Corona & UV Testing

Corona is an emission that can weaken insulators due to too much voltage stress.  It can be visible as a purple glow of light and can often be heard as a splintering noise and can lead to audio noise, radio & TV interference and electrical mechanical failures and also can give off static electricity and ozone production.  Corona effects electric power transmissions, transformers, capacitors, electric motors and generators.  A combination of UV and infrared sensors can detect and pinpoint corona discharge so that the issues with the equipment can be addressed and fixed.

Berg offers UV cameras which can detect the causes of corona.  These range from airborne systems, handheld systems and vehicle mounted systems. Ofil Systems is the leading brand dealing with corona detection.  Browse our categories to find which corona testing solution best fits your needs.
