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.
