Operation & Maintenance Manual
ATL-M001-A2 1
1.0 Installation
1.1 Location
Location of the AUTOTRANSLINEATOR™should be
made with consideration given to accessibility,
ventilation and atmospheric conditions. Sufficient
clearances from walls and other obstructions
should be provided to permit unrestricted opening
of hinged and removable doors, covers and
panels for the purpose of wiring terminations,
inspection, maintenance and testing. Also, proper
ventilation requires at least 6 in. (155mm)
clearance at all ventilation openings. In enclosed
rooms, minimum air circulation of 100 ft3/ min per
kilowatt of transformer loss should be provided.
Installation locations should be free of
contaminants including dust, fertilizer, excessive
moisture, corrosive gases, flammable materials or
chemical fumes. Filtered air may be considered to
reduce maintenance where air born contaminants
are a problem.
Enclosures are designed in accordance with
NEMA and UL standards and can allow for
installation in various environments. Standard
enclosures for the AUTOTRANSLINEATOR™are
NEMA3R and NEMA3R Enhanced.
Where AUTOTRANSLINEATORS™are connected to
lines subject to lightning exposure or other voltage
surges, careful coordination of BIL levels and
protective surge arresters must be made. For
derating factors which apply to installation at high
altitudes, refer to ANSI C57.12.01-1989.
1.2 Inspection
Upon receipt of shipment the
AUTOTRANSLINEATOR™should be inspected for any
damage incurred during shipment. Before
energization an internal inspection should be
conducted with emphasis on loose or broken
connections, damaged or displaced parts, cracked
insulators, dirt or foreign material, or evidence of
moisture.
1.3 Handling
The AUTOTRANSLINEATOR™should be thoroughly
protected against the entrance of dust, rain or
snow when handled outdoors.
When lifting the AUTOTRANSLINEATOR™, the lifting
cables should be held apart by a spreader to avoid
bending the lifting lugs or other parts of the
structure. The AUTOTRANSLINEATOR™may be
skidded or moved on rollers but care must be
taken not to damage the base or tip it over. When
rollers are used under larger units, skids must be
used to distribute the stress over the base.
After the AUTOTRANSLINEATOR™is placed in
permanent position, shipping braces should be
removed and shipping bolts, if present, should be
loosened. Where isolation pads have been
included, the bolt should be loosened until the
spring washer has been relaxed before putting
into service. This will reduce noise resulting from
the AUTOTRANSLINEATOR'S™natural vibration.
1.4 Grounding
Consideration must be given to equipment
grounding (case and core) and must be made in
accordance with all applicable electrical codes.
2.0 Storage
Condensation and moisture absorption must be
prevented during storage. The
AUTOTRANSLINEATOR™must be stored in a warm,
dry location. Ventilation openings should be
covered to keep out dust. If outdoor storage
cannot be avoided, the AUTOTRANSLINEATOR™
must be protected to prevent entrance of water,
moisture and foreign material.
WARNING
Danger! There is the potential of
electric shock whenever working
in or around electrical equipment
such as transformers. Power must
be shut off before any work is
conducted on a transformer.

3.0 Maintenance
WARNING
Internal maintenance must be
performed with a transformer de-
energized, isolated and with the
terminals grounded.
3.1 Periodic Inspection and Maintenance
The AUTOTRANSLINEATOR™has no moving or
active parts and therefore requires only minimal
periodic maintenance when installed in a clean
and well ventilated environment. This should
include:
3.1.1 Visual inspection for evidence of loose
connections, dirt, moisture, rusting,
corrosion, and deterioration of the
insulation, varnish or paint.
Observations should be made for signs
of overheating and overvoltage creeping.
Corrective measures should be taken as
necessary.
3.1.2 For early detection of any developing
hotspots, an infrared scan can be
performed while the
AUTOTRANSLINEATOR™is operating under
its heaviest load condition.
3.1.3 Measuring the current in each of the 3
phases of the capacitor circuit can be a
quick and easy method of determining
the condition of the capacitors. The
capacitors can be assumed to be in good
operating condition when all 3 phases
carry approximately the same amount of
load current. Measurements should be
taken at the input to the capacitor fuse
block and can be done at any loading
condition. If the phase currents are found
to be substantially different, the unit
should be taken offline and serviced by a
qualified technician. This test should be
conducted annually or whenever the unit
seems to be operating in an abnormal
manner.
3.2 Cleaning
Excessive accumulations of dirt on the transformer
windings or insulators and capacitor terminals
should be removed to permit free circulation of air
and to guard against the possibility of insulation
breakdown. Particular attention should be given to
cleaning the top and bottom ends of the winding
assemblies and to cleaning out ventilating ducts.
Windings should be lightly cleaned by the use of a
vacuum cleaner. If necessary a blower or
compressed air may be used but pressure should
not exceed 25 psi. Lead supports, tap changers
and terminal boards, bushings, and other major
insulating surfaces should be brushed or wiped
with a dry cloth. The use of liquid cleaners is not
recommended due to deteriorating effects on most
insulating materials.
3.3 Drying of Core and Coil Assembly
CAUTION
Constant attention during the
drying process is recommended.
When it is necessary to dry a
AUTOTRANSLINEATOR™transformer before
installation or after an extended shutdown under
relatively high humidity conditions, internal and/or
external heating methods can be used. (See
ANSI/IEEE C57.94-1982 for a description of these
methods).
It is important that most of the heated air pass
through the winding ducts and not around the
sides. Good ventilation is essential in order that
condensation not take place in the reactor itself or
inside the case. A sufficient quantity of air should
be used to assure approximately equal inlet and
outlet temperatures.
Air temperature should not exceed 70°C.

4.0 Operation
WARNING
Internal maintenance must be
performed with a transformer de-
energized, isolated and with the
terminals grounded.
Caution: Do not remove covers, panels, or any
enclosure parts while the AUTOTRANSLINEATOR™is
energized.
4.1 Effect of Humidity
While the AUTOTRANSLINEATOR™is energized,
humidity conditions are generally not important
since the heat from the reactor will prevent
condensation. If a shutdown exceeding 24 hours
occurs during a period of high humidity that could
cause condensation within the transformer,
precautions should be taken. Small strip heaters
may be energized in the bottom of the unit to
maintain the temperature of the unit a few degrees
above that of the outside air. If such precautions
are not taken the unit should be inspected for
evidence of moisture and insulation resistance
checked. If necessary, dry as described in
Maintenance section above.
4.2 Loading
AAUTOTRANSLINEATOR™should only be loaded in
accordance with its nameplate rating.
