Harmonic Suppression Furnace Transformer Solution
​Problem Analysis​Modern electric furnaces (especially arc furnaces, medium-frequency furnaces, and power-frequency induction furnaces) generate substantial higher-order harmonic currents that inject into the grid during operation due to their nonlinear load characteristics (e.g., violent fluctuations of electric arcs, rectification/inversion processes). These harmonics cause:​Grid Pollution: Distorted grid voltage waveforms (increased THD), affecting the normal operation of other sensitive equi
