Development of an Acoustic Emission Test for the Detection of Anomalies in Hydroelectric Generator Stator Bars and Coils

Authors

Abstract

To meet the ever-increasing demand for electricity, Hydro-
Qu´ebec (HQ) is seeking to simultaneously increase the power
of its generating stations while improving its service quality.
HQ’s research institute (l’institut de recherche d’Hydro-
Qu´ebec - IREQ) has been tasked to investigate innovate methods
to meet the aforementioned goals. Of interest in the
current study, is the development of improved quality control
(QC) to more objectively quantify the results obtained from
the commonly used “Tap Test.” Such methods must detect
anomalies found between the insulation layers of stator bars
and coils as these anomalies can result in partial discharges,
which reduce the service quality of hydroelectric generators.
