The OMHG7 - drive applied harmonic filter is 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 is 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 fusing tuning reactor and capacitor shall be in parallel with the VFD. The VFD Shall remain operational in the event of a failure of the capacitors or other condition causing the fuses to open The Voltage regulation at the VFD terminals and attributable to the filter shall not exceed 5% filter with greater them 10% Voltage drop and filters that have capacitors in Services with the VFD are not acceptable .
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. 

Features: 
(1) Limited to 7% Distortion (typical results of 5-6% TDP) Total demand Distortion. 
(2) Superior performance at 100% and 50% Load. 
(3) THD levels are consistently held Low. 
(4) High Quality capacitor designed built and tested specifically for use in harmonically rich environments. 
(5) Easy installation: Fits easily in to VFD Motor control centers and ships ready to install. 
(6) Uninterrupted operation: The drive continues to operate in the event of OMHG7 shutdown. 
(7) In the operating range full Load to half load the power factor shall be 0.98 lagging to 0.95 leading.
