Find out if partial discharge from corona is corroding your HV infrastructure.
Corona emits energy in the ultraviolet spectrum. The human eye can't seen UV but the Sonel UV-260 Corona Camera can.
And it can distinguish UV corona even in daylight.
UV radiation emissions will show up superimposed on the visible camcorder image so you can precisely locate the source.
Take an image snapshot, or record a video. A UV-photon volume counter helps you determine the severity.
Try it out on your system. The UV-260 is available for rent. Ask us about drone applications.
