On the Eddy Current Losses in Metallic Towers [PDF]
International Journal of Renewable Energy Development, 2020 The existence of magnetic field around high-voltage overhead transmission lines or low-voltage distribution lines is a known fact and well-studied in the literature. However, the interaction of this magnetic field either with transmission or distribution
