← TechnologyWhich outcome occurs when a solid-state circuit breaker in a high-voltage DC transmission line activates?
A)Suppression of transient over-voltage surges✓
B)Increased harmonics in the DC waveform
C)Elevated reactive power compensation needs
D)Greater electromagnetic field interference production
💡 Explanation
Activation enables transient voltage suppression because the solid-state breaker utilizes fast-switching semiconductors to clamp the voltage. This clamping absorbs excess energy, leading to transient suppression, therefore surges are mitigated rather than harmonics/EMF increases, preventing DC line flashovers.
