Handheld Corona Detection Camera *UV+VIS*

In the high-stakes world of high-voltage asset management, invisible problems can lead to catastrophic failures. The UViRSys Handheld Corona Detection Camera is the ultimate predictive maintenance tool, engineered to detect, pinpoint, and document partial discharge and corona emissions long before they result in flashovers, insulation breakdown, or costly outages.

By fusing cutting-edge solar-blind Ultraviolet (UV) technology with high-definition Visible (VIS) light imaging, the UViRSys camera allows field technicians to visualize the invisible enemy in real-time.

Traditional infrared cameras detect heat only after a defect is well-developed. The UViRSys system detects the early onset of ionization. This handheld device merges two live video streams with absolute precision:

• High-Sensitivity UV Channel: Detects faint corona discharge signals in the 240–280 nm solar-blind spectrum, completely immune to solar interference, ensuring accurate detection even in bright daylight.

• HD Visible Channel: Provides a sharp, real-time visual context of the equipment under inspection, allowing you to instantly localize the exact source of the discharge on insulators, conductors, or switchgear.

Key Features & Operational Benefits

• Zero False Positives (Solar-Blind Technology): The advanced UV sensor filters out the sun’s UV radiation completely. There is no need to wait for overcast weather or darkness; the UViRSys camera delivers accurate diagnostic data in full daylight.

• Precise Defect Localization: The automated overlay mode superimposes the UV discharge "cloud" directly onto the visible image. If you can see the asset, you can see exactly where the corona is forming—right down to a specific insulator shed or a sharp edge on a busbar.

• Quantifiable Discharge Assessment: Move beyond simple “yes/no” detection. The on-screen UV photon counting provides a direct correlation to the intensity of the discharge, allowing you to trend degradation over time and prioritize repairs based on severity (e.g., following IEEE standards).

• Ergonomic, True One-Person Operation: Designed for demanding field inspections across substations and transmission lines, the lightweight, ruggedized body features a one-button operation philosophy, a high-resolution flip-out LCD, and a pistol-grip design for fatigue-free, all-day scanning.

• Dynamic Recording & Voice Annotation: Capture critical findings instantly. Integrated video recording stores fused UV+VIS footage directly to an SD card, complete with voice annotation to ensure that inspection notes are permanently linked to the visual evidence.

Critical Applications

• Transmission & Distribution Lines: Identify failing composite and porcelain insulators, missing corona rings, and damaged conductor strands.

• Substations: Scan for discharge on bushings, CTs, PTs, standoff insulators, and switchgear cabinets.

• Electrical Manufacturing: R&D testing of medium and high-voltage components to identify design flaws.

• Wind Power & Railways: Inspect slip rings, generators, and overhead catenary systems.

The UViRSys Advantage

Don't rely on acoustic guns that struggle in noisy substations or thermography that catches problems too late. The UViRSys Handheld Corona Camera provides the earliest possible warning. It transforms condition-based maintenance from a reactive calendar exercise into a precision, risk-based strategy.

Save downtime. Prevent outages. Detect it before it destroys.
