The IWOS Overhead Line Sensor from InHand Networks is an intelligent sensing device designed for smart grid environments. With real-time wireless communication, high-precision measurements, and innovative energy harvesting, it ensures fast fault detection and improved reliability across 10kV–35kV distribution lines. It supports waveform capture, remote data access, and maintenance-free live installation, making it ideal for modern grid automation.

• Fast, Accurate Fault Location Detects and localizes faults—including low-current and high-impedance ground faults—drastically reducing outage durations and operational response times.
• AI-Driven Analytics & Fault Prediction Our cloud-based analytics platform processes waveform data to anticipate failures and notify teams via SMS or email—before outages occur.
• Real-Time Grid Intelligence Continuous monitoring of current, voltage, and fault waveforms enables load analysis, power quality evaluation, and proactive maintenance.
• Non-Intrusive, Safe Installation Hot-line installation on live 11 kV lines—no shutdowns, no service interruption.
• Self-Powered and Resilient Devices Overhead line sensors and concentrators harvest energy directly from the line or solar, ensuring 24/7 uptime.
