Which outcome arises when harmonics distort current in a three-phase power transformer?

💡 Explanation

When harmonics distort transformer current, increased high-frequency components induce higher eddy currents in the core because eddy current losses are proportional to the square of the frequency, leading to increased core heating. Therefore, increased core eddy current losses result, rather than insulation cracking, EMI reduction, or improved magnetostriction which operate under different conditions.
