✦ Synopsis

Theoretical studies are presentea for transient field losses in multifilamentary composite conductors carrying a dc transport current. The analysis of the total loss is split into separate calculations of the magnetization loss and the loss due to the dynamic resistance. Analytical expressions are derived for a field change of trapezoidal shape. The parameter which characterizes the total loss is a dimensionless sweep rate of the external field = T[}e/a p, where T is the relaxation time of the eddy current and Bp is the fullpenetration field of the composite conductor. Graphs for a wide range of the field change rate are given and they reveal the strong influence of the transport current.
