The context
Two extraction systems driven by variable speed drives and a production line were analysed at a wood industry plant.
CASE STUDY
Separating harmonics from events
Separate recurring distortion from more severe process-related events to identify where further investigation is needed.
The findings
The measurements distinguish recurring harmonic content from a more severe process-related event.
Technical interpretation
Reviewing recordings alongside load operation helps distinguish different phenomena, avoiding the assumption that variable speed drives alone account for every disturbance.
NEXT STEPS
Distinguishing recurring distortion from process-related events helps focus further investigation and the assessment of mitigation measures.
