← TechnologyWhich outcome occurs when rapid current variations exceed switchgear breaker's ratings?
A)Critical arcing creates plasma channel✓
B)Increased dielectric withstand capability occurs
C)Improved surge protection circuit forms
D)Enhanced magnetic field strength develops
💡 Explanation
Massive overcurrents drive *thermal ionization*, because exceeding the switchgear breaker rating triggers an unrestrained increase in temperature and ionization within the contact gap, therefore allowing highly conductive plasma arc escalation to occur, rather than controlled voltage suppression.
