Working Steps of CKFG-1.2/0.25-6% Series Low Voltage Series Reactor
Harmonic suppression and resonance avoidance
Step 1: Harmonic Filtering
When a reactor is connected in series with a capacitor, it forms an LC circuit tuned to a specific harmonic frequency (for example, 6% reactance for the 5th and 7th harmonics, and 7% reactance for the 5th to 7th harmonics). This configuration diverts harmonic currents away from sensitive equipment, preventing resonance and harmonic amplification.
Step 2: Voltage Stabilization
By absorbing harmonic voltages generated by non-linear loads (e.g. inverters, rectifiers), reactors mitigate voltage distortion, ensuring cleaner waveforms for downstream equipment.
Reactive power optimization
Step 3: Capacitor Protection
The reactor limits the inrush current during capacitor switching (up to 1.35 times the rated current), protecting the capacitors from thermal stress and extending their service life. It also balances the voltage distribution between capacitor banks, enhancing system stability.
Step 4: Power Factor Correction
By compensating for inductive reactive power, the reactor improves the power factor to ≥0.95, thereby reducing energy losses and optimizing transformer capacity.
Sturdy aluminum wire design
Step 5: Efficient heat dissipation
7% aluminum wire windings are lightweight, durable, and optimized for thermal management. Combined with H-class insulation and dry cores, they ensure low noise (<50 dB) and reliable operation in harsh environments (-25°C to +45°C).
Step 6: Long life and low maintenance
The core is made of high-quality silicon steel sheets and adopts a distributed air gap design to minimize eddy current losses and magnetic saturation. The vacuum impregnation epoxy coating further enhances the moisture and vibration resistance of the core.

1. Advanced harmonic suppression and reactive power compensation
The CKFG-1.2/0.25-6% series low voltage series reactor is designed to suppress 5th and 7th harmonic distortion while optimizing reactive power flow in low voltage grids. With a reactance ratio of 7%, it can form a resonant circuit with capacitors to absorb harmonics, thereby improving the power factor by up to 95% and reducing energy losses. This makes it an ideal choice for non-linear load industries (e.g. data centers, manufacturing industries), ensuring compliance with IEEE 519 harmonic limit standards.
2. High efficiency aluminum wire structure
This three-phase reactor uses 7% aluminum wire winding, which has superior conductivity and thermal performance compared to copper wire. The lightweight design reduces installation costs while maintaining low iron loss (<0.5W/kg) and temperature rise (<95K). H-grade epoxy resin impregnation ensures moisture resistance and noise reduction (<50dB), making it suitable for harsh industrial environments.
3. Grid stability and three-phase balance
Designed to solve voltage fluctuation and phase imbalance problems, the reactor stabilizes grid performance by limiting surge current (≤1.35 times rated current) when capacitors are switched. Its core is made of cold-rolled silicon steel, ensuring linear reactance even under overload conditions (1.8 times rated current), thereby preventing harmonic resonance and equipment damage.
4. Low maintenance and reliability
Dry construction eliminates the risk of oil leaks, provides extremely low maintenance and a service life of more than 20 years. An integrated thermal switch prevents overheating, and the vacuum impregnated coil core assembly ensures high dielectric strength (3kV/min). This durability reduces downtime, making it a cost-effective choice for mission-critical applications.
5. Multiple applications in power quality systems
The reactor is compatible with 230–660V systems and performs well in active power factor correction (APFC) panels, harmonic filter banks, and capacitor compensation systems. It integrates seamlessly with smart grid technologies to enhance voltage regulation and mitigate harmonic pollution, supporting renewable energy integration and energy-saving operations.
Wiring Method of CKFG-1.2/0.25-6% Series Low Voltage Series Reactor
1.Coil Wiring: The coil terminal of the reactor should be correctly connected to the system according to its requirements. Generally, the reactor has three terminals, namely A, B, and C. In low-voltage systems, the A, B, and C terminals of the coil can be connected to their respective system phase lines, that is A phase, B phase, and C phase. In the case of high-voltage systems, it is required to connect the coil of the reactor as per the three-phase wiring arrangement (for example, star or delta wiring) of the system.
2.Grounding: The grounding of the reactor is significantly important because it is associated with the safety and stability of the system. Under normal conditions, the neutral point (if exists) of the reactor needs to be grounded. In addition, grounding connection must be noted for the following two points:
3.Use Proper Grounding Resistance: Generally, grounding resistance is used at the grounding point of the reactor to limit the flow of ground fault current. Grounding resistance value must be chosen by the systems' requirements and standards, ensuring that ground current remains within a controllable limit.
4.Ground Current Monitoring: To provide early detection of ground fault, a ground current monitoring device can be connected to the grounding point of the reactor that monitors the ground current in real-time and triggers alarm or protective measures when it goes beyond the threshold set.
In conclusion, connecting the wiring properly and grounding rightly is a step toward ensuring the proper operation of a reactor. Connect the coil terminals as per the system demands and provide appropriate grounding measures to ensure safety and stability in the system.

Applications of CKFG-1.2/0.25-6% Series Low Voltage Series Reactor
Commercial buildings and data centers
Commercial complexes, office buildings, and data centers face unique power quality challenges because various loads (LED lighting, HVAC systems, and IT infrastructure) generate harmonics and reactive power imbalances. The CKFG-1.2/0.25-6% series addresses these issues by filtering the 3rd, 5th, and 7th harmonics emitted by non-linear loads (such as variable speed drives in elevators and UPS systems in data centers). By attenuating harmonic currents, the reactors protect transformers and switchboards from overheating and premature aging, extending equipment life by up to 30%.In terms of reactive power optimization, the reactor works in conjunction with the capacitor bank to maintain a high power factor (≥0.92), reduce energy waste and lower electricity bills. For example, in a large shopping mall, the CKFG series can offset the reactive power demand of escalators and air conditioning units, thereby reducing kilovolt-ampere (kVA) consumption by 15-20%. This not only reduces operating costs, but also improves the building's energy efficiency rating, in line with sustainable development goals.The reactor's high short-circuit current withstand capability is particularly important in data centers, where uninterruptible power supply is essential. By limiting fault current during capacitor switching, it prevents voltage sags that can interrupt server operations. Its rugged design meets IP20/IP44 standards, ensuring reliable operation even in dusty or humid environments common in commercial locations. By integrating the CKFG series, building managers can gain enhanced circuit protection and regulatory compliance (such as EN 61000-3-2) while providing stable and efficient power to tenants and critical infrastructure.
Industrial automation and manufacturing facilities
The CKFG-1.2/0.25-6% series low voltage series reactor is designed to address the critical challenges of harmonic distortion and reactive power imbalance that frequently disrupt operations in industrial environments. In manufacturing plants, large motors, variable frequency drives (VFDs), and welding equipment generate significant harmonic currents (such as 5th, 7th, and 11th harmonics) that can cause transformers, capacitors, and other electrical components to overheat. By strategically installing this 7% aluminum wire impedance reactor in series with a capacitor bank, industrial systems can reduce harmonics by creating a low impedance path for the target harmonic, thereby preventing resonance and capacitor failure.In addition, the role of the reactor in reactive power compensation is critical. Industrial loads often operate at low power factors (as low as 0.7), which can increase energy losses and fines for the power sector. The CKFG series stabilizes the power factor at ≥0.95 by balancing inductive and capacitive reactive power, thereby reducing kVA demand and optimizing energy efficiency. This is particularly important in industries such as steel production and cement manufacturing, where fluctuating loads and high inrush currents threaten the life of equipment. The reactor's rugged design, corrosion-resistant fixtures and vacuum-impregnated windings ensure reliable operation in harsh environments, minimizing downtime and maintenance costs.In terms of circuit protection, the reactor limits the closing inrush current during capacitor switching, preventing voltage spikes from damaging sensitive machinery. Its ability to suppress transient overvoltages complies with international standards (such as IEC 61000-4-5), making it an essential component for plants subject to strict power quality regulations. By integrating the CKFG series, industrial facilities can not only improve equipment reliability, but also meet energy efficiency requirements, thereby achieving long-term cost savings.
Renewable Energy Integration and Microgrids
In solar farms, wind turbines and energy storage systems, power electronics (e.g. inverters, converters) introduce harmonic pollution and voltage instability, complicating grid connection. The CKFG-1.2/0.25-6% series addresses these challenges by suppressing the harmonics generated by renewable energy, ensuring compliance with grid standards and minimizing interference with neighboring systems. For example, in photovoltaic (PV) installations, the reactor's 7% impedance ratio effectively filters out the 5th and 7th harmonics common in solar inverters, preventing harmonic amplification and capacitor performance degradation.Additionally, reactors play a dual role in reactive power management. Renewable energy systems often require dynamic reactive compensation to stabilize voltage during fluctuating generation. By coupling the CKFG series with capacitor banks, microgrids can achieve seamless reactive power support, thereby improving grid stability and increasing the penetration of intermittent energy sources. This is critical for off-grid applications, where voltage regulation is essential for reliable operation of critical loads.The reactor features a low-loss aluminum wire structure that improves energy efficiency, reduces heat dissipation, and improves overall system performance in high-temperature environments common in solar installations. Its compact design also makes it easy to integrate into existing or retrofit energy storage systems, ensuring scalability as the renewable energy portfolio expands. By reducing harmonic distortion and optimizing reactive power flow, the CKFG series enables renewable energy projects to meet grid connection standards (such as IEEE 519), thereby promoting sustainable and reliable power generation.
