Our solution
Professional Services Tailored for You Reliable Solutions
CNBYG power quality solutions are deployed worldwide in the most demanding electrical environments — where harmonic distortion and poor power factor cause real operational and financial losses.
Automobile Manufacturing
After installing SVG+APF on a large number of welding robots and variable frequency conveyor belts, the power factor improved from 0.72 to 0.99, saving more than 10,000 yuan in electricity costs per month, and eliminating welding machine malfunctions.
Data Center
UPS and switching power supplies generate a large amount of third and fifth harmonic waves. After installing the APF, the current in the neutral line decreases by 60%, and the temperature of the transformer drops by 15℃.
Photovoltaic / Charging Station
To solve the problems of reactive power backflow and voltage fluctuations caused by intermittent power generation and charging piles, SVG achieves bidirectional and rapid compensation.

Quick answers to common questions about our products, technical capabilities, and services. Can’t find what you’re looking for? Contact our team directly.
Check the following three items:Cooling fan statusCheck whether the cooling fan is blocked or stuck, which may trigger over-temperature protection.Grid voltage fluctuationCheck whether the grid voltage fluctuation exceeds ±20%, which may be outside the normal operating range.Harmonic distortion rateCheck whether the harmonic distortion rate exceeds 30%, which may trigger the current-limiting protection threshold.
This alarm indicates that the current transformer direction is reversed.Please swap the two secondary-side CT wires, for example by exchanging S1 and S2.You can also use a multimeter or power quality analyzer to check the phase angle. Under normal conditions, the angle between the A-phase current and voltage should be within ±5°.
The choice depends on the installation environment and application requirements.Wall-mounted type:Suitable for independent or small-capacity applications, such as residential buildings, commercial spaces, or compact electrical rooms.Rack-mounted type:Suitable for industrial cabinets and larger systems. Multiple modules can be combined for higher capacity and flexible expansion.
