CoroCAM 7

Professional Solar Blind UV Corona Camera


Download the CoroCAM 7 brochure HERE

The CoroCAM 7 is a professional grade Solar Blind, easy to operate UVc imaging system used to visualize & locate electrical discharges (corona and arcing) from High Voltage hardware. The CoroCAM 7 is typically used to inspect High Voltage infrastructure operating at 3.3 KV and above for corona discharges and arcing.

The CoroCAM 7 features the same solar blind UVc imaging system as used in the CoroCAM 6D. Advanced UVc image enhancement features are available to increase sensitivity (adjustable Long Integration & Non Solar Blind Mode*), reduce false signals (adjustable Noise Reduction & Threshold Level) and improve the visibility of the discharge indicating blob (adjustable Background Priority, Blob Transparency and Blob False Color). This world class UVc imaging system is paired with a high performance visible camera, allowing it to achieve an IFOV (Instantaneous Field of View) of 0.0477mRad for it’s visible channel, when recording UCF files.

UCF files are used to record the uncompressed displayed image & raw UVc channel, the camera settings and calibration values in one file, which can be imported by the CoroBASE Analysis and Reporting software.

The adjustable viewfinder, rotatable grip and LCD display makes for optimal ergonomics and allows the operator to use camera in all light conditions from multiple stances, minimizing muscle fatigue.
