3-phase line reactor INF 50Hz, 480V, 14% (Cu), INF 14-25-480

Detuning Reactors – Key to Effective Reactive Power Compensation

INF 3-phase detuning reactors with a rated voltage of 480V and a damping factor of 14% are essential components in reactive power compensation systems. Their task is to limit the flow of harmonic currents and ensure stable operation of the electrical installation. They are used both in new installations and in modernized industrial and energy facilities.

Construction and Application

INF reactors are characterized by a solid construction based on a copper (Cu) winding and vacuum impregnation in class H varnish, which ensures high durability and resistance to environmental conditions. They are designed for continuous operation (100% duty cycle) in natural cooling conditions (AN). Their main application is the reduction of harmonics generated by non-linear loads, such as frequency converters, switch-mode power supplies, and compact fluorescent lamps. This improves energy quality, reduces network losses, and extends the life of equipment.

Advantages and Benefits

• Harmonic Limitation: Reactors effectively suppress harmonics, protecting sensitive equipment from damage and interference.
• Power Factor Improvement: They reduce reactive power consumption, which translates into lower electricity bills.
• Increased Reliability: They stabilize the operation of the electrical installation, minimizing the risk of failure.
• Durable Construction: Made of high-quality materials (copper, class H varnish) guarantees long life and trouble-free operation.
• Safety: Equipped with a thermal overload protection switch, providing additional protection against overload.
• Compliance with Standards: Meet the requirements of EN/IEC 61558-2-20 and EN/IEC 60076-6 standards, confirming their safety and quality.

Technical Parameters – What You Should Know

INF 14-25-480 reactor is characterized by a rated power of 25 kVar at a voltage of 480V and a frequency of 50Hz. The inductance of this model is approximately 4.11 mH. It is worth paying attention to the damping factor of 14% (at a resonant frequency of 134Hz), which indicates the effectiveness of the reactor in limiting harmonics. The weight of the device is approximately 17.5 kg and the dimensions are: L=240mm, H=190mm, B=106mm and d=84mm with a mounting hole e=10x18mm. The reactor is designed for mounting with angle brackets. Insulation class F(155°C) allows operation at ambient temperatures up to 40°C.
