| Abstract |
Since a load's failure, like a dip of torque for example, has an effect on the machine supply current ,
then the current spectral analysis approach could be well suited for the study of load anomalies. But
the current signature obtained depends on various phenomena and therefore a misunderstanding of the
results is quite possible.
In this paper an attempt has been made to investigate the monitoring and the diagnostic of a load
connected to an induction motor by the use of the instantaneous power spectrum approach.
The paper presents at first the effect of different load anomalies, in comparison with other machine
anomalies such as broken bar faults. Simulation results are then presented for each kind of load
anomalies.
The relative merits of the instantaneous power spectrum approach can be well appreciated when its
results are compared with those obtained from the current spectrum approach. |
