Verimliliği ve Güç Faktörünü En Üst Düzeye Çıkarın
A Reactor (also known as an inductor or choke) is an electrical component that uses inductance to limit, smooth, or filter current in a power system. By introducing controlled inductive reactance into the circuit, a reactor suppresses harmonic currents, limits inrush and short-circuit current, protects motors and drives from voltage spikes, and prevents resonance when combined with power capacitor banks — making it a core companion device for power factor correction, harmonic filtering, and variable frequency drive (VFD) systems.
| Fonksiyonlar | Description |
|---|---|
| Harmonic Suppression | Blocks high-frequency harmonic currents from motors, VFDs, and rectifiers, protecting capacitors and sensitive loads from waveform distortion. |
| Capacitor Bank Detuning | Works with power capacitors (typically 5.67%, 7%, 14% detuning rate) to shift the resonance point away from dominant harmonics, preventing harmonic amplification. |
| Inrush & Switching Current Limiting | Restrains the surge current generated when capacitor banks or motors are switched on, reducing stress on contactors, fuses, and busbars. |
| Motor & VFD Protection | Smooths PWM output waveforms and dampens dv/dt and reflected-wave voltage spikes, extending motor winding and cable insulation life. |
| Voltage Spike & Surge Suppression | Absorbs transient voltage disturbances from switching operations, lightning, or grid faults, protecting downstream equipment. |
| Power Quality Improvement | Reduces THD (Total Harmonic Distortion) on the supply side, helping systems meet IEEE 519 / IEC 61000 harmonic limits. |

Where Our Reactors Proven Results
A reactor is not a one-size-fits-all device. Below are typical scenarios where our reactor reduces reactive energy penalties, improves voltage stability, and lowers harmonic distortion.
Our reactors use grain-oriented silicon steel laminations and precision copper/aluminum winding to minimize core and copper losses. This keeps operating temperatures low and improves overall system energy efficiency, even under continuous full-load operation.
Engineered with a wide linear working range, ZHIMING reactors maintain stable inductance even under current surges or harmonic-rich conditions, ensuring reliable detuning performance and consistent protection for capacitor banks and drives.
Dry-type, resin-impregnated or vacuum-varnished construction eliminates oil leakage risk. Reactors are built with flame-retardant insulation materials and can be fitted with thermal protection (PTC/PT100) for overheat monitoring and automatic disconnection.
Optimized magnetic circuit design and lightweight core construction reduce the overall footprint compared to conventional reactors, making installation in distribution cabinets, motor control centers, and retrofit projects easier and more space-efficient.
Designed and tested in compliance with IEC 60289 and other international standards, ZHIMING reactors operate reliably across an ambient temperature range of -25°C to +50°C, with a design lifespan exceeding 100,000 hours — matched to work seamlessly with our power capacitors and capacitor controllers for complete reactive power compensation and harmonic filtering solutions.

A low voltage power capacitor is designed for systems ≤1kV (e.g., 400V industrial panels), while a high voltage power capacitor operates at 1kV to 35kV, typically used in utility substations or large MV motor compensation. Their internal dielectric, terminal insulation, and discharge resistors differ accordingly.
You need three pieces of data:
Average power factor (from utility bill)
Target power factor (usually 0.95–0.98)
Monthly active energy (kWh) and reactive energy (kVARh)
Use the formula: Required kVAR = Active Power (kW) × (tanφ₁ – tanφ₂). Or simply send us 30 days of load data – we will calculate it for free.
Standard capacitors may overheat under harmonics. You need a detuned power factor correction capacitor with a series reactor (typically 7% or 14%). Our harmonic‑rated series is marked “HD” and includes over‑temperature protection.
Our power capacitor units are designed for 120,000–150,000 hours (over 15 years) at rated voltage and ≤45°C ambient. End‑of‑life signs include capacitance loss >10% or visible bulging – we offer free capacitance testing kits for bulk orders.
Yes. Custom voltages (e.g., 480V, 525V, 690V) and non‑standard kVAR steps are available with a minimum order quantity. Contact us with your specification sheet for a fast quotation.
