The Ofil DayCor® Uvollé-VX Slender Compact Corona Camera is the sister product to the Ofil DayCor® Uvollé-SX Slender Compact Corona Camera and as such features all the same features and capabilities as the Uvollé-SX but with the addition of video and audio capture functions.
Like its sister product, the Ofil DayCor® Uvollé-VX can be used to identify electrical and/or mechanical faults in high or medium voltage equipment via the detection of partial discharge. For a quick introduction to this product, please see the video below.
The Ofil DayCor® Uvollé-VX Slender Compact Corona Camera features a slender, handheld, bi-spectral design. The inclusion of patented DayCor® technology means that it is solar blind and highly sensitive to UV. This camera’s UV sensitivity has been independently tested and certified in order to verify the quality and accuracy of the instrument.
Further to this, the Ofil DayCor® Uvollé-VX Slender Compact Corona Camera can overlay its two channels, UV and visible, to an accuracy of 1 milliradian, making the detection and location or arcing and corona simpler and more precise. The inclusion of visible zoom, UV magnification and auto and manual focus also adds to the ease of corona detection.
Images and videos captured using the Ofil DayCor® Uvollé-VX Slender Compact Corona Camera can be viewed on its 5-inch, reflective, LCD screen with 1000cd/m² sun readable, adjustable backlight. As this display has a resolution of 800 x 480 pixels it is able to provide the user with clear, sharp, vivid images and footage. Media captured using this camera can also be saved, with audio notes, to its removable flash card for consultation and/or playback at a later date. This function is particularly useful for those writing reports.
Indeed writing reports, conducting research and/or performing comparisons become easier still due to the inclusion of a UV events counter which allows the user to monitor the intensity of the detected corona. This feature works by recording the number of UV events that take place over a given time period.
In addition to its extensive image capture, corona detection and recording capabilities, the Ofil DayCor® Uvollé-VX Slender Compact Corona Camera has also been designed to be as practical and covenant as possible. To this end, it has been optimised for both indoor and outdoor use and features a lightweight, water and dust resistant design (IP54) and an integrated torch. This built-in LED torch has two brightness levels and ensures the camera can be used in visually challenging environments without affecting the corona/ UV events count.
With regards to its convenience, the Ofil DayCor® Uvollé-VX Slender Compact Corona Camera may be used continuously for approximately four hours without overheating, whilst its slender design and simple interface ensures that it can be operated using a single hand. The Ofil DayCor® Uvollé-VX Slender Compact Corona Camera provides easy access to commonly used features via function buttons; however, the user is also able to access an array of additional features via the camera’s interface. This interface can also be used to adjust default settings in accordance with the user’s preferences, e.g. the user can select a colour to indicate corona. The Ofil DayCor® Uvollé-VX Slender Compact Corona Camera also facilitates GPS, temperature and humidity interfaces.
Finally, the Ofil DayCor® Uvollé-VX Slender Compact Corona Camera can be carried across and between worksites using a padded shoulder strap.
The Ofil DayCor® Uvollé-VX Slender Compact Corona Camera is the ideal instrument for finding and capturing evidence of electrical and/or mechanical faults in high and medium voltage equipment via the detection of partial discharge.
