Preface

CPC 100 User Manual
Preface - 2
Preface
The CPC 100, in conjunction with its accessories or as a stand-alone unit, is a multi-purpose
primary test set for commissioning and maintaining substation equipment. It performs current
transformer (CT), voltage transformer (VT) and power transformer (TR) tests. Furthermore, it is
used for contact and winding resistance testing, polarity checks as well as primary and
secondary protection relay testing.
The various, partly automated tests are defined and parameterized via the front panel control of
a built-in embedded PC.
The functionality scope of the CPC 100 is described in detail in the chapter “Designated Use” of
the CPC 100 Reference Manual available in PDF format on the Primary Test Manager DVD or
the CPC 100 Start Page.
Note: Any other use of the CPC 100 but the one mentioned above is considered improper use,
and will invalidate all customer warranty claims and exempt the manufacturer from any liability
to recourse.
Example of the separation of work area and high-voltage area using different OMICRON
devices:
► Do not enter the high-voltage if the red status light of the CPC 100 is on.
Safety symbols on the device
General
The CPC 100’s outputs and the cables connected to them carry life-hazardous voltage or
current.
► Always obey the five safety rules and follow the detailed safety instructions below.
► Before connecting or disconnecting test objects and/or cables, turn off the CPC 100 by
pressing the POWER ON/OFF switch. Then press the Emergency Stop button.
► Never connect or disconnect a test object while the outputs are active.
► Make sure that a test object’s terminals that are to be connected to the CPC 100 do not carry
any voltage potential. During a test, the only power source for a test object may be the
CPC 100.
► At their output sockets and especially in the cables connected to them, in operation the high-
current outputs 400A DC and 800A AC generate a significant amount of heat (approx.
300W/m at 800A). To prevent burns, use gloves when touching the cables while in
operation or a short while after.
► Do not insert objects (e.g., screwdrivers, etc.) into any input/output socket.
► Never use the test cards Quick and Resistance to measure the resistance of windings with
a high inductance because turning off the DC source results in life-threatening voltage
levels. For this kind of measurement only use either the special winding resistance test card
RWinding or the test card TRTapCheck.
► When measuring the ratio of voltage and power transformers make sure that the test voltage
is connected to the corresponding high-voltage winding, and the voltage of the low-voltage
winding is the one that is measured. Accidentally mixing up the windings can generate life-
threatening voltages within the transformer.
FOR YOUR OWN SAFETY
Always follow the 5 safety rules:
1. Disconnect completely.
2. Secure against re-connection.
3. Verify that the installation is dead.
4. Carry out grounding and short-circuiting.
5. Provide protection against adjacent live
parts.

Preface - 3
► Make sure that when testing a current transformer by feeding a test current into its primary
winding, all secondary windings are shorted. On open secondary windings, life-threatening
voltages can be induced.
► Connect only one CPC 100 output at a time.
► All AC and DC output sockets of the CPC 100 can carry life-hazardous voltage potential and
provide life-hazardous currents. Therefore:
► While connecting cables to the CPC 100 high-voltage or current outputs, or other
conducting parts that are not protected against accidental contact, press the Emergency
Stop button, and keep it pressed as long as an output signal is not absolutely necessary
for the test.
► When connecting to the front panel input/output sockets, use wires with either 4 mm
safety “banana” connectors and plastic housing or, where applicable, with the especially
manufactured counterpart supplied by OMICRON (e.g., for the V2 AC measuring input).
► For the high-voltage and current output connectors on the left-hand side of the test set
(2kV AC, 400A DC and 800A AC, Ext. Booster), only use the specially manufactured
cables supplied by OMICRON (refer to the chapter “Accessories” of the CPC 100
Reference Manual available on the Primary Test Manager DVD or the CPC 100
Start Page).
► One end of the high-voltage cable has a coaxial safety plug that is certified for a voltage
level of 2kV AC. The other end is equipped with a safety banana plug that is insulated
with a shrink tube. When the CPC 100 is switched on, consider this part of the cable a
hazard of electric shock.
► If you do not use the high-current outputs 400A DC or 800A AC, or the high-voltage
output 2kV AC, disconnect any cable that may be plugged in to these sockets.
Note: The 400A DC or 800A AC outputs are not switched off by internal relays. Therefore,
if a test mode is selected that does not use either one of these two outputs, they still
generate current.
► Do not stand right next to or directly underneath a connection point because the clamps may
fall off and touch you.
► The red status light on the CPC 100 front panel indicates hazardous voltage and/or
current levels at the CPC 100 outputs (red light “I” on or flashing). The green status light
indicates that the CPC 100 outputs are not activated.
Note: If none or both status lights are on, the unit might be defective. Contact
OMICRON Support.
► Both of the high-current output sockets on the left-hand side of the test set (400A DC
and 800A AC) usually carry a relatively low-voltage potential. However, in case of an
internal insulation fault these outputs may carry up to 300 V. Consider these outputs life-
hazardous.
► Always lock connectors properly.
► The high-current cables for both the 800A AC and 400A DC outputs are equipped with
connection clamps at one end. If these connection clamps are attached to a test object’s
terminal that is situated above your head, make sure the clamp is securely attached. Due to
the weight of the cables the clamp may become loose and fall down.
► Do not operate the CPC 100 under ambient conditions that exceed the temperature and
humidity limits listed in ”General” on page Technical Data-3.
► Do not operate the CPC 100 in the presence of explosives, gas or vapors.
► If the CPC 100 or any add-on device or accessory does not seem to function properly, do
not use it anymore. If in doubt, contact OMICRON Support. (refer to cover page of this User
Manual).
Grounding
Operating the device without PE and ground connection is life-threatening and not permitted.
► Only operate the CPC 100 with a mains power supply connected to protective earth (PE).
► Make sure that both the PE connection of the power supply and the ground connector of the
CPC 100 have a solid and low-impedance connection to the grounding system on site.
This also applies to all other test devices and accessories in the test setup.
► Make sure that the grounding clamp has a good electrical contact to the grounding system
on site and avoid connecting it to corroded or painted surfaces.
► Make sure that the grounding terminal connections of all grounded devices in use remain
intact during the whole measurement procedure, and are not accidentally disconnected.
Only use ground and supply cables provided by OMICRON.
The counterpart of the high-current sockets are locking connectors.
To lock these connectors safely, insert them carefully until you feel a
“click” position. Now they are locked. Confirm this by trying to pull them
out. This should not be possible now.
To remove the locking connectors, unlock them by pushing them in
completely first, and then pull them out.

Preface
Power supply
Operating the CPC 100 without PE and ground connection is life-threatening and not permitted.
► Only operate the CPC 100 with a mains power supply connected to protective earth (PE).
Power supply from grounded grids (TN/TT)
Before a measurement is started, the CPC 100 automatically verifies the PE connection in
grounded grids (TN/TT).
► If this check fails, check the power cord and power supply.
If the error message persists, there is no intact connection to protective earth (PE).
This is life-threatening. In this case measurements are not permitted and cannot be performed.
Power supply from isolated grids (IT)
An IT grid is a grid structure where none of the active conductors are galvanically connected to
ground. In an IT grid, only the PE is connected to ground.
In IT grids, the check fails – even if there is a PE connection. This can be the case when the
CPC 100 is powered by a generator. Since every operation mandates a PE connection for the
operation of the CPC 100, you need to manually verify this.
If the CPC 100 is supplied by a generator, the equipotential ground or PE of the generator has
to be grounded properly.
► If this is not possible, measurements are not permitted and cannot be performed.
Additional information
Instead of supplying the CPC 100 from phase-neutral (L1-N, A-N), it may also be supplied from
phase-phase (for example, L1-L2; A-B).
► Make sure that the voltage does not exceed 240V AC.
► Make sure that the power supply is fuse-protected (16 A automatic circuit breaker).
► Do not use an extension cable on a cable reel to prevent an overheating of the cord; run out
the extension cord.
► Keep extension cables as short as possible to prevent power loss.
If the power supply is ≤ 190V AC, the CPC 100 cannot provide the full output power at the
800A AC output. The same applies when an external current booster is used.
► Therefore, in order to gain the full output power, provide a sufficient power supply
(190 V ... 240 V AC).
The Ext. Booster connector is always galvanically connected to mains and active.
This also applies when no external booster is selected, the green status light (0) is on, the
outputs are turned off, or the Emergency Stop button is pressed.
► Handle the Ext. Booster connector with extreme caution.
► Only use booster cables supplied by OMICRON.
► Do not use booster cables that are frayed or damaged in any way.
Changing fuses
1. Ground the test object, and disconnect it from the CPC 100. By disconnecting it, you prevent
a possibly faulty test object feeding power back into the CPC 100.
2. Turn off the CPC 100 and unplug the power cord. Then press the Emergency Stop button.
Wait for about 30 seconds. This time is necessary for the internal electrolytic capacitors to
fully discharge.
3. Locate the blown fuse on the front panel of the CPC 100, and replace it.
Note: Replace with identical fuse type only (refer to the chapter “Changing Fuses” of the
CPC 100 Reference Manual available in PDF format on the Primary Test Manager DVD or the
CPC 100 Start Page).
DC output to test objects with a high inductance
► Only use the dedicated test cards for DC measurements on assets with inductive
characteristics:
► Never open the measuring circuit while current flows.
► After a measurement, wait until the test device has discharged completely.
► Ground all terminals of the test object before touching the test setup.

Preface - 5
► Short-circuit the terminals before disconnecting the test leads.
► Disconnect cables not used for testing both from the test object and the test device.
Discharging after tests on objects with a high inductance
After a winding resistance measurement, the CPC 100 monitors the reduction of the current and
voltage levels to zero. During this discharge process, the red status light flashes.
In the Demag test card, the discharging process is displayed as a status message
(see "Demagnetization" on page 10).
Note: When you disconnect a cable during the discharge process, even low voltage presents
considerable danger as it suddenly increases to a very high level when the circuit is
disconnected.
► Do not touch or disconnect any part of the test setup until the current and voltage levels have
reduced to zero.
► If the measurement is interrupted due to, for example, an unexpected loss of supply voltage
or erroneous behavior of the CPC 100 do not touch the test setup until the energy has
dissipated over time.
Note that the length of time depends heavily on the asset under test.
CPC 100 in combination with the CP TD
The CP TD (CP TD1, CP TD12 and CP TD15) is an optionally available high-precision test
system for on-site insulation tests of high-voltage systems like power and measuring
transformers, circuit breakers, capacitors and isolators. The CP TD works as an add-on device
to the CPC 100 and is described in chapter ”CP TD” of this User Manual.
On principle, the safety instructions that apply to the CPC 100 and its accessories also apply to
the CP TD. However, the CP TD requires some additional precautions and measures. They are
listed in chapter ”CP TD” on page CP TD1-1.
In all other affected tests, the
discharge progress is displayed in a
dialog.

Test cards
The CPC 100 software comprises a number of test cards. A test card carries out one specific
test, e.g., measuring a CT excitation curve, or testing the ratio of a voltage transformer.
A test card holds a number of user-definable test settings and - after the test was run - test
results.
Test procedure
A test procedure contains multiple test cards.
The composition of such a test procedure and the settings of all single test cards can be freely
defined by the user. Within a test procedure, each test card and its associated test is executed
individually in a user-defined order.
Report
For archiving or reporting purposes, or later processing, a test procedure with all of its test cards,
specific settings and - after the test was run - test results and assessments can be saved. It is
then considered a report.
Such a report can later be opened any time in the CPC 100’s File Operations menu.
Note: For detailed information about test cards, test procedures and templates, refer to section
“How to Use The CPC 100 Software” of chapter “Introduction” in the CPC 100 Reference

Introduction
The Test Procedure Overview lists all test cards of the currently active test procedure in a list
box showing the card’s name, its creation date and time, whether test results are available and
the test card’s assessment status.
Note: For detailed information refer to section “Test Procedure Overview” of chapter
“Introduction” in the CPC 100 Reference Manual available in PDF format on the
CPC 100 Toolsets or CPC 100 Start Page.
The highest hierarchical level of the CPC 100 file system, the “root”, is named CPC 100. Below
this, you can create additional folders in a tree-structure of your choice, save tests in these
folders, and perform file operations, such as open, save, rename, copy, paste etc.
The CPC 100 file system differentiates two file types:
Note: The file containing the up-to-date measurements should be saved regularly. If the test unit
is switched off, or in case of a power outage, all unsaved measurements will be lost.

The Accessories tab comprises safety-relevant settings for the CP TD. The settings you
choose in this view serve as a default for all corresponding test cards you set up afterwards.
Note: Per default and after start-up, the check boxes are activated.
2. Perform shield check
The shield check verifies if both the high-voltage connector and the grounding terminal are
connected to the CP TD. In certain cases, for example when strong interferences are present
during testing or when compensating reactors (e. g. the CP CR500) are used, the shield check
will prompt a false error message.
3. Perform loop check
The loop check verifies the connection to the device under test. When measuring very low
capacities, the resulting weak signal might cause the loop check to falsely state that no device
under test is connected.

Range
The output range combo box provides a list of available output ranges if the respective external
booster was selected at the Options tab Device Setup or on the Settings page.
The Settings page allows setting the test cards individually. At the Device Setup tab in the
Options view (see page Introduction-5), the same properties can be set for all test cards of a
test procedure. As a rule, do not use the Settings page but the Device Setup tab in the Options
view to set the test cards. Making different settings for the test cards is rarely a good idea. Set
the test cards individually using the Settings page only in well-founded cases.
If a test card contains results, the settings cannot be changed. When a file containing results is

Death or severe injury caused by high voltage or current
Together with the test object’s capacitance, the leakage inductance of the CPC 100’s
internal output transformer forms a series resonant circuit. Especially at
frequencies > 50 / 60 Hz this may result in voltage superelevation.
► When testing capacitive test objects using voltages ≥ 500 V, make sure that the
test object’s capacitance does not exceed 25 nF.
DANGER
Death or severe injury caused by high voltage or current
► Never use Quick in combination with a DC output on test objects with highly
capacitive characteristics.
► Mind the danger of test object’s charged capacitance. Before connecting or
disconnecting any leads, use a grounding/discharging rod
► to discharge all terminals of the test object.
► to connect all terminals of the test object to ground and short-circuit all
capacitances.
DANGER
Death or severe injury caused by high voltage or current
► Never use Quick to measure the resistance of windings with highly inductive
characteristics. Turning off the DC source results in life-threatening voltage levels.
► For this kind of measurement only use the special winding resistance test cards
RWinding, TRTapCheck or OLTC-Scan.

If the output quantities of the selected output can be measured, the combo boxes “1st measured
quantity” and “2nd measured quantity” provide IOut and / or VOut for selection.
I Out sel and V Out sel designate the frequency-selective measurement to filter out
interferences as they usually occur in substations. The measured input is filtered according to
the set output frequency.
Sync w/ V1 AC
Note: Sync w/ V1 AC is not available in all output modes.
A trigger is the occurrence of a selected event, for example, a binary trigger is the first change
of the state at the binary input.
Note that some of the trigger events offered in the Trigger on: combo box depend on the
measured quantity settings below (trigger on measurement).
Trigger on “Overload”: the occurrence or the clearing of an output overload condition (clearing
is delayed by 100 ms to debounce).
After having set all necessary parameters, press the I/O (test start/stop) push
button. The Quick test card enters the “on” state, the set power output value is
switched to the CPC 100’s outputs, the measuring continues.
Pressing the Quick test card menu key Keep Results saves the currently
measured values and “freezes” their display in the measurement table. Both the
“measuring” and the “on” state remain active, the measurement continues in a
new line of the measurement table.
Set Sync w/ V1 AC by pressing the menu key that appears when the focus is on
the frequency / phase angle data entry field.
This synchronizes the CPC 100 output frequency with the V1 AC input frequency
(we recommend a minimum input voltage of 10 V on V1 AC, possible range 48 -
62 Hz). In this case the phase angle of the output is displayed rather than the
frequency. Set the phase angle value relative to the phase angle of the V1 AC
input signal.
The icon next to the frequency / phase angle data entry field reflects the actual
setting.
Due to the PLL (phase locked loop) technology, the synchronization with V1 AC
takes places about 100 ms after the test was started.
