Case Histories of current signature analysis to detect faults in induction motor drives
International Electric Machines and Drives Conference, 2003Co-Authors: W T Thomson, M FengerAbstract:This paper will demonstrate through industrial Case Histories how current signature analysis can reliably diagnose rotor cage problems in induction motor drives. Theoretical advancements have now made it possible to predict rotor disturbances due to gearbox dynamics and mechanical drive train characteristics thus making motor current signature analysis (MCSA) testing much more robust and reliable. Case Histories will be presented which demonstrate the ability to separate current components resulting from gearbox dynamics and from those produced by broken rotor bars. From this data, a new handheld instrument for reliable detection of broken rotor bars, air gap eccentricity, shorted turns in LV stator windings, mechanical drive phenomena and certain mechanical problems in induction motor drives is being developed and will be described.

on line current monitoring to diagnose airgap eccentricity in large three phase induction motors industrial Case Histories verify the predictions
IEEE Transactions on Energy Conversion, 1999Co-Authors: W T Thomson, D Rankin, David G DorrellAbstract:An appraisal of on-line monitoring techniques to detect airgap eccentricity in three-phase induction motors is presented. On-line current monitoring is proposed as the most applicable method in the industrial environment and a novel analysis strategy is explained. The practical details of on-site Case Histories and analysis of the current spectra for each motor are presented. The results verify that the interpretation of the current spectrum proposed in this paper was successful in diagnosing airgap eccentricity problems in large, high voltage, three-phase induction motors.

common lessons learned from an analysis of multiple Case Histories
Process Safety Progress, 2011Co-Authors: Xiaole Yang, Linh T T Dinh, Diana Castellanos, Carmen Osorio H Amado, Dedy Ng, Sam M MannanAbstract:In recent years there has been increased emphasis on process safety as a result of major chemical incidents involving gas releases, major explosions, and environmental incidents. Spending some time to fix our eyes on the historical catastrophes of industrial processes is necessary for process safety improvement. While each Case history presents an important foundation for understanding, identifying, and eliminating root causes, to prevent recurrence of these incidents there is a need to identify the common lessons learned. Root causes are usually deficiencies in safety management systems, but can be any factor that would have prevented the incident if that factor had not occurred. In this article, multiple Case Histories were analyzed to understand the common similarities between process incidents. The objective of this article is to focus on learning some common lessons from the historical incidents in order to prevent recurrences of similar incidents. Ten important lessons were identified and are described in this article. © 2011 American Institute of Chemical Engineers Process Saf Prog 2011
