A vehicle body shop can run hundreds of welding points per minute, while robots, presses, conveyors, paint lines and HVAC systems change their electrical demand continuously. The production line may look mechanically stable, but the electrical load seen by the transformer is not. Rapid reactive-power changes, low power factor, voltage fluctuation and harmonic current can appear whenever several we...
APFC Panel Troubleshooting: 7 Common Faults and How to Fix Them An automatic power factor correction panel may begin switching incorrectly, miss its target or repeatedly trip capacitor stages. A newly commissioned APFC panel can also fail from its first day. The cause is not always a defective capacitor. CT installation, controller settings, harmonics, switching components and changing load...
Hybrid SVG + Capacitor Bank Reactive Power Compensation Your capacitor bank trips once a month, the contactor welds shut, and the DISCOM bill still carries a penalty line. The 250 kVA rectifier load from your new VFDs is the reason, and adding more capacitors will make it worse. A hybrid SVG + capacitor bank system fixes the root cause instead of compensating for it. This article explains why fixe...
How to Maintain and Care for Your Electrical Power Equipment？ Modern electrical systems rely heavily on advanced devices like Static Var Generators (SVGs) and Active Harmonic Filters (AHFs) to ensure stable power quality, energy efficiency, and equipment longevity. However, even the most sophisticated systems require regular maintenance to perform optimally. Neglecting upkeep can lead to inefficie...
