1 Scope This document describes a test method for evaluating the lifetime (3.9) of winding wires under electrical high frequency voltage impulses (with partial discharges) at elevated temperatures. This method is only applicable as a comparative examination under a given sample preparation and testing environment. The comparative nature of this document lies in the fact that the lifetime (3.9) under partial discharges depends on a large number of influencing factors in the sample preparation and test conditions which could not all be thoroughly investigated so far. This document applies to round and rectangular magnet wires.
