Koffler Electrical Mechanical Apparatus Repair, Inc. - Matrix Series D Harmonic Filters

Matrix Harmonic filters provide broadband reduction of harmonics. Matrix Harmonic Filters not only offer better performance over other broad band filtering and 18-pulse harmonic reduction techniques, they are also suitable for a wider range of applications. Matrix Harmonic Filters can be installed in either variable or constant torque drive applications and can be applied on either diode or SCR rectifiers. For any application other than variable torque applications, it is suggested that you contact the factory for filter selection.

Minimum System Requirements to Achieve Performance Levels

The Matrix D Filters typically achieve 5 % THID at full load and guarantee worst case current distortion at any load between 0 % and 100 %, will be 8 % THID or less at the filter input terminals. The Matrix D Series is typically used in place of applications requiring harmonic mitigation associated with 12- or 18-pulse rectifiers. The chart compares the performance of Matrix D Filters to 18-pulse rectifiers in real world applications, which include line voltage unbalance of 1 % to 3 % and loading conditions from 0 % to 100 %.

Matrix D Filter performs better than 18-pulse in normal operating conditions.

Applications
Select Matrix filters based on the horsepower (or kilowatt) rating for the adjustable speed drive or the combined current rating of all motors to be connected to the load side of the filter. For variable torque, DC drive or other applications consult factory for proper filter selection.

Source Impedance
If the source impedance is less than 1.5 % impedance, it is required that an input reactor of at least 1.5 % impedance be added in order to have guaranteed performance level. For best value and performance it is recommended that a 3 % line reactor be used whenever the source impedance is less than 1.5 %.

A complete harmonic analysis and product selection tool is available on the internet. Go to geindustrial.com and select Products, select Capacitors, choose Matrix Harmonic Filter and then select Energy Savings Calculator and Harmonic Estimator. Matrix Harmonic Filters are multi-stage low pass filters specially configured to avoid the attraction of harmonics from other sources on a shared power system. Matrix filters will not cause power system resonance. However, the configuration of the filter requires that only drives or equivalent loads be loaded on the output of a Matrix harmonic filter. One filter can be used with multiple drives. However, if there is a drive bypass circuit, there must be one filter per drive and the filter and drive combination must be bypassed. Matrix Harmonic Filters are available in a NEMA 1, NEMA 3R or as a modular design preassembled onto panels for subsequent assembly into customer supplied cabinet.
