Which outcome occurs when harmonics circulate in transformer windings?

💡 Explanation

Harmonics causes increased component thermal stress increase because circulating currents induce extra heat via the skin effect phenomenon. Therefore, overheating ensues, rather than other effects, because harmonic frequencies exacerbate losses within the core material.
