1 INTRODUCTION
1Introduction
1.1 Product description
TRAX™ is a unique testing instrument designed to
accomplish routine and advances diagnostics on
power, distribution and instrument transformers as
well as on many other substation components.
A wide range of AC DC current and voltage sources
together with high precision metering instrumen-
tation allow TRAX to be used in a wide range of
applications such as resistance, ratio, excitation,
impedance and primary measurements of power
system components.
TRAX is a unique test system for testing power
transformers, CTs, VTs, and a variety of other power
components. TRAX is capable of providing up to
800 A and 2200 V (up to 2000 A and 12000 V with
optional accessories) with a frequency range of
5-505 Hz (1-505 for insulation testing) and can be
controlled via integrated touch-screen or an external
computer device with a web browser. The compact
design weighs in at only 26 kg (TRAX220) and can be
shipped in its transportation case within the limits of
check-in luggage (< 32 kg).
1.2 Features and benefits
▪Multi-function system for transformer/substation
testing
▪Flexible AC / DC current and voltage sources for a
variety of tests.
▪State of the art measurement methods for advanced
diagnostic testing
▪Variable output frequency for accurate
measurements in high interference environments
▪Compact and lightweight
User interface
TRAX user interface architecture is based on a number
of individual test setups/”instruments”, in this manual
called “Apps”, where only the necessary functionality
is displayed by default. All Apps are “ready to go” in
manual test mode without doing any specific settings.
Just select the amplitude of the test signal and press
start/play. If you prefer guidance from TRAX on how
to perform the measurement, enter the configuration
and TRAX will provide connection diagrams and
a table with the order of measurements. And if a
specific non-standardized measurement is needed, the
“Manual Control” instrument can be used to gener-
ate any voltage or current test signal and measure the
necessary parameters.
All results can be stored and reported as a specific
report containing test object information and all tests
or as data to be imported in e.g. Excel. When testing
a certain substation component, e.g. a power trans-
former, all measurements from different Apps can be
collected in one report/file. It is also possible to use
a former measurement as a template for a new test
session.

Warning and Caution Notices
Warning and caution notices are used throughout
this manual where applicable and should be strictly
observed. These notices appear in the format shown
below and are defined as follows:
Warning
Warning, as used in this manual, is defined as
a condition or practice which could result in
personal injury or loss of life.
Caution
Caution, as used in this manual, is defined as
a condition or practice which could result in
damage to or destruction of the equipment or
apparatus under test.
Open ground detection
1. The unit has an open ground detection circuit
which gives alarm if the mains outlet ground
is missing or different from the station/test
specimen ground. The alarm can be configured
by the user to give an alarm only or actually lock
the unit and prohibit any test signal generation.
2. The mains outlet must have a PE, protective
earth (ground) connected to station ground.
Normally mains outlet PE is connected to station
ground. If that is not the case there are two
alternatives:
▪In compliance with local safety regulations
and permits, use an isolation transformer
where the secondary side Earth/Ground is
to be connected to station ground using a
separate ground cable (not via TRAX unit!)
▪In compliance with local safety regulations
and permits, use a temporary grounding
connection by connecting mains outlet
ground with station ground.
Instrument safety
1. This instrument operates from a single-phase
power source. It has two-pole terminal with
ground connector and requires a two-pole, 16A,
three-terminal, voltage and ground type con-
nector. The voltage of the power source must
be within the following rated operating voltage:
100-240 V ± 10 %, 47 / 63 Hz.
2. Before making connection to the power source,
determine that the instrument rating matches
the voltage of the power source and has a suita-
ble two-pole terminal with ground connector.

2 SAFETY
3. The power input plug must be inserted only
into a mating receptacle with a ground contact.
Do not bypass the grounding connection. Any
interruption of the grounding connection can
create an electric shock hazard. Determine that
the receptacle is properly wired before inserting
the plug.
2.2 Safety instructions
1. It is not possible to eliminate all potential
hazards from, and in using, electrical test
equipment. For this reason, every effort has
been made to point out in this instruction
manual the proper procedures and precautions
to be followed by the user in operating this
equipment and to mark the equipment itself
with precautionary warnings where appropriate.
It is not possible to foresee every hazard which
may occur in the various applications of this
equipment. It is therefore essential that the user,
in addition to following the safety rules in this
manual, also carefully consider all safety aspects
of the test before proceeding.
2. The test set and the specimen to which it is
connected are a possible source of high-voltage
electrical energy and all persons making or
assisting in tests must use all safety practice
precautions to prevent contact with energized
parts of the test equipment and related circuits.
3. Persons actually engaged in the test must stand
clear of all parts of the complete high-voltage
circuit, including all connections, unless the
test set is de-energized and all parts of the
test circuit are grounded. Persons not directly
involved with the work must be kept away from
test activities by suitable barriers, barricades, or
warnings.
4. Treat all terminals of high-voltage power
equipment as a potential electric shock hazard.
There is always the potential of voltages being
induced at these terminals because of proximity
to energized high-voltage lines or equipment.
5. Always ground connection points of the test
specimen before connecting any leads from the
test set. Whenever possible, always keep one
side of the test specimen grounded at all times.
Always use a safety ground stick to ground any
high-voltage conductor.
6. The ground connection on the test set must
be the first made and the last removed. Any
interruption of the grounding connection can
create an electric shock hazard.
7. Make sure that the instrument is properly
grounded, both through its AC power cord and
through the ground connector. The AC power
cord is the disconnecting device.
8. Always disconnect test leads from test specimen
before attempting to disconnect them at the
test set.

9. High-voltage discharges and other sources of
strong electric or magnetic fields may interfere
with the proper functioning of heart pacemak-
ers. Persons with heart pacemakers should
obtain expert advice on the possible risks before
operating this equipment or being close to the
equipment during operation.
10. All persons making or assisting in tests must
use all practical safety precautions to prevent
contact with energized parts of the test equip-
ment and related circuits. Also follow all local
and company safety requirements. Persons
actually engaged in the test must stand clear of
all parts of the complete high- voltage circuit,
including all connections, unless the test set is
de-energized and all parts of the test circuit are
grounded. Persons not directly involved with the
work must be kept away from test activities by
suitable barriers, barricades, or warnings.
11. Safety is the responsibility of the user.
12. Misuse of this high-voltage equipment can be
extremely dangerous.
13. The purpose of this equipment is limited to use
as described in this manual. Do not use the
equipment or its accessories with any device
other than specifically described.
14. Before making any connections, make sure that
the instrument is de-energized and that all parts
of the test circuit are properly grounded.
15. Never connect more than one output at the
time. All outputs are energized by the same
amplifier and therefore all outputs are energized
simultaneously.
16. Operation is prohibited in rain or snow.
17. Do not use the test set in an explosive
atmosphere.
18. A qualified operator should be in attendance
at all times while the test equipment is in
operation.
19. Observe all safety warnings marked on the
equipment.
20. Corrective maintenance must only be performed
by qualified personnel who are familiar with the
design and operation of the test set and the
hazards involved.
Maintenance
1. DISCONNECT the MAINS plug before any
cleaning or maintenance.
2. Maintenance should be performed only by
qualified personnel familiar with the hazards
involved with high-voltage test equipment.
3. Read and understand Safety in the User Manual
before performing any service.
4. Routine maintenance is all that is required for
these test sets. The cables and connector panel
should be inspected frequently to be sure all
connections are tight and all ground connec-
tions intact.
5. The appearance of the test set can be main-
tained by occasional cleaning of the case,
panel and cable assemblies. The outside of the
carrying case can be cleaned with detergent and
water. Dry with a clean, dry cloth. The control
panel can be cleaned with a cloth dampened
with detergent and water. Do not allow water
to penetrate panel holes, because damage to
components on the underside may occur. A
household all-purpose spray cleaner can be used

4 BASIC OPERATING DESCRIPTION
4Basic operating description
4.1 General
TRAX measurements are collected together in tests
and test sessions. A test is often containing several
individual measurements and a TRAX test ses-
sion / file / report often contains several tests performed
with different apps .
Manual and configured tests
Manual Control
Manual tests can be done by using Manual Control
where you define exactly what generator to use,
type of test signal, how results are measured and
how parameters are calculated. This gives unlimited
possibilities to perform almost any AC or DC test on
any electrical component within the limits of TRAX
generating capabilities.
Results from Manual Control measurements for a
certain setup are collected in a result table. If the test
setup is modified due to change of measurement
channels and/or calculated parameters, the new
results are collected in a new test/results table.
Manual test
It is also possible to use TRAX as a manual standard
instrument. This operation mode is defined as
“Manual Test / No configuration” and is available
in all the transformer testing apps. Compared to
Manual Control, this operation mode is locked to a
certain application. As an example, winding resistance
measurements in manual mode is limited to using any
of the three DC current generators and one or two
DC measurement inputs.
Results from Manual Test measurements for a certain
setup are collected in a results table. If the test setup
is changed by e.g. changing from single to dual
channels (simultaneous winding magnetization)
winding resistance, the new results are collected in a
new test / result table.
Configured test
Configured tests are defined by entering information
about the test object, as is the case of vector group
and configuration of a power transformer, if there is
a tap-changer or not and if so on what winding and
how many taps. From that the TRAX app is mastering
the test and you have to perform the test following
the connections described by the unit to get the
automatic assessment of the test.
Also here the app measures one setup at a time.
As an example, if the test object is a three-winding
transformer, TTR measurements may be performed for
three setups, HV-LV, HV-tertiary and LV-tertiary. Each
of these is done as a separate test with a separate test
table, collected together in the same test session.
Test object information
(nameplate)
Test object / nameplate information must be entered
for any configured test and will be part of the test
report. The mandatory information needed for a
certain app is asked for and added to the report. The
next app will have the same information automatically
but may need some additional information to be
added. After all tests you can go to the report and
add any information that is still missing.
Create a test session in advance
If a test session needs to be defined before the test is
actually performed, the workflow is the following:
1] Open the first app and define the test object,
define parameters such as: transformer vec-
tor group.
2] Name and save (the empty) test.
3] Go to the report and fill in all necessary in-
formation for the test object and all planned
tests.
4] Open the next app to create a test table
5] Save and go to the next app. Continue as
above for all desired apps.
6] Finally check the report once again to see
that all the needed data is entered and that
all planned tests are there.
7] Confirm/save and close.

3] Save and go to the next app. Continue as
above for all desired apps.
Use measurement as template
If a new test object is very similar to an already
existing test object, the old test session can be used
as template for the new test. By selecting “Load
template” in the home view, the old test will open
with a new date and no results. By copying the test
under a new name it will be stored and can be used
as template with any necessary changes.

Function
▪Auto: TRAX will create a file directly
when the first (new) app is opened and
ask for name and location for saving.
After this, every measurement and/or
change will be automatically saved.
▪Ask: Upon closing an app or a test
session without manual saving, TRAX
checks if anything has changed in the
test or session and if so, will ask the user
to save changes or not
▪Never / Manual: The user decide when
and what to save manually. TRAX will
not give any save reminder messages
(“multimeter mode”).
Note: Even in manual (“never”) save
mode, TRAX will collect tests in a
“temporary” report/file which makes
it possible to save all or some of the
collected results
