Which risk increases in a distribution transformer when subjected to highly reactive inductive loads?

💡 Explanation

When highly inductive loads are present, harmonic currents increase because non-linear loads draw current in short pulses, exciting harmonic frequencies, leading to resonance with transformer winding inductance and capacitance. Therefore harmonic resonance and voltage distortion results, rather than core heating, breakdown, or mechanical fatigue all requiring alternative triggering mechanisms.
