The OMHG7 - drive applied harmonic filter its called an "OMHG7" shall contain a tuned circuit designed to remove harmonics generated within a power distribution system while improving the system power factor. The OMHG7 designed to minimize the possibility of system problems associated with power factor correction in the presence of harmonic distortion.

OMHG7 Consists of inductive and capacitive elements arranged in a series configuration and are tuned to resonate just below the harmonic frequency for which they are designed to filter. The OMHG7 has its minimum impedance at the tuning frequency. At frequencies above the tuning frequency, the OMHG7's impedance is inductive, therefore, it cannot adversely react with the parasitic inductance of the power system. The inductance in the OMGH7 combined with the series line reactor, acts to limit current surges between the capacitor and other plant electrical equipment and shall minimize the possibility of equipment or capacitor damage due to such surges.

The harmonic filter in combination with the adjustable frequency drive shall Meet all requirement specified in the 1992 edition of IEEE Standard 519 for individual and total harmonic Voltage and current distortion. The point of common Coupling (PCC) for all. Voltage and current harmonic calculations and measurement shall be the input terminal of the harmonic filter.
