The Ofil DayCor® Superb-OD Portable Daytime Corona Camera can be used to record corona and arcing.
It includes a bi-spectral, solar-blind, UV-Visible camera which will remain operational in daylight and features a high signal to background ratio. This camera has been developed from DayCor’s® patented technology and is particularly sensitive to surface partial discharge. It is able to detect UV radiation from corona emissions which are as weak as 1pC from a distance of 10m and detects RIV of 7.7dBµV at 1MHz. The Ofil DayCor® Superb-OD Portable Daytime Corona Camera displays both these signals and their emitting sources, accurately overlapping the information and indicating the strength of the corona.
Its UV events counter also works to indicate the strength of detected corona as it monitors and records the number of UV events within a given time period in order to determine corona intensity.
The Ofil DayCor® Superb-OD Portable Daytime Corona Camera includes a selection of exclusive lenses and is capable of digital UV zoom, quick visible zoom and includes autofocus for both the visible and UV channels. This combination of features and lenses ensures that the user is able to easily and accurately pinpoint the location of the corona, whether from a distance or at close range.
The images and videos captured using the Ofil DayCor® Superb-OD Portable Daytime Corona Camera can be viewed via its foldable, transflective 5-inch screen with adjustable bright colour LCD. (PLEASE NOTE, this instrument has a sister product, the Ofil DayCor® Superb-XD Portable Daytime Corona Camera, which features a slightly larger display). This display has been optimised for outdoor use and for sharing images/ footage with team members.
Alternatively; media captured using the Ofil DayCor® Superb-OD Camera can be saved, with audio notes, to the removable, compact flash card for consultation and/or playback at a later date.
The Ofil DayCor® Superb-OD Portable Daytime Corona Camera has been ergonomically designed. It is lightweight, rugged and includes a supporting harness that has been anatomically fitted to distribute the camera’s weight evenly; this ensures that the camera is easy to handle and prevents the hand, back and eye strains that often accompany continuous use.
The user may operate the Ofil DayCor® Superb-OD Portable Daytime Corona Camera using its keyboard. The keyboard includes direct access to frequently used functions; once a function has been selected it is indicated on the camera’s aforementioned foldable display. This facilitates clear, easy operation of the instrument.
The Ofil DayCor® Superb-OD Portable Daytime Corona Camera’s design, features and sensitivity make it the ideal instrument for non-destructive testing and inspection of high and medium voltage equipment, including overhead transmission and distribution lines and substations.
