Which outcome occurs when a high-voltage DC transmission line experiences icing, and subsequent increase in the capacitance of insulators?

💡 Explanation

Corona discharge results because the increased capacitance lowers the impedance, enhancing the electric field and causing ionization of air near the insulators due to dielectric breakdown; therefore power loss rises rather than being mitigated without capacitance shift.
