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
