Preface

CPC 100 V 3.20
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 CPC 100 Toolset CD-ROM 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 safe and high-voltage area using different OMICRON electronics
GmbH devices
►Do not enter the high-voltage if the red warning light of the CPC 100 is on.
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
either the POWER ON/OFF switch or the Emergency Stop button. Never connect or
disconnect a test object while the outputs are active.
►Even if you switched off the CPC 100, wait until the red I/ O warning light is fully
extinguished. As long as this warning light is lit, there is still voltage and/ or current potential
on one or more of the outputs.
►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 800 A 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.
►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.
►Use only one CPC 100 output at a time.
FOR YOUR OWN SAFETY
Always follow the 5 safety rules:
1. Insulate
2. Secure to prevent reconnecting
3. Check insulation
4. Earth and short-circuit
5. Cover or shield neighboring live parts

CPC 100 V 3.20
Preface - 3
►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 electronics (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, 400 A DC and 800A AC, Ext. Booster), only use the specially manufactured
cables supplied by OMICRON electronics (refer to the chapter “Accessories” of the
CPC 100 Reference Manual available in PDF format on the CPC 100 Toolset CD-ROM
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 800 A 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 warning 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 warning
light indicates that the CPC 100 outputs are not activated.
Note: If none or both warning lights are on, the unit is defective. Do not use it anymore.
►Both of the high-current output sockets on the left-hand side of the test set (400 A 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 400 A 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, call the OMICRON electronics hotline (refer to cover page of
this User Manual.
Power Supply
►Supply the CPC 100 only from a power outlet that has protective earth (PE).
►An error message (313) appears if either the PE connection is defective or the power supply
has no galvanic connection to ground. In this case, make sure that the PE connection is
intact. If the PE connection is intact and the error message still appears, select the Disable
ground check check box at the Device Setup tab in the Options view.
►Ground the isolating transformer outputs or generators used to supply the CPC 100 on the
N (neutral) output or select the Disable ground check check box as described above.
►Instead of supplying the CPC 100 from phase - neutral (L1-N, A-N), it may also be supplied
from phase - phase (e.g., L1-L2; A-B). However, the voltage must not exceed 240V AC.
►Fuse-protect the power supply (16A slow-acting fuse).
►Do not use an extension cable on a cable reel to prevent an overheating of the cord; run out
the extension cord.
►The connector “Ext. Booster” is always galvanically connected to mains, regardless of
whether an external booster is selected on the software tab Options | Device Setup, the
green warning light (0) is on, the outputs are turned off or the Emergency Stop button is
pressed. Handle with extreme caution. Do not use any booster cables other than those
supplied by OMICRON electronics.
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
Changing Fuses
►Turn off the CPC 100, unplug the power cord and /or press the Emergency Stop button.
►We recommend to wait for about 30 seconds. This time is necessary for the internal
electrolytic capacitors to fully discharge.
►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.
►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 CPC 100 Toolset CD-ROM or the
CPC 100 Start Page).
DC Output to Test Objects with a High Inductance
Use test cards RWinding (winding resistance) and TRTapCheck (tap changer winding
resistance and on-load tap changer interruption check) only:
If a test object with a big inductance was connected to the CPC 100, short-out the test object
additionally before disconnecting it from the CPC 100.
CPC 100 in Combination with the CP TD1
The CP TD1 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 TD1 works as an add-on device to the CPC 100 and is described in chapter
”CP TD1” of this User Manual.
On principle, the safety instructions that apply to the CPC 100 and its accessories also apply to
the CP TD1. However, the CP TD1 requires some additional precautions and measures. They
are listed in chapter ”CP TD1” on page CP TD1-1.
Different Symbols for PE
The CPC 100 and CP TD1 use different symbols for protective earth (PE):
This is due to a new standard and does not symbolize any functional difference.
Note: Both symbols mean exactly the same, i.e., protective earth (PE) or equipotential ground.
DANGER
Death or severe injury caused by high voltage or current
►Never connect or disconnect test objects and/or cables as long as the on-screen
message “Switch off in progress” is displayed.
►Connect the CP SA1 discharge box to the VDCinput sockets when using the
400A DC output to protect yourself and the CPC 100 from high-voltage hazards.
►Use separate clamps for current and voltage connections on both sides of the test
object to avoid hazards in case one clamp falls off during the test.
The message Switch off in progress notifies you that, after the
CPC 100 was switched off, the connected external inductance
(i.e., the test object) still “feeds” voltage potential back into the
6A DC or 400A DC output.
The existence of this voltage potential at the 6A DC output is
also indicated by a lit LED - even if the CPC 100 is switched off.
If a test object with a big inductance is connected to the
CPC 100, ground the test object on both ends before
disconnecting it from the CPC 100.

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
Manual available in PDF format on the CPC 100 Toolsets or CPC 100 Start Page.

Quick - 1
Quick is the most basic mode to operate all of the CPC 100 outputs in a manual-like mode with
front panel control.
Range
The output range combo box provides a list of available output ranges including either CB2:,
CU20: or CU1: 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
loaded, the Settings page can be used to view the settings of the test procedure.
If the output quantities of the selected output can be measured, the combo boxes “1st measured
quantity” and “2nd measured quantity” provide IOutand / or VOutfor selection.
IOutseland VOutseldesignate 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.

Pressing the Settings menu key opens the Settings page. The Settings page
with the exception of the TRRatio test card looks as shown below.
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.
DANGER
Death or severe injury caused by high voltage or current
Together with the test object’s capacity, 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 capacity does not exceed 25 nF.
►Never use Quick to measure the resistance of windings with a high inductance.
Turning off the DC source results in life-threatening voltage levels.
►For this kind of measurement only use the special winding resistance test card
RWinding or the test card TRTapCheck.

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).
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.

Use the CTExcitation test card to record the excitation curve of a current transformer. This test
performs an automatic injection of a test voltage of up to 2 kV to the current transformer’s
secondary side.
The graph displays the test results in form of an interpolated curve with test point markers.
Turn the handwheel to set the focus onto the graph, and press it. This will bring up a crosshair
cursor that lets you navigate through the list of test points by using the keys Previous Point and
Next Point. Turning the handwheel has the same effect. The fields V: and I: display the value
pair of each test point.
Noise suppression: Select if you see unsteadiness and jumps in the CT excitation curve. The
unsteadiness or jumps can occur due to noise or disturbance during the measurement.
If noise suppression is selected, the measurement is done with a different frequency.
If fnom ≥60 Hz -> ftest =f
nom - 10 Hz.
If fnom < 60 Hz -> ftest =f
nom + 10 Hz.
The voltage will then be calculated back to fnom (V = Vmeas *f
nom/ftest). With fnom <60Hz,the
maximum test voltage is reduced up to 20 % and with fnom ≥60 Hz, the maximum test voltage
is increased up to 16 %. The exciting current will not be corrected as the influence is very small.

Use the test card RWinding to measure the resistance of a current transformer’s secondary
winding.
Note: If n/a appears in the VDCor Rmeasbox, the VDCinput is overloaded.
Use the test card VWithstand to measure the voltage withstand capability of the secondary
winding and secondary wiring. To do so, disconnect the burden. As shown in the following
figure, connect one cable of the 2kVoutput to the transformer’s secondary (1S1) winding
connection and the other cable to earth and the transformer’s primary connection (P1). Open
the secondary ground connection and ground the burden for safety reasons.
DANGER
Death or severe injury caused by high voltage or current
►Never open the measuring circuit while current flows.
►Check whether the red warning light “I” and the discharge LED are off before
disconnecting the device under test.
►Before disconnecting from the CPC 100, connect the device under test on both
ends to protective earth.

During the test, the test voltage increases in a ramp characteristic from 0 V to Vtest. Vtestis
then applied to the output for the specified time span. The measurements are continuously
taken. Afterwards, Vtestdecreases in a ramp characteristic.
Use the PolCheck test card to check a series of test points for correct polarity.
To do so, the CPC 100 injects a special polarity test signal at a certain location. This signal can
either be a voltage or a current signal from the CPC 100, and has a signal characteristic similar
to a saw-tooth signal with a different steepness for the rising and the falling slope.
The polarity check itself is then done with the CPOL accessory, a portable easy-to-use polarity
checker.
DANGER
Death or severe injury caused by high voltage or current
►Do not touch the terminal connected to the transformer’s secondary connection

If the CPOL detects the same signal characteristic at a test point, it considers the
polarity as OK, and lights up the green LED.
If the signal characteristic is inverted or distorted, the CPOL considers the polarity
not OK, and lights up the red LED.
If the CPOL detects a signal that is too low, both LEDs light up at the same time.
Remedy: increase the signal magnitude.
If the capacity of the CPOL’s battery gets low, the LEDs start flashing. As long as
the LEDs are flashing, the CPOL’s battery provides sufficient power to continue
working. However, the battery should be changed as soon as possible.
DANGER
Death or severe injury caused by high voltage or current
►Never operate the CPOL with an open battery compartment. A life-hazardous
voltage level may occur in the battery compartment if the CPOL’s probe touches a
test point with high-voltage potential!
►Handle with extreme caution: Do not touch the test point with your fingers.
►If you detect a wrong polarity in the current path, turn off the CPC 100 first, and only
then disconnect the terminals.
