Performance Guarantee
Select and install the appropriate HarmonicGuard® Low Capacitance Harmonic Filter in a
variable torque, variable frequency AC drive application, within our published technical
specifications and we guarantee that the input current distortion will be less than or equal to
5% THID for standard HGL Series filters at full load. If a properly sized and installed filter fails
to meet its specified THID level, TCI will provide material for necessary modifications or
replacement filter at no charge.
HG filters can also provide similar performance in other drive applications such as constant
torque, DC drives and other phase-controlled rectifiers, but actual THID levels can vary by
load and/or speed and therefore cannot be guaranteed.
Consult factory for assistance when applying HGL filters on these types of equipment.
MINIMUM SYSTEM REQUIREMENTS:
The guaranteed performance levels of this filter will be achieved when the following
system conditions are met:
Frequency: 60Hz ± 0.75Hz
System Voltage: Nominal System Voltage (line to line) ±10%
Balanced Line Voltage: Within 0.5%
Background Voltage Distortion: < 0.5% THVD
The input VFD current waveform shall be consistent with that of a VFD with 5% AC
line reactance at full load and a 5% source impedance.
NOTE: The presence of background voltage distortion will cause motors and other linear
loads to draw harmonic currents.
Additional harmonic currents may flow into the HGL filter if there is harmonic voltage
distortion already on the system.

3.0 Pre-Installation Planning
Verify the Application
Make sure that the HGL filter is correct for the application. The voltage rating of the filter must
match the input voltage rating of the connected drive. The horsepower and current ratings of the
filter must be appropriate for the connected load.
HGL Drive-Applied Filter
The HGL is a drive-applied harmonic filter designed and developed by TCI to reduce the harmonic
currents drawn from the power source by VFDs. The published HGL voltage, Power (Hp or kW)
and current ratings apply to matching power (Hp or kW) rated standard VFDs with six-pulse diode
bridge rectifiers. The HGL may also be sized to filter other loads such as SCR six-step drives,
SCR Direct Current (DC) motor drives, thyristor furnaces, battery chargers, electroplating supplies
or other types of non-linear loads. In many cases, the filter power rating (Hp or kW) will differ from
load power rating (Hp or kW). Please contact TCI Technical Support for additional information
and support on sizing HGL harmonic filters for your non-six-pulse diode front end VFD
applications.
The HGL 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 HGL 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 HGL filter
•High-endurance, harmonic-rated capacitors
•Larger filters may have multiple tuned circuits. Consult fuse tables to determine if the
filter in question has “parallel” branches.
•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

HGL Filter Overview
The HarmonicGuard®Low Capacitance (HGL) Filter provides a low impedance path for the major
harmonic currents demanded by Variable Frequency Drives (VFDs). This greatly reduces the
amount of harmonic currents flowing through the electrical power distribution system, bringing
those harmonic currents in line with the IEEE-519 standard for harmonic distortion mandated by
an increasing number of utilities.
The HGL Filter includes branch fuses on the harmonic trap circuit capacitors. These fuses are
included in the design to prevent damage to the capacitors in the event of excessive harmonic
trap current if the filter is misapplied.

No Contactor Option (S)
The No Contactor (Standard) Option includes high quality harmonic-grade capacitors and line
reactors. This filter will meet most application requirements found today. This cost-effective
product is available as an open panel version, in a UL Type 1, UL Type 12, or in an UL Type 3R
enclosure. The open panel is perfect for inclusion in a MCC section or easy installation into
industry standard enclosures. The UL Type 1 enclosed units maintain the same vertical profile as
the open panel design. This design is perfect for applications where floor space is at a premium.
The UL Type 3R enclosure protects the filter from harsh conditions.
Contactor Option (C)
The contactor option shall allow the user to open and close a contact that will remove the
capacitors from the circuit. Operation shall be controlled through a contact input on the customer’s
equipment.
The Contactor 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 using a relay
contact in the VFD. It is recommended that the VFD 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.
Vibration Pad Option (V)
The Vibration Pad Option is intended for use in applications which require environmental noise
protection. The resilient mounting material is placed between the reactor and the interior of the
enclosure and dampens noise produced by the reactor.
The Vibration Pad option is available for all enclosure types.
Floor Stand Option (F)
The Floor Stand Option is intended for use in applications which require the HGL enclosure to be
elevated from the floor. The Floor Stand option consists of 12” steel feet available for Type 3R
enclosures 125hp and below.
Oilfield Duty Option (P)
The Oilfield Duty Option features components designed specifically for oil and gas field applications
to handle the additional electrical stress. Designed for cyclical loads these units will be available in
Type 3R enclosures and will be for use with HP ranges from 40 to 200HP.
Heater Option (H)
The Heater Option is intended for use in applications which require the environmental protection of
a NEMA 3R enclosure. The heater is mounted to the interior of the enclosure and protects sensitive
electronic equipment from the harmful effects of corrosion and condensation. When using a Type
12 or Type 3R Enclosure and in a high humidity environment, set thermostat to 37°C (100°F) or
max temperature below 37°C (100°F).
The Heater option is available for all 3R enclosures.
