Bispectral UV and Visible Light Detection System e.g. Fire Detection
The samples shows images of a ethanol flame which has got a weak emission in the visible spectral range
and a high emission in the UV.
Visible Camera
UV Solar Blind Camera
Due to the bright daylight condition it is not
possible to detect a weak UV flame with a visible
camera.
The UV Solar Blind camera can detect the UV
radiation. Daylight shows no influence to the
camera. Therefore the weakest UV signals (up to
single photon events) can be detected.

Bispectral Camera
The overlay of visible
and UV image
achieves an exact
localisation of the

Corona Discharges at High Voltage Transmission Lines Insulators
ProxLine Cameras are especially helpful for the detection of degraded insulators at high voltage
transmission lines, distributions and substations. They are used to detect the emission of UV radiation when
discharges occur at defect insulators. ProxiLine cameras comprise a highly UV sensitive sensor to detect
discharge initiated UV radiation. The recorded image is not disturbed by intensive day light, even not by
bright sunlight. This is the superior feature of the ProxiLine family.
The ProxiLine Premium camera combines this extraordinary feature with the overlay of an image of the
situation in the visible spectrum. The overlay of both images shows the exact position of the electric
discharges. Such system makes it economical to detect defects and discharges in high voltage transmission
line insulators which helps to avoid severe and cost-intense breakdown of electricity supply.

Members of the ProxiLine Corona Detection Family
PL 4 ASB / ProxiLine ASB
The PL 4 ASB camera comprises a UV solar blind camera with optics to detect UV radiation down to the
single photon level. Ambient daylight does not disturb the images.
PL 4 Premium / ProxiLine Premium
The PL 4 Premium comprises a complete corona inspection system with a bi-spectral camera for an overlay
of an UV corona image with an visible image for an exact localisation of the faulty insulator or other source of
UV radiation in the relevant spectral range. The PL 4 Premium is a portable system operated with
rechargeable batteries and ideally suited for the outdoor powerline inspection. Furthermore a powerful
software for documentation of the inspection results considerably increases the value for the end-user. The
integration of GPS data is available as an option.

PL 4 Premium ProxiLine Corona camera
The the PL 4 Premium ProxiLine Corona camera consists of rigid housing (dimensions 230mm x 190mm x
170mm) with a” flip-up” display and a operation panel on top side. The user carries the PL4 Premium
ProxiLine camera with a strap for a good view on the display and comfortable operation and handling of the
camera. A supporting software for localisation and documentation of the inspection is included. Data which
are recorded on a data card in the camera can be easily transmitted to a PC system.
