SigFox based Voltage Monitoring System for Pole Mount Distribution Transformer

Abstract

Knowing the status of variable parameters in a power distribution system is of paramount importance especially to the power supply utilities since it can allow them to act proficiently when the need arises. The design and development of a real time IoT based voltage monitoring system for pole mount distribution transformer has been addressed in this paper. The established device has the capabilities of sensing, measuring and monitoring phase to neutral voltages for distribution transformer output and also the locality of the transformer. Accordingly, it has a smart sensing unit that detects under voltage, over voltage and power outage. Furthermore, Sigfox network for data transmission to Azure cloud for visualizations and analysis has been employed in the establishment of the complete system. The developed prototype was extensively tested and experimental results have been compared with the convectional measuring devices. The results confirm the practical applicability of the designed system device. Implementations of this device in the power distribution network can greatly improve on system reliability since voltage fluctuations can be monitored effectively on real time
