CAHORS selects Semtech’s LoRa devices for accurate line fault detection in smart grids

CAHORS Group has integrated Semtech’s LoRa devices and the LoRaWAN protocol into its new Sentinel line fault detection solutions for simplified defect monitoring 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 can then 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.”

IoT networks based on the LoRaWAN specification have been deployed in 100 countries and Semtech is a founding member of the LoRa Alliance, the fastest growing IoT Alliance for Low Power Wide Area Network applications.
