Abstract
Nowadays, technology has developed to an advanced level so customer demand for systems with automation and high security. The prepaid meter is important in making the consumer having sense about his or her energy consumption as well as in resolving the issues facing by the utility labor in getting the reading of conventional meter and eliminating the error incurred in bills issuing. This research aims to enhance an existing conventional energy meter integrate with prepaid system and protection system. The designed prepaid meter consists of an Arduino, conventional energy meter, GSM (Global System for Mobile Communications) module, current sensor and relay. The proposed prototype comprises into two parts: GSM technology and overcurrent protection, whereas GSM technology is used for communication and reloads purpose; overcurrent protection is done with a current sensor and relay working together.
