MARBENUS 3 Prototype

Abstract

             Energy monitoring is a way of determining the trend of energy utilization. It is an activity that could increase the awareness on the organizational base costs and enables a significant company-wide money-saving decision. The traditional approach takes regular readings on a kilo-watt hour meter at fixed time intervals. This method is very manual, time consuming, and is prone to error. An alternative approach is developed were labor-saving means of monitoring power, and trending usage can now be performed at a centralized level. This study intends to improve the traditional scheme of monitoring electrical energy utilization by using a sensor network. A sensor node prototype was constructed based from its model architecture. Voltage and current samples from a three-phase electrical network are processed by the sensor node and information is transmitted using UDP/IP to the base node were it would display data readings. The power measurement accuracy of the sensor node reaches up to about 98% on its operating range which is 220V ±20% and 5A to 200A. Energy accumulation accuracy declined to about 90% due to ineffective data transmission to the base node. However, the system can be used satisfactorily for monitoring energy utilization in real-time.
