Which outcome occurs when a high-voltage DC transmission line develops a ground fault with limited fault current?

💡 Explanation

When a ground fault occurs in a HVDC system with limited fault current, electrolytic corrosion occurs because the DC current flows to ground through buried metallic structures, causing electrochemical reactions. Therefore corrosion results, rather than over-voltage, breaker trips, or harmonic distortion, which require high fault currents or inductive coupling effects.
