We develop robust cameras for switchgear imaging in high and medium voltage systems. These applications require an extremely shock and EMC resistant design as well as high temperature resistance.
In numerous countries, visible isolating gaps in switchgears constitute a recognized and regulated safety concern. Clients need to install appropriate cameras, fitted with adapters, at all viewports in order to fully visualize the isolation gap in gas insulated switchgears.
With only one opening in the viewport for illumination and image acquisition, a specialized, extremely small housing design must be perfectly aligned to the mechanical interfaces at the client’s site. Special adaptation of the signal processing for the lighting requirements at the client site, such as an integrated, individually controllable LED illumination concept for every camera, and with minimization of reflection of glass and metal surfaces.
Difficult conditions arise from electromagnetic interference and shock/vibration due to proximity to high and peak voltages. Image retrieval is possible either at the facility site or via transmission of the images to a control room. Integration into the client’s system with a specific viewer software is also possible.
In every case, the foundation of Kappa’s solutions is an extremely compact camera module with a CMOS sensor and Global Shutter, in a housing developed especially for adaptation to viewports, with client-defined attachment options. These cameras, with typical "Rugged Design by Kappa", are designed for operating temperatures from -20°C to +80°C (-4°F to -112°F) and deliver absolutely reliable high image quality even under more difficult electromagnetic conditions.
Various illumination concepts are available and are optimized for every type of system. As an example: LED illumination is integrated into the camera module. An optimal alignment is preset for every viewport. The user can control the LEDs individually via the viewer software, ensuring images with differing reflection effects while verifying the live image quality.
For this type of use, USB or FireWire are ideal as high-capacity, economical interfaces.
We offer specific concepts according to clients’ requirements. Integration into the client’s system with specific viewer software is possible. Image retrieval is possible either at the facility site or by remote transmission to a control room.
The included software can be installed on a commercially available laptop. The user can view the live images from each camera and control the LED illumination on the camera. Live images are calibrated against reference images stored in a data bank. The images can then be embedded in reports and into the filing system.
