适用范围：Nowadays, by computer aided testing (CAT), a.c. magnetic properties of electrical steelsheets can be measured under various measuring conditions automatically. For example, themagnetic loss in the presence of higher harmonic frequency components of magneticpolarization can be measured using the arbitrary waveform synthesizer, digitiser andcomputer.The present standard methods (IEC 60404-2, IEC 60404-3 and IEC 60404-10) for thedetermination of specific total loss are restricted to the sinusoidal waveform of magneticpolarization, and these standards are still important for the characterization of core materials.However, actual waveforms of magnetic polarization in the electrical machines andtransformers always include higher harmonic polarizations, and nowadays electrical machinescan be designed using numerical methods including higher harmonics. But for theseconditions, there is still no standard testing method.This technical report reviews methods for measurement of the magnetic loss of soft magneticmaterials under the condition of magnetic polarization which includes higher harmoniccomponents.
