Fuse Monitor with Contactor Option (F)
The Fuse Monitor with Contactor Option includes a voltage monitor module and relay that can be
connected to a VFD or other device. The fuse monitor will indicate a fuse failure and communicate this
condition through the relay to a connected device.
This option includes a contactor, control power transformer, and connection terminals in the filter
circuit which allows the VFD user to control the insertion of this circuit through the use of a relay
contact in the VFD. It is recommended that the drive contact be programmed to open the contactor
below 33% motor power. For variable torque (fan) loads this will be approximately below 70% speed,
so the at-speed contact may be used. This reduces the possibility of leading power factor interacting
with other devices on the power system. Contactor logic should also maintain the contactor closed in
cases where the VFD is bypassed and the filter is not bypassed.
Product Description
HGP F Option Filter
The HGP harmonic filter is a drive-applied harmonic filter designed and developed by TCI to reduce
the harmonic currents drawn from the power source by VFDs. The HGP harmonic filter is for 480 volt
systems (60 Hz). It is suitable for use with 3-phase diode bridge rectifier loads such as PWM AC
drives.
The HGP harmonic filter 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 VFD. The filter is a stand-alone device that can be furnished in its
own enclosure and mounted adjacent to the VFD. It is also available on an open panel for mounting
within an enclosure with the VFD or other equipment.
The HGP F Option consists of the following standard features and components:
♦ A KDR tuned series reactor.
♦ A TCI 3-phase tuning reactor specifically designed for the HGP filter.
♦ High-endurance, harmonic-rated capacitors.
♦ Bleeder resistors to ensure safe capacitor discharge upon filter shutdown, located on
capacitors.
♦ Filter enable/disable contactor with protection and drive interlock provisions.
♦ Cooling fans (on select models) to ensure adequate cooling and safe operating
temperatures.
♦ Control power transformer
♦ Compression terminals for ease and integrity of all power and control wiring.
♦ Fuses
♦ Contactor
♦ Voltage monitor module to report status of fuses to control
