Measuring characteristics of magnetic conductors for signal transformers under complex conditions of alternating magnetization

摘要

The paper presents characteristics of cyclic magnetization under ac magnetic fields generated by sine-wave voltages (currents) fed to magnetizing windings of signal transformers with cores from electric steels. These measurements could be performed thanks to the availability of a high-accuracy facility (HAF) at the Ural Research Institute for Metrology, which is designed for measuring magnetic losses. The facility enables digital control of the shape of the magnetizing voltage and digital processing of information.
