Which risk increases from exceeding the Curie temperature constant within a transformer core?

💡 Explanation

When the Curie temperature is exceeded, the ferromagnetic properties of the transformer core material are lost because thermal energy disrupts the magnetic domain alignment, leading to increased hysteresis losses and reduced efficiency. Therefore, increased energy losses result, rather than dielectric breakdown, short circuits, or mechanical failure, which involve other mechanisms.
