Transformer Overheating from Harmonics: K-Factor vs AHF Mitigation In heavy industry, large data centers, and plants packed with VFDs and six-pulse rectifiers, a distribution transformer can run within its nameplate kVA and still develop abnormal temperature rise, oil-temperature alarms, or accelerated winding insulation ageing. The usual load-current check misses the frequency content of that cur...
Installing an Active Harmonic Filter (AHF) or Static Var Generator (SVG) is not simply a matter of choosing the correct current or kVAr rating. In factories, data centers, commercial buildings and infrastructure projects with multiple transformers or bus sections, the location of the equipment can directly affect compensation performance. Should one large AHF or SVG be installed at the main low-vo...
