摘要: This paper presents a study about power quality problems generated by line frequency coreless induction furnaces. We analyzed furnace with 12.5 t capacity of cast-iron. The measurements have been made in the primary transformer, on MV line, using CA8334 three-phase analyser. Experimental results emphasized presence harmonics and interharmonics phase voltages currents absorbed from network. Further to harmonic analysis measured signals, we proposed some optimization methods for operation furnace, such way comply European norms Electromagnetic Compatibility (EMC).
