← ScienceWhich risk increases when electrostatic capacitance filters harmonics?
A)Resonance with upstream grid inductance✓
B)Spontaneous dielectric breakdown decreases
C)Overall filter impedance lowers then
D)Harmonic amplification becomes nonexistent here
💡 Explanation
Resonance risk rises because harmonic filters use capacitance; inductive reactance then combines to form resonance at particular frequency which amplifies harmonics, therefore resonance creates instability, rather than harmonic damping at needed filtering rates.
