Which outcome results in a three-phase power distribution transformer when hysteresis losses increase excessively due to elevated operating temperatures?

💡 Explanation

Elevated temperatures increase the magnetic domain wall motion because this escalates the **hysteresis mechanism**, leading to higher core losses. Therefore efficiency decreases rather than improving; insulation breakdown rises independent of core losses.
