Hidden Defect found in a VFD with Vibration Analysis

Hello Everyone,

Here is the third of the five case studies brought to you with the Reliability Training Institute. In this case study we show how vibration analysis detected a hidden failure in a variable frequency drive. Hopefully, you are finding them of use and helpful.

These case studies are to support my book ‘Enhanced System Reliability Through Vibration Technology’ and my role as an RMS Trainer with the RMS Reliability Training Institute.

Many thanks to Dr Jezdimir Knezevic from MIRCE Science for his enlightening discussion (and MIRCE Science) and to Dean and Stuart at RMS for all their support.

This case study and more can be viewed on the RMS Blog.
