← ScienceWhich consequence results when high-voltage transmission lines experience corona discharge?
A)Radio frequency interference increases✓
B)Insulator surface flashover decreases
C)Conductor tensile strength improves
D)Electromagnetic shielding effectiveness strengthens
💡 Explanation
Corona discharge ionizes the air creating radio waves. This radio frequency interference increases because ionization generates electromagnetic noise in the surrounding environment; therefore, signal quality degrades rather than other changes in material or insulation.
