Which outcome occurs when ferroresonance stresses insulation within a transformer?

💡 Explanation

Ferroresonance induces high transient voltages because oscillatory energy exchange exceeds insulating capacity, leading to dielectric breakdown; therefore, insulation rapidly fails, rather than eddy current reduction or harmonic control which need dedicated hardware.
