Daylight corona & partial discharge detection for high-voltage systems
OFIL SYSTEMS
Solar-Blind UV Imaging for Electrical Asset Reliability
About OFIL SYSTEMS
Founded in 1993, OFIL Systems is a global leader in solar-blind ultraviolet (UV) inspection technology for high-voltage electrical assets. OFIL pioneered the use of daytime UV imaging, enabling precise detection of corona and partial discharge activity under full sunlight — a breakthrough that transformed predictive maintenance practices in power networks worldwide.
Over the last three decades, OFIL has expanded its capabilities beyond optical inspection by integrating advanced electro-optical sensors with AI-driven diagnostic tools. This combination allows utilities and asset owners to identify insulation defects, surface discharge, and early-stage failures before they result in outages or catastrophic damage.
Today, OFIL systems are widely used across HV, MV, and LV electrical infrastructure, supporting a proactive, condition-based approach to asset management.
