← ScienceWhich risk profoundly increases when a high-voltage transformer's inductive reactance improperly cancels capacitive reactance?
A)Resonant frequency inrush currents appear✓
B)Eddy current losses greatly decrease
C)Hysteresis losses become negligible
D)Transformer core saturation is prevented
💡 Explanation
A resonant frequency emerges on the capacitance and inductance are balanced, because it lowers impedance; therefore large inrush currents appears, rather than eddy current reduction or prevention of transformer core saturation, as imbalances worsen those.
