Abstract

Increasing energy demand encourages the utilities such as Tenaga Nasional Berhad (TNB) to improve the process of energy management and measuring energy consumption for billing purpose. The conventional meter reading is done manually whereby the utilities send human operator to every premise to take energy measurement. This requires huge number of labor work and long working hour to achieve a complete area measurement data collection. This process is not very effective when the meter is inaccessible. It is also constrained by bad weather condition. As energy demand rises due to the growing of population and industrial development, the process requires more human operators and longer working hours to complete. The problems are also arises during the event of disconnecting supply by utilities due to default bill payments since it is done manually. In order to improve overall efficiency in energy measurement process, a smart meter system is developed. The smart meter system acts as conventional energy meter but with additional features such as the system enables the utilities to retrieve the meter energy measurement data remotely via Global System for Mobile Communication (GSM). The smart meter system also allows the utilities to disconnect and reconnect supply to each and every energy meter in certain area remotely in order to save manpower consumption. The system also allows consumer to monitor their consumption by displaying voltage, current, and energy consumed in real-time. The system use Arduino Uno as a controlling unit to control contactor in disconnection and reconnection of supply and display standard electrical measurement such as voltage, current, and energy consumption using Liquid Crystal Display (LCD). The system is very suitable since GSM is widely used throughout the world. With this system, utilities can save cost in meter reading process and provide better service to their customer.
