摘要

This paper probes the validity up to 15 kHz of the analytical formulae published in the CIGRE Technical Brochure 908 related to the calculation of the armour losses in single-armoured AC cables, which have been tested in the Brochure at 50 Hz only. After briefly reviewing the theoretical background and carefully explaining the approximations performed by the Brochure, it is shown that for a typical cable, the analytical formulae are reasonably accurate in the estimation of losses up to 15 kHz, but the absolute error increases linearly with frequency.
