SECTION 3 LINE REACTORS
The RM Line Reactor . . .
CORE
The quality and performance of a line reactor is
fundamentally dependant on its ability to withstand
harmonics and transients in what is clearly a difcult
environment. The bonding and clamping techniques
of the gapped core also signicantly impacts its
performance characteristics.
HPS has paid particular attention to these
basics to ensure both reliable and consistent
performance.
Core materials, manufacturing and assembly
processes have been carefully evaluated to produce
optimum losses and sound levels necessary for this
product.
COILS
Conductors are
precision wound for
optimum short
circuit withstandability
and electrical balance
are used throughout
the RM line. Choice
of conductors, winding
techniques and cooling
ducts are precisely
selected to assure the
highest continuous,
reliable performance.
INSULATION
SYSTEM
permissible continuous ambient temperature of
60°C. These temperature tests are all measured at
150% rated 60 Hz current. For further information on
temperature rises, please consult our sales ofces.
VPI IMPREGNATION
Every reactor is fully VPI vacuum and pressure
processed with VT (vinyl-toluene) Polyester Resin.
This modern, vinyl-toluene based resin with its
thicker build, offers signicant benets for electrical,
mechanical and thermal properties.
This impregnation process and material results
in a much improved dielectric constant, dissipation
factor, bonding
strength and dielectric
breakdown (volts per
mil) than any other
impregnation material
including the more
traditional oil modied
epoxies and varnishes.
Vacuum
impregnation is
considered vital for the
integrity of electrical
equipment located
in such sensitive
locations. The core
and coil assembly is
nished with a clear
resin.
TERMINATIONS
SECTION 3
HPS Line Reactors are designed to meet the
most difcult temperature environments. On units
up to 160 amps, RM line reactors have a 115°C
temperature rise designed for 200°C Insulation
Class. This results in a permissible 24 hour
maximum ambient of 50°C and an average of 40°C
continuously.
On units larger than 160 amps, Class 220
Insulation is used throughout with a maximum

Custom connections are provided for in several
ways. Finger-proof-terminal blocks are provided on
three model ranges, and terminal pads are supplied
on higher current ratings. Refer to the dimensional
summary for details. All connections are brazed to
ensure electrical integrity.

. . . Features of Construction
ENCLOSURES
Enclosed reactors are standard as either NEMA
2 or 3R. Units in NEMA 3R enclosures are suitable
for oor or wall mounting. Wall mounting is available
on NEMA 3R units up to 600 lbs. Please consult
customer service for details.
Enclosures are nished with a 7 stage
phosphate process with baked enamel ANSI 61 grey.
RM SERIES
This approval is inclusive to 2000 amps and 8.6
kV class, and may be of interest for any special
applications.
Our products are built in accordance with
and meet UL 508, UL 506 and CSA C22.2 NO.66
standards.
SECTION 3
QUALITY CONTROL
Every reactor is production line tested in
accordance with the requirements for UL, ANSI,
NEMA and CSA. This conrms that every unit meets
our highest expectations for Quality Assurance.
Additionally, line reactors have been short
circuit tested at a certied laboratory to conrm the
withstandability of our reactors to short circuits that
may be present in a distribution system. Tests were
done in accordance with ANSI C57.12.91 at 25 times
rated current for 2 seconds. Those test results are
available upon request successfully withstanding
this test ensured that the RM line reactor will survive
power stresses such as short circuits that may be
present in a distribution circuit.
UL and CSA CERTIFICATION
INPUT AND OUTPUT SIDE REACTORS
HPS three phase Line Reactors are designed
for both the input and output side of variable speed
drives including Insulated Gate Bipolar Transistor
(IGBT) type inverters.
