The Ofil DayCor® Uvollé-SX Slender Compact Corona Camera can be used to identify electrical and/or mechanical faults through the detection of partial discharge. It is suitable for performing predictive maintenance on medium and high voltage equipment, making it suitable for use across a variety of industries. For a quick introduction to this product, please see the video below.
Using its UV and visible channels this camera is able to pinpoint corona and arcing. The channels can be overlaid to an accuracy of 1 milliradian. This produces a more comprehensive image allowing the user to pinpoint the exact location of the emitting source. The inclusion of DayCor’s® patented technology also adds to the precision of this instrument, as does its visible zoom, UV magnification and auto and manual focus. DayCor’s® patented technology provides the instrument with greater sensitivity to UV and ensures it is solar blind. Its sensitivity to UV has been tested and certified by an independent laboratory to verify the quality of this camera.
In addition to its image capture capabilities, the Ofil DayCor® Uvollé-SX Slender Compact Corona Camera also includes a UV events counter which can be used to monitor the intensity of the detected corona. The UV events counter functions via recording the number of UV events within a given time period. This function is particularly useful when conducting research, performing comparisons and writing reports.
The ability to save captured images to the removable flash card is also helpful when creating reports. (PLEASE NOTE this instrument can ONLY record images; it has a sister product, the Ofil DayCor® Uvollé-VX Slender Compact Corona Camera, which is capable of recording images, video and audio).These images are viewable via the Ofil DayCor® Uvollé-SX Slender Compact Corona Camera’s 5-inch, reflective, LCD screen with 1000cd/m² sun readable, adjustable backlight. It has a resolution of 800 x 480 pixels ensuring that the images remain sharp and vivid.
The user interface is also accessible via the display. The most frequently used functions are accessible via direct buttons; however, the iconised menu also provides the user with a selection of other functions. Further to this, the operator is able to use the interface to alter default settings in accordance with his/her preferences, for instance, the user can select a preferred corona colour. The Ofil DayCor® Uvollé-SX Slender Compact Corona Camera also includes an interface for GPS, temperature and humidity.
Its backlit display and IP54 rating ensure that the Ofil DayCor® Uvollé-SX Slender Compact Corona Camera can be used in a variety of challenging indoor and outdoor environments, as does its integrated LED torch with two levels of brightness. This torch ensures that the user can continue to use the Ofil DayCor® Uvollé-SX Slender Compact Corona Camera in dark environments without affecting the corona count.
Its battery life of approximately four hours and ability to be used continuously for this period of time without overheating also adds to the convenience and practicality of this product. Its slender, ergonomic, lightweight design means it is easy to handle and may be operated using a single hand; alternatively, it may be carried across and between worksites using a padded shoulder strap.
The Ofil DayCor® Uvollé-SX Slender Compact Corona Camera is a practical, convenient and precise instrument; ideal for identifying and locating electrical or mechanical faults in high and medium voltage equipment via the detection of partial discharge.
