摘要
Two methods are compared. These are: determination by means of field-sensing coils, determination and from the magnetizing current. The errors of both methods were calculated by the finite-element method when different paramenters were varied. SSTs with wound and stacked yokes were considered. The results will help in deciding whether the more complicated and more accurate H coil method or the easier-to-handle, but less accurate, magnetizing current method should be used.
