DayCor® Solar Blind UV Technology
DayCor® technology detects corona and arcing by capturing ultraviolet emissions in the solar blind spectrum, below 280nm. In this range, sunlight is naturally blocked by the Earth’s atmosphere, allowing precise detection in full daylight without interference. By isolating this specific UV band, DayCor® cameras reveal electrical discharges that are invisible to the human eye, supporting early fault detection and effective maintenance.
UV and Infrared Technology
UV Diagnostic is suitable mainly for problems related to voltage distribution, or surface voltage gradient, while the IR diagnostic can be used mostly for problems connected with current overheating. A combination of UV, IR and visual diagnostics increases the reliability of diagnosis and can help at inspection results evaluation.
