Detect Corona Discharge Before It Becomes a Failure
Corona discharge emits faint UV radiation (240–280 nm) invisible to the human eye. The ZH480-AIBO captures and overlays that UV signal onto a 1920×1080 HD visible image in real time, locating defects with pinpoint accuracy even in direct sunlight. With sensitivity down to 1pC at 10 meters and real-time photon counting, it quantifies fault severity to enable true condition-based maintenance.

The Corona Detection Imaging System for Robot Dog UV+VIS by UVIRSYS brings next-generation electrical fault detection to an agile, four-legged robotic platform. By fusing solar-blind ultraviolet (UV) and high-definition visible (VIS) imaging, it autonomously detects corona discharge and partial discharge activity — the invisible precursors to catastrophic equipment failure — with pinpoint accuracy across substations and power infrastructure.

Corona discharge emits faint UV radiation (240–280 nm) that is completely invisible to the human eye. This system captures and overlays that UV signal onto a 1920×1080 HD visible image in real time, precisely locating defects even in direct sunlight thanks to its out-of-band rejection filter. Discharges as low as 1pC at 10 meters are detectable — catching failures before they happen.

Intelligent Inspection Platform
Beyond imaging, the system integrates with a centralized inspection management platform for automated, data-driven reporting. LIDAR navigation enables fully autonomous patrol routes, while real-time photon counting quantifies corona severity — enabling condition-based maintenance decisions that reduce unnecessary field visits and prevent unplanned outages.
Built for Power Infrastructure
Designed to address the core challenges of modern grid management, the UVIRSYS robot dog system enhances personnel safety by keeping technicians away from energized equipment, improves data reliability through consistent autonomous inspection, and maximizes operational efficiency with automated reporting. As UVIRSYS puts it: "All power defects, nowhere to hide."
