Multiple Detuning Options: Choose from 7%, 14%, or 27% reactance rates to target specific harmonic orders. The 7% option suppresses 5th order and above, while 14% handles 3rd order harmonics effectively.
Robust Construction: Non-magnetic fasteners and vacuum impregnation create a solid bond between core and windings. This process ensures low losses and maximum harmonic suppression capability.
Compact Design: Our space-efficient design fits standard electrical cabinets while maintaining excellent thermal characteristics. You save installation costs and reduce footprint requirements.
Practical Applications
Industrial Manufacturing: Your VFD-intensive operations benefit from reduced harmonic interference and improved motor performance. The Series Low Voltage Reactor prevents resonance between drives and capacitor banks.
Data Centers: Critical IT infrastructure requires stable power quality. Our reactors protect UPS systems and prevent harmonic amplification from switching power supplies and server loads.
Commercial Buildings: Modern facilities with extensive LED lighting and HVAC systems generate significant harmonics. You achieve compliance with power quality standards while protecting sensitive equipment.
Renewable Energy Systems: Solar and wind installations create complex harmonic patterns. Our reactors stabilize inverter outputs and prevent grid interaction issues.
How It Works
Your Series Low Voltage Reactor functions by altering the natural resonance frequency of the capacitor-reactor circuit. When connected in series with capacitors, it shifts the tuning frequency below dominant grid harmonics.
The inductive reactance increases with frequency, creating a high-impedance path for harmonic currents. This prevents harmonics from flowing into capacitors while allowing fundamental frequency power to pass freely.
During switching events, the reactor limits inrush currents through controlled impedance. This protection extends capacitor life and prevents contactor welding in automatic power factor correction systems.

FAQ
Q: How do I select the correct detuning percentage for my application?
A: The choice depends on your dominant harmonic content. Use 7% for standard industrial loads with VFDs, 14% for high single-phase harmonic environments, and 27% for specialized applications requiring broad-spectrum suppression.
Q: Will adding a reactor affect my capacitor bank's kvar output?
A: Yes, the reactor slightly reduces reactive power output. You may need to resize the capacitor bank to maintain desired power factor correction levels.
Q: Can your reactors handle high ambient temperatures?
A: Our Class H insulation system operates reliably up to 180°C. With proper ventilation, the units perform excellently in ambient temperatures up to 50°C.
Q: What maintenance is required for your Series Low Voltage Reactor units?
A: Minimal maintenance is needed. Annual visual inspections and thermal imaging help identify potential issues early. The robust construction provides years of trouble-free operation.
