Distribution Overhead Line Monitoring & Analytics
Fault Detection, AI-enabled Preventive Grid Analytics
Consisting of overhead line sensor, concentrator and analytics platform, the Intelligent Wireless Observing System (IWOS) helps utilities detect & locate faults, reduce power outage, and move from reactive to preventive maintenance. The IWOS is field proven by more than 180,000 line sensors installations by 2020. Leveraging big data analytics and artificial intelligence, the IWOS has accumulated more than 28 million waveform data of line events and successfully detected more than 35,000 faults including ground faults, short circuit faults, inrush current, lightning, and more.
