The Ofil DayCor® Uvollé-VC Compact Corona Camera includes audio and video recording capabilities in addition to all the features and functions found on the Ofil Daycor® Uvollé-SC Compact Corona Camera. Like the Oil DayCor® Uvollé-SC Compact Corona Camera, the Ofil DayCor® Uvollé-VC can be used to locate and identify mechanical and electrical faults via detecting partial discharge. It is suitable for performing routine maintenance checks on high and medium voltage equipment such as:
This versatility of application makes it a suitable for use across the following industry sectors:
The Ofil DayCor® Uvollé-VC Compact Corona Camera can be used continuously without overheating and includes a battery that provides power for upwards of four hours. It is an efficient, compact and ergonomic instrument that may be operated using a single hand and features a simple yet intuitive interface. The user may use this interface to adjust the default operation settings to suit his/her preferences. The Ofil DayCor® Uvollé-VC also includes an interface for GPS, temperature and humidity.
The interface is viewable on the Ofil DayCor® Uvollé-VC's 4.3-inch, reflective, LCD screen with a 600 nits backlight. The design of this display ensures that the user is able to view the content in all light conditions. Images and videos taken using the Ofil DayCor® Uvollé-VC Compact Corona Camera can be viewed in vivid colour and sharp definition on this display. They can also be saved, with audio notes, to the removable flash card for consultation/ playback at a later time.
The ability to record and playback videos and images with audio notes is particularly helpful for users wishing to create reports. Another feature present on the Ofil DayCor® Uvollé-VC Compact Corona Camera which is well-suited to creating reports is the UV events counter which indicates the intensity of detected corona numerically. This feature counts the number of UV events within a given time period to determine corona intensity.
This feature, combined with the Ofil DayCor® Uvollé-VC Compact Corona Camera’s UV and visible channels, facilitates the clear and precise detection and location of corona and arcing. It includes patented DayCor® technology which provides complete solar-blindness and increased sensitivity to UV. The UV and visible channels can be overlaid to an accuracy of 1 milliradian, allowing for greater clarity and therefore more precision in pinpointing the emitting source. Clarity and precision are further improved with the inclusion of a visible zoom and UV magnification, as well as an auto and manual focus. Moreover, the camera present on this model has been independently verified in order to ensure that it is of a suitable quality.
The Ofil DayCor® Uvollé-VC Compact Corona Camera can be used to detect corona and arcing in a multitude of environments due to its dust and water resistant design (IP54) and the inclusion of a built-in LED torch with two brightness settings. This torch makes it possible for the user to work in the dark without affecting the corona count. Finally, this instrument can be easily carried across or between worksites using a padded shoulder strap.
The Ofil DayCor® Uvollé-VC Compact Corona Camera is ideal for quickly, comprehensively and accurately identifying partial discharge in order to locate and determine electrical and/or mechanical faults.
