme for the identification of the power theft. The differential protection scheme consists of two CTs (current transformers) connected at both the terminals of the load. If there is no fault in the load then the secondary currents of both the CTs will be same. Using the same principle one CT is connected at the starting end of the distributor and the remaining other CT is connected to the different loads which are legal. If there is no power theft in the line then the vector sum of all the CT’s which are connected to the load will be equal to the current in the main ct. if there is a difference then we can make out that it should either be the power theft or a fault in the line.
