Which risk increases substantively when a three-phase power transformer experiences harmonic resonance on secondary winding?

💡 Explanation

When harmonic resonance appears on secondary winding, dramatically increased magnetic fields saturating core occurs because impedance shifts significantly under reactive power imbalances, creating high inrush currents. Therefore transformer saturation results and escalating inrush happens, instead of capacitor, cabling, or breaker failure conditions which require unrelated causes.
