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...
As electric vehicle (EV) adoption continues to grow across Europe, Italy is accelerating its efforts to expand charging infrastructure. To support this transition, YTElect recently delivered 300 units of 22 kW three-phase AC charging stations to an Italian distributor — a major step toward strengthening the country’s public and private charging network. This deployment underscores YTEl...
IN any system containing nonlinear loads that use phase-angle control or abrupt switching, particularly those that draw a non-sinusoidal current. The specific range of "2nd to 51st" is a classic signature of certain technologies.Here are the most common places where you would find such a wide harmonic spectrum: 1. The Classic Example: Thyristor-Controlled Reactor (TCR) in SVC Plants This is the mo...
Case Study in Jiangsu: Hybrid Reactive & Harmonic Compensation Cabinet for Non-Woven Textile Manufacturing Quick Answer: In high-speed synthetic fiber and non-woven fabric manufacturing plants, high-frequency spunmelt extruders, calendering roll induction heaters, and distributed VFDs generate severe 5th and 7th harmonic currents (THDi > 22%) combined with fast-fluctuating reactive power sw...
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...
How a Copper Manufacturing Plant Solved Severe Harmonic Issues with SVG + APF Technology Real-world case study: Improving power quality, restoring capacitor operation, and eliminating production disruptions at Zhejiang Jinjia Special-Shaped Copper Co., Ltd. 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...
Take a look around your modern office: the efficient LED lights, the humming server racks, the computers on every desk, the projectors in meeting rooms... They are all symbols of your business's efficient operation. But what you might not know is that these modern devices are also invisible "sources of pollution," quietly increasing your operational costs and even threatening your business securit...
