← ScienceWhich failure occurs when a high voltage DC transmission line charges an underground cable's capacitance?
A)Dielectric breakdown across cable insulation✓
B)Increased skin effect within the conductor
C)Corona discharge around support structures
D)Ferranti effect inducing voltage drops
💡 Explanation
Dielectric breakdown can occur because charging the cable capacitance causes a high electric field stress across the insulator exceeding its breakdown strength. This results in insulation failure, rather than skin effect or corona which relate AC-specific phenomenon.
