SUMMARY The insulation system in form-wound stator windings is exposed to electrical, mechanical and thermal stresses, in addition to factors such as humidity ...
INTRODUCTION Partial discharge (PD) measurement is widely used for all types of high voltage equipment for both factory quality assurance and insulation system ...
