Abstract

The amount of variable speed drive (VSD) motors and generators is growing constantly, but VSD use causes partial discharges (PDs) which are the most common reason for the winding damage. Magnet wire manufacturers have developed products that are more resistant against PDs. The objectives of this study were to resolve if the other properties of a corona resistant (CR) magnet wire are sufficient compared to reference wire. Dimension measurement, mandrel, peel, breakdown voltage and pin hole tests were made to both wires.
