← ScienceWhich consequence occurs when a powerful electromagnetic pulse encounters unshielded long-distance power transmission lines?
A)Transmission synchronicity is temporarily disrupted
B)Arcing damages insulators between line✓
C)Increased corona discharge occurs at conductors
D)Ferroresonance oscillations destabilize voltage
💡 Explanation
Arcing occurs, because the electromagnetic pulse induces very high voltages through electromagnetic induction. This voltage surge then exceeds the dielectric breakdown strength of the insulators, therefore arcing occurs, rather than gradual synchronization issues or corona discharge enhancements.
