Technical Specification
  • Description

    Innovative solution for the detection of UV emissions

    The design with emphasis on high functionality allows detection and monitoring of corona, arc and surface discharges in the power industry. It is a method for ongoing analysis of the technical condition of equipment, for example HV lines, and for locating problems before damage or major breakdowns occur.

    UV-260 is a high-end, professional, yet lightweight and intuitive device, allowing for simple and fast remote diagnosis of installations without the need to interfere with their operation. Due to its latest generation imaging system and highly sensitive UV detector, the product allows events to be observed and recorded under both visible and UV light. In addition, images can be saved as photos or videos.

    In the case of complex and extensive testing of power systems, i.e. power lines, it is a major problem to determine the potential failure area accurately. This is why Sonel has opted for a comprehensive solution. UV-260 has a built-in GPS receiver, recording the location of the photo or video taken.


    • Precise location of discharge sources

    • High UV sensitivity
    • Automatic sharpness for UV and visible image
    • Automatic noise reduction
    • 5.7” touch LCD
    • No sensitivity to sunlight during operation in full daylight
    • Additional LED alarm in the event of UV radiation detection
    • Built-in GPS
    • Software for data transmission and generating reports


    The design, placing emphasis on high functionality, allows for detection and monitoring of corona, arc and surface discharges in power engineering. This is a way to continuously analyze the technical condition of equipment - e.g. an HV power line - and locate problems before damage or serious failure occurs.
