A case study demonstrates how an effective remote condition monitoring strategy avoids uneconomical operation, costly downtime and consequential damage of wind turbines.
The early detection and fault analysis of bearing problems is crucial. When a rolling-element bearing develops flaws on the races and/or rolling elements, there are four vibration frequencies that can result...
Spectral bands can be a very useful tool for the detection of machine faults. However, not all condition monitoring analysts use them or take advantage of their full potential.
High resistance connections, unbalanced voltages and currents, and a variety of other problems can occur from Power Circuit issues. From the Transformer through the distribution system to the stator connections at the motor, this presentation will perform a deep dive into testing and troubleshooting of the electric motor Power Circuit.
The vibration team suspects a problem with a critical motor at a large pulp and paper facility. Watch this video and learn how the MCEMAX was used to diagnose a significant rotor fault and avoid a $120,000 cost.
Though we never failed to detect actual failures, there were other things going on: overheating, noise, etc. When those issues arose, we were called to the mine to check the equipment. Of course, this would happen at the most inconvenient times...
