LSVG
Series Low Voltage Static Var Generator
Rated Voltage:0.4kv
Rated Frequency:50/60HZ
Function:Compared with the traditional solution, it increases the necessary harmonic control ability, which solves the influence caused by the harmonic while effectively dealing with the reactive power problem, and completely solves the majority of power quality problems of users with the highest cost performance.
Application:Machinery manufacturing, metallurgy, mining, coal, chemical industry.
Installation:indoor\outdoor
Product feature
One machine with multiple functions, which can deal with harmonics, reactive power and three-phase unbalance at the same time
Modular design and cabinet design have a variety of installation methods, which can be embedded and installed or configured with standard cabinets according to the user's system conditions
The maximum capacity of a single cabinet is 500kvar, which covers a much smaller area than the compensation scheme based on traditional capacitance. Two devices in parallel can cover the comprehensive compensation capacity of all low-voltage transformers
Input voltage and frequency range, suitable for domestic power grid fluctuations, continuous reactive power compensation and harmonic filtering
DSP+FPGA three-core processor unit control, real-time tracking, dynamic compensation, fast dynamic response (μs level response)
Compared with traditional capacitance compensation scheme, LSVG can realize capacitive and inductive bidirectional compensation, reactive power compensation is continuous compensation, compensation error less than 1% for the grid system is infinite impedance, does not affect the grid system impedance. The output waveform is accurate and does not affect other devices
Low power consumption (less than 2% of rated power), actual efficiency > 98%
Real-time flexible monitoring, through the communication interface computer remote monitoring, easy to centralized control and management, standard remote monitoring interface, support remote switch.

FAQ
Q: What is APF Working principles ?
A: 1.External current transformer(CT)could detect real-time load current .
2.Internal DSP calculates and analyzes the reactive power content of the system.
3.Control PWM to send signal to IGBT to generate reactive power compensation current for power factor compensation.
Q: How to choose the model number?
A:Please specify the APF rated voltage,frequency ,3p3w/3p4w,rated capacity,CT sampling position(grid or load side).
Q: How is the usage effect?
A: It can resolve harmonic current problem, the below picture is comparison.
