DayCor® Rail is a fully automatic stand alone corona inspection systems dedicated to railway. Rail incorporates the DayCor® daytime corona detection and reporting system in a ruggedized structure. It is designed for high speed automatic detection of corona & arcing, capture of videos and images, and on-the-fly reporting. Detected corona events are recorded and processed automatically by Ofil′s CoronaCatch application, that segregates corona events from non corona events and attaches to each event its specific meta information, including: GPS, ambient conditions and severity. Ofil′s CoronaCatch uses the processed information to generate reports that are compatible with Ofil′s Corona-Base Reporting Software.
