← TechnologyWhich outcome occurs when ground faults bypass main circuit's neutral connection?
A)Elevated voltage stresses occur internally✓
B)Harmonic resonance conditions sharply decline
C)Transformer core saturation greatly diminishes
D)Thermal overload damage reduces noticeably
💡 Explanation
Elevated voltage stresses occur due to ground faults traveling unscheduled lower impedance paths via stray capacitance, because the **zero-sequence impedance** mismatch causes substantial voltage imbalance; therefore leading to transformer core insulation breakdown, rather than alleviating harmonic or thermal stresses via circuit paths.
