This invention significantly reduces the harmonic content of the current waveform to an operating Electric Arc Furnace (EAF).  The net effect of this reduction is to allow more of the power to be delivered to the EAF at the line frequency.  The compensated EAF will cause significantly less disruption to the utility electrical distribution system than would an uncompensated EAF or an EAG compensated by conventional methods.
