Evaluation of Asynchronous Wind Generator Stator Magnetic Slot Wedge and Coil Movement Using Electrical Signature Analysis
Abstract— 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…

ECMS-1 NEW
The ECMS-1 is the single-channel version of the EmpathCMS system. All of the capabilities, same software, same function and designed for supporting single wind turbines, motors, generators or transformers. Allows you to mix and match EmpathCMS and ECMS-1 in the system to monitor and identify defects from one machine to 3200 machines per software instance.…
Case Study Wind Generator Drive End Bearing Defect
Tested with the EMPATH® system from the base of the tower on a GE 1.xx ESS, bearing defects were found in the drive end bearing with the automated analysis. In this case study, we will show the voltage and current signatures, but not included are the kilo-Watt and torsional spectra used to determine severity. Following…
Energy and Environment Impact from Machine Defects with EMPATH ESA
Electrical and Mechanical Defects in an electrically driven machine have a direct impact on energy consumption. This can be from sub-standard maintenance practices, such as misalignment or belt tension, or degrading components such as bearings, belts, impellors, gears, and other parts. In this article we will discuss a simple motor/pump combination on a Variable Frequency…
