Which risk increases when a distribution transformer operates continuously with impedance value far exceeding design specifications?

💡 Explanation

When impedance greatly exceeds specs, core saturation increases because diminished opposing flux allows the magnetizing current to climb excessively, leading to harmonic distortion in the output voltage. Therefore, core saturation increases resulting in harmonic issues, rather than instability, efficiency, or breakdown each deriving from alternative overvoltage or insulation stresses.
