Ofil Railway Corona Inspection System with DayCor

Ofil recognized that rail systems needed a way to detect corona and arcing partial discharges as tolerance for electrical faults has decreased. DayCor® Rail is a system designed to identify corona discharges and existing failure processes so they can be traced and eliminated.

Using patented DayCor® technology, DayCor® Rail offers both outstanding sensitivity to Ultraviolet (UV) signals and the ability to capture existing signals, their emissions and emitting objects at high speeds. Results are recorded, stored and displayed in reports in HD video with appended details including GPS locations, ambient conditions and the count of total corona events.

SUPERIOR CORONA DETECTION

DayCor® Rail has a sensitivity to UV of 1pC at least from a distance of 10 meters and 7.7dBμV (RIV) @ 1MHz which allows it to detect distant corona discharges. DayCor® Rail's fast processing camera means rail can be moving at speeds up to 300 km/h without degradation of performance. Recorded images reveal corona flecks from their emitting objects without smears or blurring.

AUTOMATED OPERATION

DayCor® Rail is an autonomous standalone system that you turn on before departure and turn off upon arriving at the final destination.  There is no requirement to work with the device while in transit.

RUGGED AND STABILE

DayCor® Rail has been designed to withstand harsh environments and has a high tolerance for vibrations and bumpy rides, allowing smooth video recordings without interruptions.

DAYCOR® TECHNOLOGY INSIDE

Ofil’s DayCor® technology is solar blind and accurately overlays both UV-Visible channels with highly accurate detection.

RECORDING OF CORONA

During a trip, the DayCor® Rail will record and store video of discovered corona. The unit captures and stores video and metadata of problem areas that require further investigation.

CUSTOMIZABLE

DayCor® Rail can fit into any rail environment and can be customized to meet specific architectures, platforms, languages and other preferences. Simply speak to your Berg representative regarding your specific needs and requirements.

DATA PROCESSING

All detected corona events are processed through Ofil's CoronaCatch application. CoronaCatch separates corona events from non-corona events and attaches GPS, ambient conditions and corona severity measurements.

AUTOMATIC REPORTING

CoronaCatch automatically generates reports from your captured data that are compatible with Ofil’s Corona-Base Reporting Software. [Registered Patent EP1112459B1]
