Power grid systems are considered as critical infrastructure that require smooth and efficient operation in its power generation, transmission and distribution sectors. A performance loss in such systems can lead towards undesired situations including damages and financial losses. Remote, reliable and real-time monitoring of different components within a power grid system are important features for assuring performance, especially in modern smart grid technologies. Internet of Things (IoT)-enabled monitoring systems have the potential to fulfill the said requirements. For that, adopting a suitable communication technology to effectively transfer data of the monitored component is an essential design objective in IoT-enabled monitoring systems. This paper proposes a prototype design suitable for remotely monitoring different components within a power grid while adopting ZigBee as the underlying communication technology. Experimental results show that the devised prototype has the potential to effectively capture and notify in real-time the changes occurring in a power grid system.
