30x zoom and top solar-blind sensitivity for the professional inspector
COROCAM 7HD
Corona effect cameras
COROCAM 7HD
Professional solar-blind corona camera
Precision location of corona discharges at long range
Certified top solar-blind sensitivity
The ultraviolet channel reaches a typical sensitivity of 2.05×10-18 W/cm2, certified to IEC 60270:2000 at 1.0 pC at 15 m. An optional Non-Solar-Blind (NSB) mode keeps that same detection level for indoor or night-time work.
30x optical zoom
The visible channel reaches 30x optical zoom (58.9° to 2.11°), extendable through 4x, 6x, 8x or 12x digital zoom, with a maximum angular resolution of 0.01917 mrad that resolves the finest detail on the installation at long range.
Ergonomics for a full working day
The rotating grip, focusable and adjustable viewfinder, and flip-up LCD display let the operator hold the unit in different stances without muscle fatigue, in any lighting condition.
Detection of a corona discharge at high zoom
Ready to work without direct sunlight
The built-in LED flashlight, with adjustable brightness, and the motorised Non-Solar-Blind (NSB) module allow indoor or night-time inspections without losing detection sensitivity.
Applications and functions
Applications
- Precision inspection of highand extra-high-voltage lines and substations.
- Locating corona discharges at long range thanks to the 30x zoom.
- Indoor or night-time inspection with the Non-Solar-Blind (NSB) mode.
- Detailed diagnostics for professional inspectors who need maximum resolution.
Ultraviolet channel
The detection threshold, adjustable from 20 to 100%, and the integration time — by period, summation or noise reduction — optimise the image for the installation. The discharge is shown in 6 preset colour combinations or 100 user-selectable hues, with background priority and 0-100% transparency control.
Visible channel and location
The 1920×1080-pixel sensor offers 0.1 lux in day mode and 0.05 lux in night mode, with automatic or manual focus from 1.5 m to infinity. Internal GPS with an external booster antenna geolocates every inspection and combines with the unit's Ethernet, USB and HDMI connectivity.
Recording and sound
The unit records JPG stills and AVI 720p video to a microSD card, with a built-in microphone and speaker for adding voice notes during the inspection.
Software and post-processing
On-board recording
Images and videos, together with the camera settings for each shot, are automatically saved to the 32 GB microSD card supplied with the unit, in JPG, AVI 720p and UCF format.
Download and post-processing
Material is downloaded via card reader or USB for review and filing. The manufacturer does not specify a dedicated analysis software package for this model beyond on-unit playback and file organisation.
Field use
The icon-based menu and 10 user profiles speed up switching between inspection conditions, with boot-up to inspection mode in 6 seconds and to recording mode in 60 seconds.
