← ScienceWhich consequence results when a high-impedance fault disrupts power transmission?
A)Cascading voltage collapse occurs system-wide✓
B)Ferranti effect raises receiving voltage
C)Skin effect increases line resistance
D)Mutual inductance perfectly balances loads
💡 Explanation
A high-impedance fault causes widespread voltage drops because voltage sag initiates **cascading failure**, compromising reactive power supply; therefore a collapse occurs rather than localized voltage changes or inductive load balancing modifications.
