Transformer Overheating Explained: Why It Happens Below Rated Load A transformer can run unusually hot even when the connected load appears safely below its nameplate rating. Current may seem acceptable while winding or enclosure temperatures continue rising. This often happens because loading is assessed only in kilowatts or average amperes. Harmonics, imbalance, poor power factor and inad...
Active Harmonic Filter: Extend Transformer Life A 480 V transformer that runs within nameplate kVA can develop abnormal temperature rise when VFDs, UPS rectifiers, and switched-mode loads inject high harmonic current into its secondary bus. The transformer does not see only useful fundamental current; it carries distorted current through its windings, terminations, and neutral conduc...
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...
