Even‑Order Harmonics Are Silent Killers – Here’s How Active Harmonic Filter Delivers the Cure Most power quality discussions focus on odd harmonics like the 3rd, 5th, and 7th. But even‑order harmonics – 2nd, 4th, 6th, and beyond – are equally dangerous, often more damaging, and far harder to eliminate with traditional passive filters. They creep into your system from rectif...
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...
