We have developed a calculation method for the strand current distributions in the turbine generator armature windings. These distributions are calculated by using a circuit equation and a 3D finite element method. In the circuit equation, the strand current is solved by introducing a circulating current at each strand of the armature windings. The induced voltage in the circuit equation is produced by leakage flux of the coil end region. The leakage flux is obtained by the 3D finite element method. The calculated strand current distributions had good agreement with the measurements of 360-degree, 450-degree and 540-degree transposed model coils.
