Which consequence results when dielectric breakdown in transmission lines?

A)Corona discharge power loss increases
B)Impedance matching becomes optimized
C)Skin effect attenuation diminishes
D)Magnetic field interference is shielded

💡 Explanation

Increased corona discharge loss occurs because ionization leads to higher conductivity near the conductor; therefore, dielectric breakdown raises power losses from corona discharge rather than improving impedance because it exacerbates field stress.
