SVG STATIC VAR GENERATOR MODULES
The GY-SVG Series Static Var Generator (SVG) is a high-performance, dynamic reactive power compensation device. It operates by continuously detecting the system voltage and load current, then using a high-speed DSP (Digital Signal Processor) to calculate the real-time reactive power demand. The SVG then drives its IGBT (Insulated Gate Bipolar Transistor) modules to output the required capacitive or inductive reactive current.
This achieves:
Fast, dynamic reactive power compensation
System voltage stabilization
Improved power factor
Reduced line losses and optimized power quality
The Basic Series covers capacities from 30 to 200 kVAr, featuring a compact, rack-mount design with standard cabinet widths. The small footprint ensures easy integration into commercial buildings and industrial power distribution systems.
CYLINDRICAL LOW VOLTAGE SHUNT CAPACITORS
Designed for power factor correction and voltage waveform improvement in 50/60Hz low-voltage systems. Suitable for both individual and centralized reactive power compensation.
Key features include high-quality BOPP film, composite metal spraying technology, and corrugated waveform design, ensuring excellent self-healing performance, low loss, and high current withstand capability.

INVERTER INPUT & OUTPUT REACTORS
Why Use VFD Reactors?
Variable Frequency Drives (VFDs) are widely used in industrial applications, but without proper protection, their reliability and lifespan are compromised. When paired with our reactors, you get:
Effective suppression of switching overvoltage and inrush currents, protecting the VFD from damage.
Reduced harmonic pollution to the power grid, improving the overall power factor and efficiency.
Clean, stable power delivery for consistent equipment operation.
1. Input Reactor (Line Reactor)
Installation: Between the power supply and the VFD rectifier
Key Benefits:
1.Limits current surges caused by grid voltage fluctuations and switching overvoltage, protecting the VFD.
2.Improves the system power factor.
3.Reduces harmonic pollution generated by the VFD rectifier.
2. Output Reactor (Load Reactor)
Installation: Between the VFD output and the motor/load
Key Benefits:
1.Absorbs harmonic components in the VFD output waveform.
2.Reduces motor noise and vibration.
