To calculate the radial current distribution and core loss within a concentric-lay steel-cored conductor, the magnetic properties of the core must be known for any service condition. The paper describes comprehensive measurements on a length of the steel core taken from a 54/3.77 mm + 19/2.24 mm (Grackle) ACSR conductor. Curves are given to illustrate the effects of magnetic field strength, tensile stress and temperature on the modulus, real and imaginary parts of the complex relative permeability, the hysteretic angle, the loss tangent, the total core loss and the hysteresis loss.
