Product Description
HGP Drive-Applied Filter
The HGP is a drive-applied harmonic filter designed and developed by TCI to reduce the harmonic
currents drawn from the power source by VFDs. It is suitable for use with 3-phase diode bridge
rectifier loads such as PWM AC drives. SCR or thyristor loads such as DC drives would require a
different filter configuration outside the scope of this product offering. Please contact TCI Technical
Support for additional information.
The HGP is a passive filter connected in series with the input terminals of a VFD or several VFDs that
operate as a group. It is designed to provide a low impedance path for the major harmonic currents
demanded by the drive. The filter is a stand-alone device that can be furnished in its own enclosure and
mounted adjacent to the drive. It is also available on an open panel for mounting within an enclosure
with the drive or other equipment.
The HGP filters consist minimally of the following features and components:
♦ A KDR tuned series reactor to prevent system interaction and improve filter performance
♦ An L-C-L filter circuit with:
A TCI 3-phase tuning reactor specifically designed for the HGP filter
High-endurance, harmonic-rated capacitors
♦ Multiple tuned circuits on 700 HP to 900 HP
♦ Bleeder resistors to ensure safe capacitor discharge upon filter shutdown
♦ Cooling fans (on select models) to ensure adequate cooling and safe operating
temperatures
♦ Compression terminals for ease and integrity of all power and control wiring
♦ Fuses, sized to protect the capacitor wiring
