Abstract: This paper presents the electromagnetic pollution produced by the line frequency coreless induction furnaces in the power supply network. We analyzed a furnace with 12.5 t capacity of cast-iron. The measurements have been made in the secondary of the furnace transformer, using the CA8334 three-phase power quality analyser. Experimental results emphasized the presence of harmonics and interharmonics in the phase voltages and harmonics in the currents absorbed from the network. The operation of analyzed furnace also produces unbalance. Further to the harmonic analysis of the signals measured in the furnace installation, we have been proposed some optimization methods for its operation, in such way to comply with the European norms of Electromagnetic Compatibility (EMC).
Keywords: Harmonics, Unbalance, Power quality measurement, Induction furnace
