Partial Discharge Course October 28-30, 2025 – Iris Power, Toronto, Canada

About The Course

The objective of this Partial Discharge Seminar is to understand basic PD theory as well as stator winding insulation systems and why they deteriorate. To learn how PD detection devices work and interpret the test data collected and relate the data to specific failure mechanisms, to enable you to plan stator winding maintenance.

The course is designed for engineering and maintenance personnel who either purchase, install, test, maintain and/or repair motors and/or generators. Consultants, manufacturers and repair shop personnel would also benefit from this course. The course is mainly intended for those involved with motors or generators rated 3kV and above.

Topics covered in this course include:

Motor & Generator Stator Windings

• Stator Winding Design
• Coil Manufacturing Process
• Failure Mechanisms

PD Theory

• PD as a Symptom

Instructor:

Dr. Greg Stone was one of the developers of on-line partial discharge test methods to evaluate the condition of the high voltage insulation in stator windings.  From 1975 to 1990 he was a Dielectrics Engineer with Ontario Hydro, a large Canadian power generation company.  Since 1990, Dr. Stone has been employed at Iris Power L.P. in Toronto Canada, a motor and generator condition monitoring company he helped to form.  He has published two books and >200 papers concerned with rotating machine windings.  He has awards from the IEEE, Cigre and IEC for his technical contributions to rotating machine assessment.  Greg Stone has a BASc, MASc and PhD in Electrical Engineering from the University of Waterloo (Canada), is a Fellow of the IEEE.  He is a registered professional engineer in the Province of Ontario, Canada.
