Summary
This paper presents the experience gained over a period
of several years with Brüel & Kjær Vibro remote condi-
tion monitoring of a large number of Vestas turbines. The
paper describes an efficient implementation of large-scale
remote monitoring of wind turbines using characteristic
scalar measurements combined with automatic tools to
overcome the challenges of the massive amount of data
and alarm information. The importance of transforming the
complex condition monitoring data into actionable informa-
tion, which can easily be integrated into the workflow of
the service organisation, is also addressed. Finally, real-
life examples of detected mechanical faults are presented.
