← TechnologyWhich outcome occurs when a surge exceeds MOV rating in power distribution?
A)Overvoltage clamp ceases functioning predictably✓
B)Systematic thermal runaway is exponentially mitigated
C)Precise power factor correction consistently stabilizes
D)Harmonic distortion acutely reduces overall efficiency
💡 Explanation
When a surge exceeds the Metal Oxide Varistor's (MOV) clamping voltage, the device may fail because it cannot dissipate energy quickly enough; therefore overvoltage protection ceases, rather than provide continued protection.
