✦ Synopsis
The measured self-field a.c. losses in mono-and multi-filamentary tapes with varying transport current, frequency and voltage tap configurations are compared to theoretical models. The observed losses are found to approach asymptotic values when the loop of the voltage taps is comparable to the width of the tapes. The measured quadrature electric field is found to be nonlinear with applied current. A model is presented to describe this nonlinearity for homogeneous elliptical and strip geometries. The possible significance of the model to the observed losses is also discussed.
