← TechnologyWhich outcome occurs when a large inductive load energizes near power grid resonance resulting in amplified voltage oscillations?
A)Insulation breakdown from transient overvoltage✓
B)Increased harmonics distorting the current waveform
C)Cascading failure from breaker over-current
D)Reduced eddy current losses in core
💡 Explanation
Insulation breakdown may occur because grid resonance boosts transient overvoltage through the Ferranti effect. This induces large voltage spikes rather than increased harmonics. Therefore, insulation fails; rather than circuit breakers tripping spuriously on sensed overcurrent.
