Abstract :
A nonenwrapping, single yoke, online magnetic testing system for measuring the magnetic properties of electrical steels in the steel industry has been developed. The magnetizing conditions within the arrangement have been investigated. Various methods of conveniently measuring the secondary voltages have also been studied. Various types of noncontact search coils for measuring flux density have been investigated. It is shown that a nonsolid search coil can be used as a secondary coil. Losses measured with the system agreed to within ±5% of the results obtained using an Epstein frame
