Oil monitoring gave an early indication of wear in the


At a site near Hull a wind turbine was retro-fitted with FLOW which in addition to accelerometers also monitored oil particulate and condition using Hydac’s MCS1000 measurement and filtration system.


Wear in the gearbox was detected by a higher than normal increase in ferrous particles within the oil. This followed with an increase in gearbox vibration levels approximately 1 week later.

As the wear progressed the rate of deterioration increased as indicated by the particle level. On inspection wear was found on the gear wheels.

Early detection of this wear allowed an up tower replacement of the worn gear wheel resulting in reduced downtime and a possible major failure.
