The gearbox oil and the wind turbine gearbox condition are correlated. The oil can give the wind turbine operator the necessary information to plan maintenance and avoid costly repairs. Therefore, a test bench that can reproduce the gearbox operating conditions would be necessary to test oil-sensors. This paper presents a first testing approach using a Highly Accelerated Life Test / Highly Accelerated Stress Screening test chamber. It allows assessing the performance of oil properties sensors under extreme ambient temperature and vibration levels, based on measurements from a wind turbine gearbox. Results from a test on an oil properties sensor are presented and discussed.
