UVIRSYS – Precision Imaging Solutions for Electrical Asset Diagnostics

UVIRSYS (Shanghai Zihong Optoelectronics Technology Co., Ltd.) is a specialized technology company focused on the development and manufacturing of advanced ultraviolet (UV), infrared (IR), and multi-spectral imaging systems for the live detection and fault diagnosis of high-voltage electrical equipment.

With deep expertise in corona discharge detection and thermal imaging, UVIRSYS provides power utilities, industrial facilities, inspection contractors, and maintenance teams with practical, high-performance tools to identify invisible defects before they escalate into failures.

Complete Portfolio of Imaging Solutions

UVIRSYS offers a comprehensive range of portable, drone-mounted, robotic, and online monitoring solutions:

• ZH480 Series Corona Detection Cameras High-sensitivity UV imagers designed specifically for corona and partial discharge detection. The portable ZH480 and ZH480-PRO models feature innovative dual field-of-view (wide-angle + telephoto) lenses, allowing inspectors to efficiently scan both close-range substation equipment and distant transmission line components without changing lenses. These cameras deliver precise photon counting, accurate image fusion, and quantitative corona assessment in a compact, ergonomic design.
• ZH580 Multi-Spectral (UV + IR + VIS) Cameras Advanced three-channel imagers that simultaneously capture corona discharges (solar-blind UV), surface temperature anomalies (IR), and high-resolution visible context. The ZH580 portable model and its drone-integrated variant (ZH580-UAV-S) provide real-time multi-spectral fusion with exceptional overlay accuracy, multiple display modes, and powerful diagnostic capabilities in a single device.
• Drone-Borne & Robotic Inspection Systems Specialized UAV payloads (ZH480-UAV and ZH580-UAV-S) and substation inspection robots (such as the ZH580-AIBO series) that bring advanced UV and multi-spectral imaging to aerial and automated inspection workflows. These solutions enable safe, efficient monitoring of transmission lines, towers, substations, and hard-to-reach assets.
• Infrared Thermal Imagers & Intelligent Analysis Systems High-performance thermal imaging solutions paired with intelligent temperature analysis software for predictive maintenance and hot-spot detection across power infrastructure.
• Online Monitoring & Substation Intelligent Inspection Systems Fixed and semi-permanent monitoring solutions designed for continuous surveillance of critical electrical assets, supporting condition-based maintenance strategies.

Professional Services

Beyond hardware, UVIRSYS offers expert testing and inspection services, including:

• UV corona detection testing
• Infrared thermography services
• Drone-based aerial inspections

These services help clients implement effective condition monitoring programs with reliable, standards-aligned reporting.

Mission & Value

UVIRSYS is committed to making advanced corona detection and multi-spectral imaging technology more accessible and practical for field use. By combining high sensitivity, precise multi-spectral fusion, rugged portability, and intelligent analysis, their solutions enable faster, safer, and more accurate inspections of substations, transformers, switchgear, transmission lines, and other high-voltage equipment.

Whether used for routine maintenance, predictive diagnostics, or specialized inspection projects, UVIRSYS systems help utilities and industrial operators improve reliability, reduce unplanned outages, and enhance operational safety.
