UV RADIATION DETECTION

Introduction:

The SONEL UV-260 is a high-end, professional yet lightweight and intuitive device designed for fast, simple and non-invasive remote diagnostics of electrical installations. Its advanced imaging system and highly sensitive UV detector enable users to observe and record electrical discharge phenomena in both ultraviolet (UV) and visible light. The UV-260 is specifically designed for the detection and monitoring of corona, arc and surface discharges in power engineering. It provides an effective method for continuously assessing the technical condition of electrical equipment, including high-voltage (HV) power lines and enables potential problems to be identified and precisely located before they develop into serious damage or major failures.

When inspecting complex and extensive power systems, accurately determining the location of a potential fault or discharge source can be challenging. The UV-260 addresses this issue with a built-in GPS receiver, which automatically records the geographical location associated with captured photographs and video recordings. This facilitates precise identification and documentation of discharge sources during inspections.

Key Features:

• High UV sensitivity for reliable detection of corona, arc and surface discharges.
• Dual UV and visible-light imaging for comprehensive inspection and analysis.
• Photo and video recording, with the ability to save and replay captured images and video clips.
• Built-in GPS receiver for precise geographical location of recorded events.
• Automatic focusing for both UV and visible-light images.
• Automatic noise reduction for clearer and more detailed images.
• 5.7-inch touch LCD for intuitive and convenient operation.
• Daylight operation without sensitivity to sunlight, allowing inspections to be performed effectively in full daylight.
• LED alarm indicator to provide an immediate visual alert when UV radiation is detected.
• Non-invasive diagnostics, allowing inspections to be carried out without interrupting equipment operation.
• Data-transfer and reporting software for efficient analysis, documentation and generation of inspection reports.

With its combination of advanced UV detection, high-quality imaging, GPS-based location recording and intuitive operation, the SONEL UV-260 provides a comprehensive solution for preventive maintenance and condition monitoring of high-voltage electrical infrastructure.
