This paper presents a design of secure and economical (low cost) way of GPRS based fully automated energy metering system that measures and transmits the total electrical energy consumption to main server using general packet radio service (GPRS) technology provided by GSM networks and also present how the meter reading, disconnection and reconnection can be controlled from server end. The proposed EGFAEM system consist of four main parts: Energy Meters, Communication part over GPRS, Server and Management part and consumer end for billing and payment. A single phase energy meter prototype has been implemented to provide measurement up to 40A load current and 230V line to neutral voltage. Communication part is implemented by GPRS module and microcontroller, sever and consumer end are implemented in web server.
