UViRCO was established in 2008 to market & manufacture the CoroCAM brand of corona cameras. The CoroCAM range of corona cameras have been produced by the CSIR since 1992.
A corona camera is used along the entire electrical power supply chain to visualise the UV emitted by external partial discharges (i.e. Corona, Sparking and Arcing) which is indicative of degraded hardware or installation / design faults.
- Generator coil insulation inspection.
- Transmission line hardware inspection.
- Distribution line hardware inspection.
- Substation hardware inspection.
CoroCAM
The CoroCAM 504 (released in 2004) is a corona camera used along the entire electric power chain, in day or night.
It is the most sensitive UV camera on the market when used in NV mode.
Thce CoroCAM 504 brought a couple of world firsts to the UV camera market, i.e.
- UV blob translucency/shading
- a removable solar blind filter, it is a motorised function
- field upgradable firmware
