Function Description
Primary Functions
● Dynamic Power Factor Correction: Maintains target PF (typically 0.95-1.0)
● Voltage Regulation: Stabilizes bus voltage within ±2%,Mitigates voltage fluctuations, especially for long-distance transmission or impact loads (e.g., rolling mills, arc furnaces).
● Harmonic Mitigation: Optional filter reactors (5%, 7%, 12% reactance rate) to mitigate harmonics (THD <5%).
● Energy Optimization: Reduces system losses by 5-15%
Control Functions
● Automatic capacitor bank switching
● Load balancing between phases
● Fault detection and diagnostics
● Data logging and event recording
● Intelligent Control – Built-in PLC/DSP controller with remote monitoring (RS485/Ethernet/4G).
Selection guide
| Load Type | Recommended Solution |
|---|---|
| Steady Loads | Fixed compensation (contactor switching) + automatic grouping |
| Fluctuating Loads | Thyristor-based dynamic compensation (TSC) or hybrid SVG |
| High-Harmonic Environments | Capacitors + detuned reactors (filter design) |
