Abstract
Electrical energy is very important for our day today life. When the population increases the power utilization also increases as well as the energy theft is also increases. Utilities in electricity system are destroying the amounts of revenue each year due to energy theft. The newly designed Atmega 328 microcontroller used for energy measurements reveal the concept and working of new automated power metering system but this increased the Electricity theft forms administrative losses due to not regular checkout at the consumer's residence. It is quite impossible to check and solve out theft by going every customer’s door to door. In this paper, a new procedure is followed based on Atmega328P microcontroller to detect and control the energy meter from power theft and solve it by Relay disconnect and reconnecting the service line of a particular consumer. An SMS will be sent automatically to the utility central server through GSM module whenever unauthorized activities detected and a relay was in order to disconnect the unauthorized supply. A new method is implemented by interspersed the GSM feature into smart meters with Solid state relay to deal with the nontechnical losses.
