Active Harmonic Filter for Welding Machines Welding machines are common in factories, workshops, steel plants, automotive production, shipyards, and metal processing sites. They are useful machines, but they can create serious power quality problems. The main issue is welding machine harmonics. Modern welding machines often use power electronic converters. These converters do not draw current in a...
Summary Discover how YT Electric’s advanced AHF and SVG systems eliminate harmonic interference, improve power factor to 0.99, and protect your industrial assets from invisible electrical threats. 1. The Global Power Quality Crisis: A $150 Billion Problem In the era of Industry 4.0, high-tech manufacturing, data centers, and automated production lines demand unprecedented elect...
Capacitor bank overheating is a common problem in modern electrical systems. Many facilities install capacitor banks for power factor correction, but the capacitor bank still runs hot, trips, or fails early. In many cases, capacitor bank overheating is caused by harmonic distortion. Harmonic distortion puts extra electrical stress on the capacitor bank. A capacitor bank is designed to supply react...
Modern agriculture is undergoing a profound electrification revolution. Irrigation pumps, grain dryers, greenhouse climate controls, and automated feeding systems are now standard equipment on farms worldwide. These tools bring efficiency and productivity, but they also introduce a hidden problem: harmonic distortion. You may have heard of "harmonics," but you might not realise they ar...
Medium Voltage Harmonic Filters: A Complete Selection Guide Medium voltage harmonic filters help industrial facilities, renewable energy plants, utilities, and infrastructure projects control harmonic distortion in their electrical systems. Harmonics can reduce power quality, increase equipment losses, create overheating, and interfere with normal system operation. A correctly designed harmonic fi...
Your UPS (Uninterruptible Power Supply) is supposed to be your safeguard—the insurance policy that keeps your critical operations running when the grid fails. But here's the irony: that very same UPS might be quietly damaging your equipment, inflating your electricity bills, and threatening the stability of your entire electrical system. How? Through harmonic distortion. Let's break dow...
Power Quality in Steel Mills — A Silent Threat to Production Steel manufacturing is one of the most energy-intensive industries in the world. Within a typical steel mill, you will find a diverse range of electrical loads: water pumps circulating cooling systems, medium-frequency induction furnaces for melting, overhead cranes for material handling, LED lighting for workspaces, rolling mills,...
A plastics extrusion plant in Ohio replaced motor starters with VFDs and cut drive energy use by 4%. Three months later, its 1000 kVA transformer ran 18 K above nameplate temperature, two capacitor banks tripped on overcurrent, and the utility applied a power-factor penalty. THDi on the 480 V bus measured 32% at full production. Adding capacitors would make that worse, not better. The fix i...
