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
