EMPATH Continuous Monitoring Special Applications for Energy Analysis

The EMPATH™ family of Electrical Signature and Motor Current Signature Analysis (ESA/MCSA) systems go well beyond analyzing electric motors, generators and wind turbines.  It provides prognostic and time to failure estimation (TTFE) capabilities for AC/DC electric motors, synchronous machines, servo motors, machine tools, generators – including utility scale, and transformers.  Not only will it identify…

Concepts in Reliability Keeping it Simple and Random Thoughts

As I just mentioned to a friend – I seem to be waxing philosophical this past weekend as I complete reading “Wizard: The Life and Times of Nikola Tesla, Biography of a Genius,” by Marc J Seifer. I would not have tripped over this and several other excellent texts had I not started returning to…

Evaluating Missing Wedges and Coil Movement with ESA IEEE Paper

Two significant issues in wind power asynchronous generators are magnetic wedge loss and coil movement resulting in winding faults.  Most of the time the failures occur unexpectedly or require borescope or visual inspections of the generator stators.  In this paper we will identify how both conditions can be detected during operation through Electrical Signature Analysis. …
