Which risk increases when transmission lines experience icing?

A)Corona discharge field intensification
B)Ohmic heating reduction greatly
C)Capacitive reactance diminishes rapidly
D)Dielectric breakdown increases markedly

💡 Explanation

Intensification of the electric field occurs at ice points because charge concentrates, leading to increased ionization via Corona discharge. Because the ice causes pointed regions, therefore the electric field increases rather than the other electrical parameters. Furthermore capacitance would decrease with volume.
