Corona discharges can indicate insulation damage, insufficient clearances or installation faults that may lead to equipment failure. Using advanced UV imaging, OFIL’s DayCor® technology enables accurate detection and location of corona activity on high-voltage assets, helping your maintenance teams identify developing faults before they escalate. Early identification supports safer operations, improves the reliability of your network and allows inspections to be completed in full daylight without interrupting your power supply.

OFIL’s technology helps you detect and locate corona partial discharge on high-voltage equipment, allowing preventative action before faults escalate. Handheld and mounted systems enable inspections on your equipment without interrupting power, minimising operational disruption. View the range.
