← ScienceWhich consequence results when a high-voltage transmission line experiences insulator flashover?
A)Ground fault currents get amplified✓
B)Ferranti effect causes gradual failure
C)Corona discharge begins prematurely always
D)Skin effect reduces line impedance only
💡 Explanation
High-voltage insulator flashover creates low-impedance arcs, causing substantial ground fault currents because the breakdown ionizes the air around insulators. This ionisation generates a path for excessive current therefore amplifying the effect rather than corona discharge being limited.
