Abstract
A method for measuring the specific losses and magnetostriction of grain-oriented electrical steel coils up to six tons is presented. Since transformer core manufacturers are mainly supplied with entire steel coils, a fast incoming goods inspection is desirable. The proposed method identifies the specific losses at certain flux densities of the entire steel coils. In addition, the magnetostriction of the coiled material is measured. With the magnetostriction the main property for transformer no-load noise can be classified. The structure and setup of the developed coil measurement system (CMS) are shown. The measurement technique is explained and its requirements are identified. Initial results of specific power losses and magnetostriction of electrical steel coils as well as the reproducibility of the results are highlighted.
