IoT based Power Theft Detection

Electrical power theft is a major problem in power system network all over the world, which is illegal and should be strictly prohibited. Power theft can be defined as the usage of the electrical power without any contract with the supplier. In order to eliminate power theft, the location of power theft is to be known so that appropriate action will be taken on the legal offenders. The circuit consists of Arduino, GSM, LCD, ESP module and Current transformers. Meters cannot be used for high currents so current sensing is done by current transformers. Two CTs are used, one is connected at load side to measure the current through load and other C.T is connected at supply terminals to measure the current supplied by source. Using IoT, power theft detector kit has been implemented and the same also done using GSM for the purpose of backup protection.
