Matrix Series D Harmonic Filters

Typical Applications Use Matrix Harmonic filters to minimize harmonic current distor- tion in these and other 6-pulse rectifier applications: —Fans and Pumps —Water Treatment Facilities —HVAC Systems 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 tech- niques, 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. Matrix Filter enables most AC drive systems to comply with the voltage and current distortion limits outlined in IEEE 519. 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. —Storage – 40°C to 90°C —Operating – 40°C to 50°C —Altitude: 1000 meters maximum —UL approved – File E191686 for U.S. and Canada Minimum System Requirements to Achieve Performance Levels —Source Impedance: 1.5% minimum to 5% maximum —System voltage: 480 volts (line to line) +/– 10% —Frequency: 60 Hz +/– .75 Hz —Balanced Line Voltage: within 1% —Background Voltage Distortion: 0% THVD Product Specifications —Input Voltage 480 Volts +/– 10% —Ambient Temperature: —AC or DC Motor Drives —Rectifier type welders —Induction Heating Equipment —UPS Equipment —Elevators

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 below 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.
