Atten2 develops oil sensors for condition monitoring in wind turbines. The presentation discusses Atten2's optical sensor technology which can detect various types of fluid degradation and machine wear. This allows early failure detection and root cause analysis. Atten2's sensors integrate with control and monitoring systems and provide remote monitoring services. Case studies show how Atten2's sensors identified issues during repair to avoid future failures. The technology aims to reduce operational risk and costs through optimized maintenance planning.

On-line oil sensors provides valuable and reliable information for the wind
turbine control system and CMS in order to plan O&M activities

24. In the Wind energy industry the average practice is
to change the synthetic oil every 3-5 years.
Using OilHealth is feasible to harness the lubricant life safely, doing a narrow
control of oil parameters in real time.
In synthetic oil the total life cycle is estimated about 7-10 years

25. • A wind turbine manufacturer started to use the
OilWear Sensor in 2015 at their repair shop
located in Spain
• Using OilWear, they identified particles in a
repaired 1,5 MW gearbox.
• The sensor allowed them to identify different kind
of problems in the gearbox:
• Fatigue
• Sliding wear
• External contamination with fiber.
• This early diagnosis avoided a fatal failure in the
gearbox, a major repair and a warranty claim.

WHAT
ATTEN2 ADDING VALUE

28. Emerging Technology Day - 2016 28
Atten2 provides a solution oriented to reduce the operational risk, through the On-line
monitoring of the level of wear that takes place in the machine,
Risk Reduction
Certain kind of inspections such as the bearing, gearbox and shaft, may be accomplished when
the machine condition needs it, instead a calendar base strategy. As added value, the customer
will receive an on-line report about his machine condition and how the operation affects its
reliability.
Productivity
Implementing this Technology may have an impact in cost reduction by:
• Reducing oil changes,
• Reducing important failures in gearboxes and bearings
• Reducing costs in down tower maintenance
• Optimizing maintenance planning and resources
Cost Out
This technology together with operational data, may provide an in-depth information of
the machine condition and may add a new perspective about maintenance policies
