Performance Guarantee
Select and install the appropriate HarmonicGuard®Passive Harmonic Filter Kit
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 HGP Series filters
at full load, and less than 8% at 30% 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 HGP 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 3% AC line reactance at full load.
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 HGP filter if there is harmonic
voltage distortion already on the system.
If higher levels of harmonic voltage distortion (2%-5%) are present, please use
the high voltage distortion wiring of the HGP filter kit.
*For PQconnect: To run PQvision software, minimum system requirements
are Windows 7 and 1280 x 720 resolution.

3.0 Pre-Installation Planning
Verify the Application
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. The published HGP 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 HGP 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 nonlinear 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 HGP harmonic filters for your non six-pulse diode front end VFD
applications.
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.
Recommendations Kit Usage
Panel design using a TCI HGP Filter Kit should be performed with appropriate engineering
supervision so the design meets the requirements based on materials utilized in the construction of
the panel, wiring practices followed by your shop, and the actual ambient conditions of the
components for each application.

SCCR Ratings
If you need an SCCR greater than the default values of components, for example, 10 kA for terminal
blocks or 5 kA for contactors, pay attention to component selection and circuit fusing. Contactors
need to be protected by line or branch tuned circuit fusing based on their published SCCR.
TCI HGP Kit include reactors that are not required to have a short circuit current rating per UL 508A
SB4.2.1 Exception 1.
See Table 2 for line fuse requirements to complete 100 kA SCCR. Larger kits include dry-type
capacitors that are not required to have a short circuit current rating per UL 508A SB4.2.1 Exception 1.
Small horsepower HGP kits (see Table 2) have a line fuse requirement in order to reduce incoming 100
kA short circuit current to 10 kA on the panel suitable for the oil filled capacitors used on these small
horsepower ratings.

Filter Wire Sizing
Wire Sizing
Wires need to be sized based on current to be carried, wire insulation temperature rating, panel
temperature rating, bundling of wires, and appropriate codes and standards. Wire size between the
power source and the filter line reactor, as well as the line reactor and the drive input, are based
rated filter line current. Wire size in the branch circuit is based on rated tuned circuit current. If the
capacitor wiring is split into separate capacitor branches, the current each branch carries is
proportional to the value of capacitance in each branch.

KDR Line Reactor Installation Instructions
Recommendations and Considerations
When installing the KDR Line Reactors on the INPUT side of the VFD, please use the following
guidelines when wiring the unit:
The KDR Line Reactor is a 3-phase device and should be wired in series and positioned on the input
side of the VFD.
All Terminal Block connectors will be marked. A1, B1, and C1 are the input terminals where the 3
phases of incoming power are to be wired. The tap for the filter connection will be marked AT, BT,
and CT. Output terminals will be marked A2, B2, and C2. Do not swap input and output terminals.
Units with copper bus or ring lug terminals are not marked. Wiring from the output terminals should
connect to the input of the VFD.
Refer to NEC (National Electrical Code) wiring practices for appropriate wire sizes for your application.
TCI recommends that these reactors be wired and located as close to the front end of the VFD as
possible to have the greatest success in both protecting the VFD as well as mitigating line harmonics.
We recommend this be 10 feet of cable or less.
Reactors generate a lot of heat in normal operations and their surfaces get very hot. In standard 40°C
ambient or less installations, a clearance of 3 inches on all sides of the reactors and its enclosure is
recommended for assisting in heat dissipation. This is a general guideline for typical applications. If
the reactor is being installed next to a heat sensitive instrument or control device, we recommend

reviewing specific requirements on heat limitations. Line reactor heat loss information is available on
the web at https://transcoil.com/products/kits-page/hgp-kits.
These reactors are designed to be floor-mounted or wall-mounted. Large open-style devices should
be panel mounted by incorporating a bracket that would act as a shelf to support the reactor and/or
enclosure. When installing an open style device in an existing control cabinet, drive cabinet, motor
control center, or other large enclosure, the reactor should be mounted in the lower half of the cabinet
to prevent hot spots or pockets of heat. Locating the reactor in the lower half of the cabinet typically
allows better thermal dissipation and heat convection. Reactors with ducts should be mounted
vertically for proper cooling.
NOTE: If the PQconnect PCB board is included in your kit please read through mounting and wiring
practices found in section 5.0.
Line Reactor Wiring
In the higher performance HGP design, tapped line reactor wiring is more critical than standard line
reactor designs. Before tapped line reactors, it did not matter if you connected the A1, B1, C1 to the
line side or the drive side, however, on the HGP, the terminals cannot be swapped. Incorrect wiring of
the line reactor will result in poor harmonic mitigation and could damage the reactor. Consult the
reactor drawing for your line reactor to verify proper filter wiring. All line reactor drawings are available
on the parts web page:
https://transcoil.com/products/kits-page/hgp-kits
The incoming line must be wired to the winding start noted as A1, B1, and C1 in the reactor
drawing. The tuned circuit is typically connected to the winding tap noted as AT, BT, and CT in
the reactor drawing, or it may be connected to the winding end noted as A2, B2, and C2 in the
reactor drawing.
•In small line reactors with nine position terminal blocks, the terminal block is wired A1, AT,
A2, B1, BT, B2, C1, CT, and C2 from left to right.

•In small line reactors with six position terminal blocks, the terminal block is wired A1, A2,
B1, B2, C1, and C2 from left to right. The tap lugs AT, BT, and CT extend out from the front
face of the coil.
Figure 4 – Six Position Terminal Block
•In line reactors where current exceeds terminal block capability, ring lugs are used for all
three terminations. Note from the drawing below, the tap connection is at the lower right
side of the coil.
Figure 5 – Ring Lug Terminations
•In larger line reactors, all three terminals extend from the front of the reactor, and are
constructed from copper bus bar terminals. Unless you are an expert on start and finish
windings, consult the reactor drawing to be sure which terminal is which. In the example
below, the tap winding is on the bottom of the coil.
