Filter Reactor
Rated Voltage: Up to 1000 kV
Core Functions:
Configured in series/parallel with capacitor banks to form tuned circuits for:
1.Harmonic Suppression: Attenuates 5th-37th order harmonics (>30 dB reduction)
2.Ripple Control: Limits current fluctuations to ≤1% p-p
3.Resonance Prevention: Detunes grid-capacitor interactions
4.Power Quality Enhancement: Maintains THD<sub>i</sub> ≤3% at PCC
