When we talk about modern power systems, two technical domains often overlap but are not always fully understood together: electromagnetic compatibility (EMC) and power quality. Both play crucial roles in ensuring that electrical and electronic equipment perform reliably and efficiently. For companies and industries adopting Static Var Generators (SVGs) and Active Harmonic Filters (AHFs)...
As the world accelerates toward cleaner energy, the grid is being asked to carry far more than it was ever designed for. Solar parks, wind farms, and EV charging stations are connecting at record speed. On the surface, this looks like a straightforward victory for decarbonization. Yet behind the scenes, one invisible factor quietly determines whether this energy transition can succeed: power quali...
SVG Parallel Operation Test via CAN Communication Test Objective This test aimed to verify the performance and stability of multiple SVG (Static Var Generator) units operating in parallel via CAN communication when internal CTs are not used. Specifically, eight SVG modules were tested to evaluate their operation, communication reliability, and reactive power compensation consistency under CAN-base...
Using Medium Voltage SVG in the metallurgical industry is not an "option," but a "necessity" concerning economic efficiency, production stability, and social responsibility. We can use a simple analogy to understand this: The power grid of a metallurgical plant is like a main water pipe supplying all equipment. High-power impact loads like electric arc furnaces and rolling mills are like gian...
The metallurgical industry is a typical "severely affected area for power quality," and it is also where SVGs can deliver the most significant benefits. My explanation will be divided into two main parts: Governance Effects and Key Considerations. Part 1: The Governance Effects of Medium-High Voltage SVG in the Metallurgical Industry Production processes such as Electric Arc ...
Load Characteristics and Power Quality Issues in Commercial Buildings The main "sources of pollution" in commercial buildings include: Energy-Efficient Devices: Large quantities of LED lighting drivers, compact fluorescent lamps (CFLs), variable frequency drives (VFDs) for HVAC, and elevator VFDs. IT and Data Centers: Servers, computers, UPS (Uninterruptible Power Supplies), switching po...

The Challenge: High Harmonics, Failed Capacitors, and Unstable Production Zhejiang Jinjia Special-Shaped Copper Co., Ltd., located in Changxin...
Have you ever been troubled by these frustrating issues? Production lines in your factory halting without warning, causing massive financial losses? Lights in your office building flickering inexplicably, servers restarting frequently, putting data at risk? Receiving shockingly high electricity bills every month, with unexplained "penalty" charges? Electrical equipment overheating, lifespan shorte...
