Which 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.
