Communication Technologies Comparison for Electric Power Quality Monitoring - Fuse Sensor

The electrical energy quality is affected by factors such as faults and interruptions, and energy concessionaires have been looking for ways to innovate, control and mitigate the causes that affect the electrical energy quality and making the network more reliable. In this way, the concessionaire has implemented the IoT (Internet of Things) concept and the Smart Grid (Smart Electricity Grids) in its energy distribution networks. The modernization of communications networks, provided that the connection of IoT applications were made through LPWAN technologies in the sub GHz bands and FSK modulation that offers low energy consumption and long range in its physical layers. Thus, this article presents, analyzes and compares LPWAN technologies such as LoRa and SigFox and also on FSK technology for coverage tests in some regions in the state of Espírito Santo, Brazil. From the preliminary results obtained taking into account the chosen test sites, it was observed that LoRa technologies presented better results in communication and coverage in relation to SigFox and FSK technologies.
