failures. This can be easily performed by analyzing the
signal in the frequency domain and comparing it with the
theoretical frequencies of potential failures.
In this experimental setup, vibration signals are moni-
tored through a data collectio n machine with an Ethernet
connection to a PC. Processing in the frequency domain
is causing a time lag but this is not critical for identifying
a potential progressing fault. The results of the tests show
that the implementation of a vibration monitoring system
on a wind turbine can be helpfu l in identifying and moni-
toring an occurring failure.
