Measurement of Magnetic Properties of Grain-Oriented Electrical Steel Sheet Using 2D Single Sheet Tester

摘要

Oceniono dokładność badania blachy zorientowanej przy wykorzystaniu testera 2D SST. W celu oceny niepewności wyniki porównano z rezultatami otrzymanymi przy wykorzystaniu konwencjonalnego testera SST. Przedyskutowano problem błędu pozycjonowania czujników.%We have already reported the accuracy of measurement of 2D magnetic properties of non-oriented electrical steel sheet using a novel SST. In this paper, magnetic properties under alternating and rotating magnetic flux of grain-oriented sheet are measured. The accuracy of measurement in the case of grain-oriented sheet is examined by comparing the measured results using 2D-SST with those using an ordinary SST under alternating flux excitation. The effect of positioning error of orthogonal B and H coils on measurement accuracy is also discussed.
