Smart energy grid technology firm CAHORS Group has integrated LoRa and LoRaWAN technologies from analogue and mixed-signal specialist Semtech Corporation. The LoRa technology is being incorporated into CAHORS' new Sentinel line fault detection solutions. They will support more accurate line fault detection in smart grid networks.

Installed on power line support poles, CAHORS’ LoRa-based Sentinel products monitor voltage field transfer to locate and predict faults in power lines, including single phase grounded faults and multiple phase fugitive and ongoing faults. Sensors identify failures in real time, and transmit energy flow data (fault direction) through LoRaWAN networks to energy grid managers. Managers evaluate the fault data for localisation of the faulty section, enabling a quick response to ongoing faults, increasing overall grid efficiency and preventing power outages.

“CAHORS identified Semtech’s LoRa devices and the LoRaWAN protocol as the Internet of Things (IoT) platform offering the proven capabilities to digitise network grids,” said Christophe Aubigny, Director of Product Strategy at CAHORS. “Our new Sentinel solutions continuously monitor a grid MV network in overhead voltage lines, and leverage LoRa devices’ long range and low power capabilities to transmit fault data in real time. Accurate, up-to-date data on grid functionality allows customers to detect, locate and address grid faults more efficiently and prevent costly system failures.”

“With the increased digitisation of smart grids, electricity utilities are seeking smarter applications to simplify integration and deployment,” said Rémi Demerlé, Director of Vertical Marketing for Utilities in Semtech’s Wireless and Sensing Products Group. “Semtech’s LoRa represents a leading technology for the smart utilities vertical market, creating metering solutions that are flexible, scalable, easy to use, and deploy. LoRa devices accelerate IoT solutions to market that offer customers the capacity to reduce operational expenses and create new efficiencies.”
