Good practice guide on the measurement of power losses in non-oriented and grain-oriented steel sheets at frequencies ranging from DC up to 10 kHz using standard measurement setups with variable temperature.

Abstract

Two experimental setups are currently used for the measurement of specific power losses in grain-oriented (GO) and non-oriented (NO) electrical steel – the Epstein frame and the single sheet tester (SST). Measurement of power losses at room temperature using Epstein frame up to 400 Hz is described in IEC 60404-2 [1] and up to 10 kHz in IEC 60404-10 [2]. Measurement of power losses at room temperature using SST is described in IEC 60404-3 [3] with no frequency range stated. The IEC standards give rough guidelines for the measurement of power loss, but allows for individual realizations of the specific setups that all reach the same goal. This is supported by the results of the round robin comparison [4, 5] within the HEFMAG project that agree reasonably well within measurement uncertainties (MUs) for both, SST and Epstein data. This guide also includes details related to measurements from room temperature up to 155°C.
