A shunt reactor is an inductive device used to absorb reactive power, compensating forcapacitance in long transmission lines or cables. By mitigatingthe Ferranti effect (voltage rise at light loads), it stabilizes voltageand improves energy efficiency. They are typically oil-immersed ordry-type, installed directly on the line or a transformer's tertiarywinding.
Key Functions and Benefits
Voltage Stabilization: Absorbs excessive leading reactive power (capacitive) generated by long lines, keeping system voltage within safe operating limits.
Energy Efficiency: Compensates for line capacitance, reducing losses and increasing active power transmission capacity.
Prevent Overvoltages: Protects equipment by mitigating high voltage levels (Ferranti effect) during light-load conditions.
Safety: Minimizes insulation stress on network equipment.
Materials Excellence:
Based on your specific needs, our low-voltage shunt reactors are primarily designed with high-purity copper or high-grade aluminum windings, balancing performance and cost-effectiveness.
Superior Voltage Stability:
We guarantee that the grid voltage remains within the required (+10% to -6%) tolerance range under light load conditions.
Noiseless and Durable:
Utilizing advanced H-class vacuum-impregnated varnish, we reduce operating noise and vibration while protecting internal components.
Space-Saving Design:
Raytech low-voltage shunt reactors feature a compact dry-type core structure, facilitating integration into your existing low-voltage switchgear and compensation cabinets.
Compliant with International Standards:
Products are manufactured and tested according to IEC 60076-6, EN 61558-2-20, and UL 1446 international standards.
