The Ofil DayCor® Superb-XD Portable Daytime Corona Camera is a non-destructive instrument suitable for testing and inspecting high and medium voltage equipment such as overhead transmission and distribution lines and substations.
The Ofil DayCor® Superb-XD Portable Daytime Corona Camera includes a slightly larger foldable, transflective screen, with adjustable bright colour LCD, than its sister product the Ofil DayCor® Superb-OD Portable Daytime Corona Camera. Whereas the Superb-OD has a 5-inch screen the Superb-XD has a 6.5-inch screen. The large, foldable screen is designed to be suitable for use outside and for sharing images and footage with surrounding team members.
The display allows the user to view the captured images and footage in a sharp, clear resolution. It also works in conjunction with the Ofil DayCor® Superb-XD’s keyboard to facilitate quick and easy operation of the instrument: once a function has been selected using the function buttons on the keyboard it is displayed on the screen.
In addition to being easy-to-use, the Ofil DayCor® Superb-XD Portable Daytime Corona Camera is also ergonomically and ruggedly designed. It is suitable for use across a range of indoor and outdoor environments and is both lightweight and supplied with an anatomically form-fitted harness. This harness has been designed to distribute the camera’s weight evenly, thereby working to prevent the back, hand and eye strains which usually accompany prolonged usage.
The Ofil DayCor® Superb-XD Portable Daytime Corona Camera includes a bi-spectral, solar-blind, UV-Visible camera with a high signal to background ratio facilitating increased sensitivity to UV radiation, even during complete daylight. This camera is able to detect UV radiation from corona emissions which are as low as 1pC from a distance of 10m. It is also capable of detecting RIV at 7.7dBµV at 1MHz. The Ofil DayCor® Superb-XD Portable Daytime Corona Camera will display both of the aforementioned signals and their respective emitting sources; it is also capable of accurately overlapping this information and indicating the strength of the detected corona. This two-channel camera has been developed using DayCor’s® patented technology which ensures that it is particularly sensitive to surface partial discharge and ideal for recording corona and arcing.
In addition to its high-sensitivity, the Ofil DayCor® Superb-XD Portable Daytime Corona Camera features autofocus on its the UV and visible channels. It also includes digital UV zoom and rapid optical zoom as well as a selection of exclusive lenses. This instrument’s camera design, features and lenses ensure that the user is able to easily and accurately locate corona at both close and long ranges.
The images and videos captured using the Ofil DayCor® Superb-XD Portable Daytime Corona Camera may be viewed on the display (as previously mentioned) or can be saved, with audio notes, to the removable, compact flash card. The media saved to this card can be played back at a later date.
Finally, the Ofil DayCor® Superb-XD Portable Daytime Corona Camera also includes a UV events counter which records the number of UV events during a particular time period, thereby determining the intensity of the detected corona.
The Ofil DayCor® Superb-XD Portable Daytime Corona Camera is a practical, efficient, highly sensitive instrument ideal for detecting and recording corona and arcing.
