Which outcome occurs when applying high-frequency AC to underground power cables?

💡 Explanation

Dielectric heating occurs because the alternating electric field polarizes and relaxes the insulation rapidly, resulting in energy dissipation via dielectric losses; therefore the insulation heats, rather than core changes because of transformer specifics, or optimizations of conduction, or connector integrity.
