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. …
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…
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…
Detection of Loose Connections in VFD with EMPATH
With the motor and pump located elsewhere data was collected from a VFD prior to entering motor or pump information. A loose connection was detected and corrected immediately with post-confirmation.
Connecting the EMPATH Data Collector Special Applications
In this article we will not be covering safety aspects. Safety in connections is based upon corporate rules and regulatory requirements which can change while this article is available. Please ensure that you are working in a safe manner whenever dealing with electrical connections. We will cover some concepts around how connections are made in…
