Small and
battery operated, the CoronaFinder is easy to take to the field. Real
time UV viewing means that high voltage equipment can be quickly and
thoroughly inspected for evidence of corona discharge that is visible
only in the ultraviolet spectrum (see photograph below). Clearly
identifiable corona discharge seen with the CoronaFinder can be
photographed with an optional digital camera that attaches to
the CoronaFinder. Click on the following link to "youtube"
for video footage of a corona test inspection.
