protective ground with no measurable
voltage potential existing between these
ground systems. If a voltage potential
is found between the ground systems
please consult local safety regulations.
1.3 Precaution level – WARNING
Here are the general precautions for level Warning. You must also read and follow the additional
safety precautions in each appropriate section of the
manual..
WARNING
All current units used must also be connected to the control unit. Otherwise the
current unit might be damaged.
WARNING
Always use a grounded mains cable to
connect the control unit to the mains.
Always ground Oden AT using a separate
ground cable
WARNING
The current output terminals and connecting points can be hot after generation of high current.
WARNING
Never switch between the 30 and 60 V
settings when Oden AT is generating.
WARNING
When loading Oden AT on a carriage. To
prevent tip-over, the current units must
be loaded onto the carriage from bottom
up.
WARNING
The carriage is primarily intended for
transportation but may also be used
when testing. The carriage must then
be secured to prevent tip over. It should
withstand a horizontal force of 250 N (N
= Newton, approx. 56 lbs of force) in any
direction applied anywhere to the equipment.
If securing is not possible stack the units
on a flat surface that can support the
load of the units. Make sure that the
stack will withstand a horizontal force of
250 N in any direction applied anywhere
to the equipment.
O d e n A T
1 S a f e t y p r e c a u t i o n s
WARNING
The steel brackets mounted on the carriage are only intended for keeping the
Oden AT units in place during transportation. They are not dimensioned to carr y
the weight of a current unit. A current
unit should always rest either on the
loading pallet or ontop of another current
unit.
WARNING
Never try to service Oden AT yourself. If
you open the casings of the current units
or control unit you may be exposed to
dangerously high voltages.
1.3 Precaution level – Important
Here are the general precautions for level Important.

2 Introduction
2.1 General
Oden AT is intended for use in high-voltage substations and industrial environments, for laboratories
and testing purposes. Oden AT consists of a control
unit equipped with a control panel and can be connected to one, two or three current units mounted
on a carriage. All units are portable and easy to
assemble and connect. Assembly and connection are
explained in chapter 6 ”How to install Oden AT”.
Since Oden AT can incorporate up to three current
units, which can be connected to each other in series
or in parallel,
number of current/voltage combinations. Oden AT is
available in models for 240 V and 400 V mains voltages. There is also a model for operation on 480 V
60 Hz only.
Oden AT is designed to generate short-duration
current, and is protected from overheating. Under
special circumstances, Oden
21,900 amperes.
The current units come in three models: type S, type
H and type X. Each current unit contains a number
of toroidal transformers whose common secondary
side consists of a busbar connected to the HIGH I
output.
For data, see chapter 11 ”Specifications”.
A current unit of type X has, in addition to its
regular high-current output, a low-current output
(0-30V/60V) consisting of two extra windings that
each can provide 30

can be connected either in series or in parallel to the
0-30V/60V output, providing either a 30 V or a 60
V output. For data, see chapter 11 ”Specifications”.
The control unit controls the current output (generation) from the current units and is equipped with
sophisticated measurement facilities.
is first generated for a load, the control unit can
sense the phase angle and adapt subsequent generation operations so that they all start at the current’s
zero-cross-over points. This ensures minimized DC
offset in connection with starting.
When current
Current can be generated in many ways:
• Continuously.
• During a preset maximum time.
• As long as you press a button.
• Until an external signal activates the stop input.
• At a lower current (I/30) to avoid unneccesary
heating of the object being tested while the current is being adjusted.
In pulses (both pulse duration and between-pulse
•
pause are user-definable).
The measurement section contains/provides (among other things):
• Timer.
• Digital ammeter (true RMS).

percentages of nominal values.
Fast-acting hold function. Measured values can
•
be frozen in response to a signal arriving at the
stop input and/or when the current is interrupted.
In addition to its normal working mode, there are
special Oden
AT settings supporting the following
types of testing:
• Microhm measurement (DC resistance is calculated).
•
Testing of direct acting automatic reclosers.
• Testing of sectionalizers.
2.2 Fields of application
Oden AT is primarily intended for:
• Testing of protective relay equipment (primary
injection testing).
Testing of breakers with overcurrent tripping.
•
• Conducting ratio tests on current transformers.
• Conducting polarity tests on current transform
ers.
Other fields of application include:
Tests requiring high currents.
•
• Measuring the resistance of breakers with normal
operating current.
Testing direct-acting automatic reclosers.
•
• Testing sectionalizers.
• Testing ground grids.
-
Even though Oden AT features outstanding versatil
ity, it is very easy to use because:
• You can start generation whenever desired.
• You can repeat a measurement by simply pressing a button. It is not necessary to clear the
display first.
You can save different settings for Oden AT in
•
ten different memories.

2.3 Reservations
When set at maximum current, Oden AT is designed
only for temporary (short-duration) current generation. Do not use Oden AT for long-term generation
at full current. See the product specifications in
chapter 11.

MEMORY
You can save your regular Oden AT settings in
this menu option. Moreover you can, for example,
prepare settings in advance and save them so that
they can be recalled whenever desired. Oden AT has
ten memories numbered 0-9 where you can save settings. The memories retain their contents even when
power to the Oden AT is turned off.
When you start Oden AT, the settings saved in
memory number 0 are loaded automatically. This
means that if you want a specific set of settings to
be used the next time you turn Oden AT on, you can
save them in memory 0 before turning Oden AT off.
There is one additional memory called the standard
memory in which the factory settings are kept, these
factory settings cannot be changed.

6 How to install Oden AT
6.1 Safety
DANGER
When you are changing the connections
make sure that current not can be generated accidently. Disconnect the mains
supply or switch the miniature breaker F2
to the 0-position.
WARNING
The current output terminals and connecting points can be hot after generation of high current.
All current units used must also be connected to the control unit. Otherwise the
current unit might be damaged.
Do not connect two or more ODEN AT
systems in parallel or series. This can
damage ODEN AT.
6.2 Loading Oden AT onto a carriage
The components of Oden AT (i.e. the control unit
and the current units) can be mounted on a carriage
for easy transportation. The carriage also serves as
a platform and helps to raise the control unit to a
comfortable working position
WARNING
To prevent tip-over, the current units must
be loaded onto the carriage from bottom
up.
The carriage is primarily intended for
transportation but may also be used
when testing. The carriage must then be
secured to prevent tip over. It should
withstand a horizontal force of 250 N
(N = Newton, approx. 56 lbs of force)
in any direction applied anywhere o the
equipment.
If securing is not possible stack the units
on a flat surface that can support the
load of the units. Make sure that the
stack will withstand a horizontal force of
250 N in any direction applied anywhere
to the equipment.
The steel brackets mounted on the carriage are only intended for keeping the
Oden AT units in place during transportation. They are not dimensioned to carr y
the weight of a current unit. A current unit
should always rest either on the loading
pallet or ontop of another current unit.
Place the first current unit on the bottom loading
pallet of the carriage. Make sure that the current unit
Fig 6.1 Different positions for the Oden AT carriage. Note, in working position the carriage must be secured to prevent tip
over. Secure it to a suitable object e.g. a pole or a table.

Place the next current unit on top of the first. Make
sure that it too is held in place by the brackets. The
control unit should be mounted last.
When the carriage is in the working position the
control unit can be mounted on the uppermost pair
of brackets for easy access to the controls.
When the
carriage is used for transportation or is placed in the
resting position, the control unit should be placed
ontop of the uppermost current unit to ensure stability. See fig 6.1

• Do not connect units that are of different types to
each other. Only connect type S units to type S
units, type H to type H etc.
•
When using several current units of type X, the
switch 0-30V/60V must be set in the same position on all currentunits.

Always use a grounded mains cable to
connect the control unit to the mains,
and in addition you must connect a separate ground cable. Connect the control
unit to ground as described in fig. 6.7.

6.10 Mains power supply
Mains voltage
ODEN AT is designed either for 240 V, 400 V
or 480 V. The 480 V version is for 60 Hz only.
ODEN AT by itself is a single-phase equipment but
can of course be connected between two phases in a
3 phase system.
There is also a 400 V / 240 V version available. It
is a 400 V version that also can be supplied from
240 V single-phase standard mains outlet. Please
note that it can only be used on a 400 V system having a neutral.
outlet, the mains supply fuse normally is rated 10 A
or 16 A. This will limit the highest output current
but it is still possible to get several kA for a short
time with a slow 16 A fuse. No-load output voltage
at 240 V supply is 60% of values specified in the
Voltage – Current diagrams. Article no is BH-90120
and includes a mains adapter box.
Input Current
The input current is directly dependent on the output
current and the ratio is stated for each configuration
in the operators’ guide. It can also be calculated for
a 400 V or a 480 V 60 Hz version as:
Output current x Open circuit voltage
and for a 240 V version as:
Output current x Open circuit voltage
Calculated or specified values refer to worst case,
i. e. when current setting is on its maximum. If
settings only need to be at 50% to get the output current, input current is 50% of value above.

6.12 How to arrange the cable sets
Minimising impedance in cables
Just increasing cross-section area helps only to a
certain extent. When resistance is low, the major
part of the impedance is caused by the reactance.
Minimising the magnetic flux will reduce the reactance:
• Best is if a cable from a current unit terminal can
be twisted together with a cable from the other
terminal on the same curr
ent unit. This guarantee opposite current with same value which will
almost neutralise the magnetic flux.
• f cables not can be twisted, keep cables with
same current direction away from each other as
much as possible
Avoid loops or “windows”.
•
Current unit with twisted 2 pairs Multi-Cable Set
It is sometimes not possible or practical to twist the
cables. However any action to keep cables with opposite current direction close together and to minimise loops helps. If the distances to the test object
terminals are different it is better to use cables with
different lengths in order to avoid loops.

6.13 How To Arrange Bars
Copper-bars are in many cases a better solution than
cables at high currents and short distances and at
long load times. Bars must be specially designed for
the actual test objects and in general this work must
be the users responsibility. Here are some guidelines:
• Proper cross section area. Not less than 500 mm
- 1000 mm2 (depends on the actual current). Take
eventual heating into consideration.
• As close to the bar as possible (preferably maximum 1 mm) there should be another bar carrying
the same amount of current in the opposite direc-

tion.
if this arrangement slightly increases the length,
it still is a gain because impedance due to magnetic flux is a bigger problem than the resistance.
• Do not use bars thicker than 10 mm and arrange
the bars with their flat sides close together. The
reason is that the magnetic flux (and the reactance) will be more ef

opposite direction.
fective neutralised if the
Make parallel connections between the terminals of
the current units. Contact must be good, preferably
use bars. Connect the cable set between the bars and
the test object.
2
• Loops (windows) that allow magnetic flux must
be avoided).
Joints must have low resistance
•
Example:
Two copper bars have the cross section 10 mm x
50 mm and they are mounted 5 mm from each other
(the flat sides close together). Per meter of this arrangement the impedance is:
90 m at 50 Hz (R = 73 m and X = 54 m)
98 m at 60 Hz (R = 73 m and X = 65 m)
To get equal current from all current units.
When units are connected in parallel care must be
taken that one unit does not supply the major part
of the current. Otherwise its thermal protection can
trip.
Method 1
There should be no parallel connections between
the terminals of the current units. Make sure that the
cable impedance between each current unit and test
object is equal (same number of cables and same
length).
Method 2
If number of cables used can not be evenly divided
by the number of current units.

7.2 Rules of thumb when generating current
When you generate current there are rules which can
be useful to follow:
• To reduce voltage drop, the current cables running to the object being tested should be as short
as possible and have sufficient heavy-gauge
(thick) cross-area.
age drop further by twisting cables of different
polarity together (see fig 6.2), thereby making it
possible to inject higher currents.
• If the object being tested has a low impedance
connect the current units in parallel. Connect
them in series if the object has high impedance.
To avoid unneccesary heating of objects being
•
tested, current can be generated in brief intervals.
It might be best to use manually-controlled (momentary) injection or time-limited injection.
Oden AT, it is also possible to make a coarse
adjustment of the current using the I/30 function
(which uses only 1/30th of the real test current).
• When operating time is measured, the value
of the injected current or applied voltage must
exceed the lowest operating limit by an ample
gin (1.2 - 2 times is the rule of thumb here).

Low currents:
1. Connect the object being tested to a suitable
Oden AT output.
2. Press <ON+TIME>.
3. Adjust the current using the coarse adjustment
buttons or the fine adjustment knob. The value
of the current will be presented on the display.
High currents:
High currents can generate a great deal of heat in
both Oden AT and the object being tested. To avoid
unneccesary heating, you can:
•
Generate current only for brief intervals.
• Use the I/30 function .
Generating briefly
There are two easy ways to generate current for
brief intervals: a) using the <MOM ON>-button or
b) using the limited-time generation function. These
are described in this chapter in section 7.13 “Measuring operating limits”.
Using I/30 function
Connect Oden AT properly to the object being
1.
tested. See chapter 6 ”How to install and connect Oden
AT”.
2. Activate the I/30 function.
3. Press <ON+TIME>. The current is displayed
as ”XXXX/30”. XXXX represents the value
the current will have when the I/30-function is
released.
Adjust the current using the coarse adjustment

buttons or the fine adjustment knob. The value
of the current will be presented on the display.
5. Shut off the current using the <OFF> button.
6. Deactivate the I/30 function.
7. Activate the HOLD function by pressing
<HOLD>.
8.
Press the <MOM ON>-button briefly.
9. Read the current presented on the display.
10. Use the <FINE> knob for fine adjustment of the
current.

7.6 Getting maximum current from Oden AT
Maximum output current is limited by the following:
• Impedance of the object being tested.
• Impedance of the current cables.
• Mains supply.
• Voltage drop in mains cables and other cables.
• Oden AT’s internal impedance
To obtain maximum current from Oden AT proceed
as follows:
•
Connect two or three current units together.
• If the object being tested has high impedance,
connect the current units in series.
If the object being tested has low impedance,
•
connect the current units in parallel.
Use short, heavy-gauge (thick) cables and
•
twisted cables, see fig 6.2.
7.7 Improving the resolution of current settings
If you want to improve the accuracy of current settings, you can:
• Use a voltage that is as low as possible by (for
example): a) not connecting the current units
in series, b) using the high-current output even
when low currents are to be generated, or b)
connecting the low-current output for the lowest
voltage (0-30
current unit.
• Increase the impedance in the circuit, for instance use longer
cables.

connected at the right places etc.).

7.8 Generating pulse trains
You can set Oden AT to generate a pulse-train (intermittent current generation at regular intervals, i.e.
pulse-pause-pulse-pause etc.). This will continue until you shut off generation, until a preset maximum
time (MAX TIME) is reached or until the condition
at the STOP INPUT is met.

7.13 Measuring operating limits
There are three ways to measure operating limits:
• Normal generation. Used when there is little risk
for undesirable heating in the object under test.
•
Manually-controlled momentary injection.
• Limited-time generation. Used when you do not
want to expose the object under test to needless
heating.
Method 1: Normal injection; gradually increase in current.
In this method current is sent out continuously.
The current is gradually increased until the object
being tested operates. When this happens a) the
LATCHED lamp lights up, b) the current value is
frozen on the display and c) the current to the object
is interrupted.
When you are testing protective relay equipment
you can, as a next step, reduce the current and freeze
the displayed value to obtain information about the
drop-out function.
1.
Basic settings:
OPERATE: OFF.
CURRENT ADJUST: Lower than the tripping/
operating limit.
HOLD function:
AUTO OFF: STOP INPUT.
2. • For proteive relay equipment:
Set the stop condition to (for example):
• For breakers:
Set the stop condition to INT.
3. Start generation by pressing <ON+TIME>.
ON.
7. Start generation by pressing <ON+TIME> and
turn up the current until the protective relay
equipment operates (pick-up).
8. Turn down the current until drop-out occurs.
The value frozen when drop-out occurred is now
presented on the display
.
For protective relay equipment you can simplify the
procedure by testing both the pick-up and drop-out
functions with a single current generation operation.
This can be accomplished as follows:
Basic settings:
1.
OPERATE: OFF
CURRENT ADJUST: Lower than the tripping/
operating limit
HOLD function:
ON
AUTO OFF: Turn off the AUTO OFF
function (neither the STOP
INPUT nor the MAX TIME
lamp will be lit)
2. Select the stop condition:
3. Start current generation.
4. Increase the current until the protective relay
equipment operates (pick-up).
5.
Read the pick-up function value from the display
.
6. Press <RESET>.
7. Turn down the current until the protective relay
equipment drops out. You can now on the dis
play read the value that was frozen when dropout occurred.
Method 2: Manually controlled momentary injection
4. Increase the current until operation occurs.
5. The value frozen when operation occurred is
now presented on the display.
Note! If the impedance of the object under test
changes during operation, you should use
the maximum cur
rent value during the
operation as pick-up value. Press <ESC>button to get the maximum value, see
section 3.1. MENU block.
The following apply only when testing protective
relay equipment:
6.
In order to measure the drop-out function,
change the stop condition to (for example):
Here, current is sent out as long as you hold down
the <MOM ON> button. This method is useful when
you do not want to expose the object being tested to
unneccesary heat.
1. Basic settings:
OPERATE: OFF
CURRENT ADJUST: Close to the operating limit
HOLD function: ON
AUTO OFF: STOP INPUT
2. • Foprotective relay equipment:

3. Press <MOM ON> briefly. Note, however, that
current must be sent out for a period longer than
the operating time.
4. Read the current from the display.
5. Change the current setting somewhat.
6. Repeat, starting at step 3 above, until you find
the lowest current that provides operation.
Method 3: Limited-time generation
Here, current is sent out for a limited period of time
and interrupted when a present maximum time
(MAX TIME) is reached. This method is useful
when you do not want to expose the object being
tested to unneccesary heat. Section 7.4 “Setting
times for limited-time generation (MAX TIME)” in
this chapter explains how to set MAX TIME.
1. Basic settings:
OPERATE: OFF
CURRENT ADJUST: Close to the tripping/opera
ting limit
HOLD function :
AUTO OFF: Specify MAX TIME
2. • For protective relay equipment:
Set the stop condition to (for example):
ON
(choose a generation time
that is longer than the
operating time) and also
specify STOP INPUT
7.14 Measuring tripping/operation times
Here, generation continues until the protective relay
equipment operates or the breaker trips. To avoid
unneccesary heating or operation of the object being
tested, the I/30-function can be used (see section 7.3
”Setting the desired current” in this chapter) while
the current is being adjusted.
1. Basic settings:

CURRENT ADJUST: Lower than the operating
limit.

be measured. The current must exceed the oper-
ating limit by an ample mar

time.
5. Change the current setting somewhat and repeat,
starting at step 4 above, until you find the lowest
current that provides instantaneous pick-up.
When you test the instantaneous trip time make
the following settings. Use the I/30 function (described in section 7.3 “Setting the desired current”

7.16 Selecting Oden AT
configuration and current cables
Introduction
Different applications have various requirements on
current and load time and the test objects have different impedance. The ODEN AT concept has three
types of current units and they can be connected in
series or in parallel. So there are good possibilities
to find a configuration that meet your requirements.
Examples of different applications:
• Up to 5 - 7 kA through 5 m current cables. Applications:
• > 10 kA through a low-impedance test object
placed close to ODEN AT.
Applications:
ers and joints.
• More than 100 V to push currents up to 400 A.
Applications: Primary injection through cables or
lines.
Continuous current generation.
•
Up to 2.5 kA
Up to 3.8 kA if test object has low impedance
and bars are used as current conductors.
Available systems
• Any system must have a control unit
• There can be 1, 2 or 3 current units in a system
• There are 3 different types of current units: S
(Standard), X (Extra output) and H (High current)
Test of outdoor apparatus.
Test of Low Voltage Circuit Break-
through 5-m current cables.
Test circuit impedance limits the current
The test circuit impedance Z consists of current cable
impedance and impedance of the test object. According to Ohms law I x Z volt is required to push current
I through the impedance. If voltage at ODEN AT
terminals is less, current will be lower than desired.
Note! Voltage is required to get current through
the impedance and you need to know the
impedance of the test cir
Please not only look at the maximum
rated current of the ODEN AT configuration. Y
ou must also check that the available voltage at ODEN AT’s output terminals (see chapter 11 Specifications) is
sufficient
to push current through the test
circuit.
The cur
rent capability is dependent on
the load time. You must also check in
the load time - current diagram that the
system can generate the desired current
for the required load time.

Altogether there are 18 different ODEN AT systems.
Furthermore, the current units can be connected in
parallel or series. In total there are 46 dif
ferent configurations available. Their specifications are present
in the chapter “Specification”.
The system designation indicates the number and
type of current units.

7.17 How to succeed in selecting a suitable ODEN AT system
Please follow the procedure below. It implies that
you first choose configuration and then suitable
current cables. At the end of this chapter you will
find two forms (Form 1 and Form 2) useful for the
procedure. Form 2.is for cases where you must use
a certain cable set (length, cross section or weight
restrictions).
Required information
•
Application
• Desired Current
• Desired load time
• Distance to the test object
• Is it possible to twist current cables
• Impedance and type of test object
• Mains voltage supply and its current capability
Distance to the test object
• Use as short cables as possible
Length (impedance) has a direct impact on maximum possible current. There is no reason to burn
power in unnecessarily long cables.
Impedance of the test object
Knowledge saves you from surprises
• Test object impedance has most impact at higher
currents and when current cables are short.
•
Test object impedance is less important when
cable set is 5 meters or longer and only consists
of one or two cables each side.
impedance is the major part of the test circuit
impedance.
• Test object impedance can be measured. Inject an
AC current, measure voltage drop directly across
the object. Divide voltage by the current to get
the impedance (mΩ = V / kA).
If possible, current magnitude should be the
same as when testing the object. Some test objects saturate at high currents and measurement
at low currents will give a too high impedance
value.
Note! Do not use a DC - microhmmeter for
measuring. Y
ou will get a too low value
since the reactive part is excluded.
• Test object impedance can be estimated from
experience. Some examples:
Then cable set
a) Low Voltage air breaker rated 4 kA:
0.09 - 0.2 mΩ
b) Low Voltage circuit breaker rated 630 A:
0.3 - 1mΩ
c) Outdoor breaker pole or disconnector:
0.2 - 0.5 mΩ
In general test objects rated for higher currents have
lower impedance
Regarding current transformers, the impedance in
the secondary circuit has a direct impact on the impedance. Shunting secondary circuits not included
in the test reduces but some users dislike to do that.
For out-door current transformers current cable
impedance is usually the problem, not impedance of

5. Select current cables / conductors
You know the length. Select from tables in chapter
3, ”Current cables and conductors”.
•
Impedance may not exceed maximum allowed
value. It should be as low as possible but cable
set should not be unnecessarily clumsy or heavy
• Impedance can be reduced by:
a) twisting cables since it reduces the reactance.
Important!
b) using sets with more cables
c) using several cable sets in parallel.
This is
especially useful when current units are used in
parallel.
• At continuous or long term load:
Check that the current per cable not will be too

high (a 120 mm
cable can withstand 350 A
continuously). If so, use a set with more cables in
parallel.
• Weight. Overhead test object must be able to
carry the weight of the cable set. Divide weight
by 2 to get load at one side of the test object or
check if the cables can be supported by other
method.

high currents and short distances.

6 Check input current
Again, to avoid surprises. ODEN
AT is like a
transformer, high output power requires high input
current. Your mains supply must be able to supply
the current.
See also Chapter 6, section 6.10 "Mains power supply” and Chapter 1
1, ”Specifications” for informa-
tion how to calculate.
Current calculation example
Q: Output voltage is lower than test circuit imped-
ance x current? What is the highest possible current I can get?
A: Draw a line in the voltage versus current diagram
representing the impedance. The highest possible
current is where impedance line crosses the voltage graph. See diagram below
.

If distances to test object terminals are different,
•
using a set with different cable lengths can reduce impedance.
This also makes twisting easier
5. Rules of thumb
a) Distance max. 1 meter
, current 5 - 15 kA
(For example Low Voltage Circuit Breaker testing)
Minimise cable impedance. Weight is a minor prob-
lem. Use cable set with many cables in parallel
or bars.
b) Distance 5 meters or more, current max 3 kA
and
time max. 10 seconds:
(For instance at outdoors Current
Transformer
testing)
Since current is moderate and load time is short, it is
possible to use a cable set that is not too clumsy
.
One or two cables in parallel each side is sufficient in many cases, especially if it is possible to
twist the cables.
c) Distance 5 meters or more and current > 3 kA:
(for instance outdoor Current
Transformer test-
ing)
Low impedance must be given highest priority in
order to get the desired current.
This means many
cables in parallel. Unfortunately it is unavoidable

8 Application examples
This chapter explanis step-by-step how some specific objects are tested. The following are discussed:
• Testing a low-voltage circuit breaker
• Testing the turns ratio of a current transformer
• Testing the polarity of a current transformer
• Measuring the resistances of breakers and electri
cal connections (microhmmeter testing)
• Testing a direct acting recloser
• Testing a sectionalizer
• Testing a ground grid
8.1 Testing a low-voltage breaker
The following sections explain how to test a lowvoltage breaker. Start by measuring the overcurrent
stage’s tripping limit and the tripping time. Then
measure the tripping limit and tripping time for the
instantaneous unit.
-
Measuring the tripping limit (normal generation):
Current is generated continuously and gradually
increased until the breaker trips.
trips the current shown on the display is frozen
and the current is interrupted. When current first is
generated for a load (while the current is being set),
Oden AT adapts itself so that all subsequent generation operations start at the current’s zero-cross-over
points. This ensures minimized transient DC offset
when the injection is initiated.
1. Basic settings:
OPERATE: OFF
CURRENT ADJUST: Lower than the tripping
limit
HOLD function:
AUTO OFF: STOP INPUT
2. Set the stop condition to INT.
ON
When the breaker
3. Start generation by pressing <ON+TIME>.
4. Increase the current until tripping occurs (the
LATCHED lamp lights up).
5. The current value frozen when tripping occurred
can now be read from the display.
Note: You can read out the highest current
value during an operation by pr
<ESC> repeatedly until "max" appears
after a current value. This value should
be used for test objects whose impedance changes during the operation.
Measuring the tripping time:
1.
Set the current to an ample margin above the
tripping limit. The procedure is described in
section 7.3. Use the I/30 function (step 2 to 6 in
section 7.3) if you want to set the current without operating the breaker
Note: Disable the INT-function when you are
using I/30.

4.
Read the time and the current presented on the
display.
Instantaneous trip unit measurement:
When you test the instantaneous pick-up you can
provide a manually-controlled momentary current
injection by pressing the <MOM ON> button.
This
permits you to find the instantaneous trip unit’s lowest operating current without tripping the overcurrent stage.
1. Basic settings:
OPERATE: OFF
CURRENT ADJUST: Close to the tripping limit
HOLD function: ON
2. Set the stop condition to INT.
8.2 Testing the ratio of a current transformer
This test determines whether or not a current transformer has the correct ratio. During the test, current
is injected into the primary side of the current trans-
, and the current in each secondary winding is

3. Select a suitable current setting.
4. Press <MOM ON> briefly. The time throughout
which current is generated must be shorter than
the overcurrent stage’

also use limited-time current generation (MAX
TIME). See section 7.13 "Measuring operating
limits".
5. Change the current setting somewhat and repeat
from step 3 above until you find the lowest current that provides tripping of the instantaneous
trip unit.
In order to measure the instantaneous trip time
proceed as follows:
1.
Increase the current to an ample margin above
the tripping level.

that is to be tested. Make certain that this winding is not connected to any other circuit.
4.
Activate A-METER 2 in the <V/A METER> menu
option under the "A-METER 2" menu heading.
5. Select "A-METER 2 NOM I" and set the nominal
secondary current for the current transformer
.
You might, for example, set it to 5 A.
6. Select "A-METER 2 UNIT", and then select
“CT ratio".
7.
Press <ON+TIME>.
8. Set the desired primary current, whereupon both
the primary current and the actual ratio will appear on the display
.
Example:

1000
5000/5.
5.107s
1.00kA 5000/5 A
Note: Another method to measure the ratio be-
tween primary and secondary current is
to set the unit for ammeter 1 to "I1/I2".
Do not however try to combine the two
methods!

also make certain that all local regulations which govern work with high-voltage
equipment are complied with.
WARNING
Before you connect Oden AT to a breaker,
you must make certain that the breaker
is closed and grounded on one side.
WARNING
Do not measure on outdoor High Voltage
Circuit Breakers due to risk for capacitively coupled currents. It could cause
danger and/or damage.

8.7 Testing a ground grid
The best method of testing the integrity of a ground
grid is the High Current Method. An Oden AT
equipped with a current unit of type X is very suitable for this kind of tests. Here is a brief description
of how such tests is conducted with Oden AT.
A current of 300 A is to be injected between one
reference ground electrode (usually the grounding
point for a transformer) and the ground to be tested.
One criterium that must be met before a ground
network can be approved is that at least 50% of the
total current injected between points passes through
the ground network. Moreover the voltage drop
must not exceed 0.1V/meter
Connect the output you intend to use for measurement (the 30
V output on a type X current unit for
example) to the injection points. Then, in addition,
connect the voltmeter input to the injection points.

Problem: Time ”0.000s” is displayed but generation continues.
Possible cause: The stop condition is met but
AUTO OFF is not activated.
Remedy: Press <RESET> if you want the generation time displayed.
Problem: ” ——- A or ——-V” is displayed.
Cause: Because the measurement time was too
short, the HOLD function cannot present any frozen
readings or there was not enough time for a range to
be selected automatically.
Problem: Unexpectively long trip-time
while testing instantaneous trip on a circuit breaker.
Remedy: Increase INT-level or use range or output
with higher current rating.
Remedy: Increase the measurement time or select a
fixed range.
Problem: ”——- OFA or OFV" is displayed.
Cause: The magnitudes of the input signals are too
great for the fixed preset range or the AUTO range
does not have time to function properly for highspeed cycles. (”OF” = Overflow)
Remedy: Carry out a new measurement or select a
fixed range.
Problem: ”AMP2=0A AMP1=0A”is displayed.
Cause: Because the measurement current is 0, no
ratio can be calculated.
Remedy: Generate current.
Problem: ”**** A”is displayed.
Cause: Ammeter cannot present measured values
for the generated current because:
• Current units are of different types.
• Current unit unknown because it is uncalibrated.
Remedy: Connect same type of current units or calibrate the current unit.

10 Calibration
10.1 General
You can calibrate the zero levels (offset) for ammeter 1, ammeter 2 and the voltmeter. The timer
in Oden AT is crystal controlled and requires no
calibration, but can be checked against an external
timer.
The instruments used for calibration should have a
verified high accuracy
The control unit and the current units must be calibrated together
your Oden AT system once a year, but also if a new
current unit is added to your system or if the system
has been exposed to extreme variations in ambient
temperature.
Regarding calibration of the scale factors we recommend that it is done at 2/3 of the measurement range
or at 2/3 of the highest rated current for your Oden
A
T-system (see output specifications in chapter 11).
You can however calibrate at other values. If accuracy at a certain value is important you can calibrate
at this value instead.
. It is recommended that you calibrate
.
10.2 Calibration of offset
The zero-offset for ammeter 1, ammeter 2 and the
voltmeter is calibrated.
1. Make sure that no current units are connected to
the control unit and that the input for ammeter 2
is open.
Short circuit the voltmeter input (i.e. the voltage
2.
should be 0 V).
3. Press the <SYSTEM> button.
4. While simultaneously pressing the but
tons <ESC> and <ENTER>quickly turn the
<CHANGE> knob clockwise until "CALIBRA-
TION" appears on the display. Press <ENTER>
to confirm.
5.
Choose ”Zero-offset” and press <ENTER>.
6.
Calibration of zero-offset is done automatically.

10.7 Resetting to preset (standardized) calibration values
Instead of regular calibration a resetting function
can be activated that will set the calibration values
to a set of preset and standardized values. This will
give an accuracy of about 1%. Resetting can never
replace a regular calibration where accurate and
traceable reference instrument are used, but is a
quick and simple method of solving the problem of
having no calibration values at all. Resetting must
always be followed by a calibration of the zero-offset, which is a part of the regular calibration procedure.
It is possible to combine resetting and calibration;
first perform a reset and then calibrate the ranges for
which required instruments and sources are available.
The ranges that can not be calibrated will then
use the standard calibration values.
O d e n A T
Note: When a reset is performed, ALL settings,
values and parameters will be set to pr
eset default values. This also implies the
settings stored in Oden AT’s memories,
which will be lost if a reset is performed.
Performing a reset
1. Press down the <RESET> button while Oden AT
is switched on.
