The Electric Induction Furnace is a type of melting furnace which uses electric currents to melt and refinethe metal such as copper, lead aluminum, etc. Today, India ranks fifth in the world in EIF-based steel production and theproduction of steel by EIF is increasing adopted by Steel Industries .As the popularity and use of EIF in the industryincreases, so does the power quality problem as a result of this progress. The EIF operation causes harmonic, interharmonics, voltage flickers, voltage instability and reactive power burden. The induction furnace significance heavycurrent within a view of distortion in the current waveform, this heavy distorted current effect distortion in the systemvoltage. Due to the insulation limitations at 11 KV lines, for modern Power Quality where the Analyzers has to capturethe exact distorted voltage waveform. This induction heating furnace has problem such as low power factor, insufficientload, low efficiency and high system losses especially capacitor loss that are effected frequent damage to the parallelcapacitor. Pure active filters were planned to mitigate passive filter disadvantages, while this is costly method.Sometimes rate power of active filter should be 80 percent of load power .Because both pure active filters and passiveare not an ideal solution. The simulation model of the induction furnace was implemented in MATLAB software andoutput wave form analyzed.
