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...
When Power Quality Equipment Must Also Be Quiet A Static Var Generator is normally evaluated by reactive power capacity, response time, power factor control and harmonic compensation. In many installations, the equipment room adds another requirement: the solution must also control noise, dust exposure and maintenance demands. YT Electric’s Fanless Static Var Generator uses natural he...
SiC MOSFET Active Harmonic Filter for THDi Correction A 1,000 kVA transformer feeding six-pulse VFDs, spot welders and single-phase loads is a textbook harmonic source. Field measurements on such busbars typically show current THD of 25–40 % at the PCC, with the 5th and 7th orders dominant. Third-order currents add up in the neutral conductor and overheat it. Fixed capacitor banks rar...
