  This paper presents the alternating current (AC) loss analysis on
high-temperature superconductor (HTS) Cross-Conductor (CroCo) cables, in order
to evaluate whether they could be utilized for electrical power transmission.
The modeling of HTS CroCo cables was based on a cable assembled at the
Karlsruhe Institute of Technology (KIT) and the AC loss calculation was based
on the H-formulation model implemented in the finite-element method (FEM)
software package COMSOL Multiphysics. The AC loss calculations have been
carried out for isolated single-phase CroCo cable and three-phase CroCo cables.
The AC loss angular dependence of a particular phase of CroCo cables during
three phase operation has been studied. The current distributions of individual
tapes within CroCo cables have been investigated.
