Which outcome occurs when high humidity reduces surface resistance of ionic compound insulator supporting high-voltage conductor?

A)Surface arcing across the insulator
B)Bulk breakdown of the insulator volume
C)Electrode corrosion from galvanic coupling
D)Increased capacitance to ground network

💡 Explanation

When humidity increases and reduces surface resistivity across an ionic compound insulator, surface arcing can occur since the moist layer conducts electricity, initiating a discharge across the insulator surface. Therefore surface arcing results, rather than bulk breakdown, corrosion, or capacitance increase which need different conduction mechanisms.
