Stators, Transformers, Inductors: Solving Issues of Testing for Safety and Quality

Safety and quality testing for defects or even potential defects in component windings like a layer short, corona or partial discharge, or flashover is critical in early phases of design and throughout production. Until now, makers of wound components like motor stators, transformers, and inductors required several instruments and multiple test stations active in order to comply with EC/UL standards.

This seminar will cover some of the standards related to these components, test equipment, and test methods to comply with those safety and quality standards. We will also introduce a new solution that performs multiple tests in one instrument; saving resources and increasing throughput. Tests include Impulse winding, hipot and flashover detection, insulation resistance, and DCR measurements.
