Which consequence results when eddy currents form excessively in power transformers?

A)Core lamination overheating increases
B)Increased output voltage instability occurs
C)Enhanced magnetic field confinement results
D)Winding insulation layer strengthening occurs

💡 Explanation

Excessive eddy currents induce heat because they are circulating currents within the transformer core material; therefore, core lamination overheating increases, rather than enhancing field confinement as decreased current density and associated ohmic losses happen under normal conditions.
