DayCor Scalar is a corona camera by Ofil that is dedicated to indoors inspections. The camera provides a clear view of corona and arcing on motors, switchgears, electrical cabinets etc., and has a powerful LED flashlight that enables inspecting very dark compartments. The device captures corona events, stores video clips and still images and has features that assist maintenance engineers get required valuable information.
One of the most destructive phenomena that exist on medium and high voltage installations is corona. Along medium and high voltage installations corona can be heard as an annoying audio noise, or it can be seen at night as a flashing violet light. At daytime corona can be seen only through dedicated corona cameras that can block daylight and transmit ultraviolet. Corona should be monitored and controlled because of its role as an aging catalyzing factor and because of the energy losses involved. The most effective way to monitor and control corona is by seeing the corona and where exactly it is emitted. Only sensitive and qualitative corona cameras can provide such reliable information.
