Reliable predictive maintenance must consist of trustworthy inspection tools, precise data, numbers that can be processed into reports and a solid methodology as a backbone.

Predictive maintenance has already been proven as cost effective to utilities, provided it is routinely done by a taskforce that can foresee the invisible. Corona discharge is an invisible (during daytime) agent that if detected can provide information about sources of failures, failures in process, and even assist avoiding unscheduled shutdown.

Corona is an electrical field related phenomenon, invisible during daytime, detected by DayCor® and UVollé bi-spectral UV-Visible cameras. Ofil composed a methodology to support users of corona cameras (read more...). The purpose of this methodology is to eventually provide a decision aiding tool.

 

Ofil’s methodology is graphically displayed as a decision chart and printed on a card with a retractable cord (get a copy...). DayCor® users use the decision aiding chart when doing inspections.

Ofil's decision aiding chart is reinforced with a dedicated database and report generating software. Long hours of inspection are thus stored in a database with easy access to each item, and summarized in versatile reports that help manage and maintain reliable electrical systems, as expected.
