Preface

Safety Instructions for the CPC 100 and its

Accessories

Caution: Before operating the CPC 100, read the following safety instructions

carefully. Do not turn on and do not use the CPC 100 without understanding

the information in this manual. If some points of the safety instructions are unclear, please contact OMICRON electronics.

Principle Use According to Regulations

•The CPC 100 should only be used in a safe manner, mindful of the dangers

while paying attention to the Reference Manual, and when it is in a technically sound condition and when its use is in accordance with the regulations. In particular, avoid disruptions that could in turn affect safety.

• If you have a cardiac pacemaker, do not use the CPC 100! Before operating the CPC 100, make sure there is no person with a cardiac pacemaker in the

immediate vicinity.

•The CPC 100 is exclusively intended for the application fields specified in

detail in ”Designated Use” on page 1-13.

Any other use is deemed not to be according to the regulations. The manufacturer/distributor is not liable for damage resulting from improper usage. The user alone assumes all responsibility and risk.

• Following the instructions provided in this Reference Manual is also considered part of being in accordance with the regulations.

• Do not open the CPC 100 housing.

Orderly Measures

• The Reference Manual, or alternatively the e-book in PDF format, should

always be available on the site where the CPC 100 is being used.

• Personnel assigned to use the CPC 100 should carefully read the Reference

Manual - in particular this section on safety instructions - before beginning to work with it. On principle, this also applies to personnel who only occasionally

work with the CPC 100.

• Do not undertake any modifications, extensions, or adaptations to the

CPC 100.

•Use the CPC 100 in conjunction with original accessories only.

1 - 5

Page 20

CPC 100 V 1.44

Operator Qualifications and Primary Responsibilities

• Testing with the CPC 100 should only be carried out by authorized and

qualified personnel. Clearly establish the responsibilities!

• Personnel receiving training, instruction, direction, or education on the

CPC 100 should remain under the constant supervision of an experienced

operator while working with the equipment.

Safe Operation

When setting the CPC 100 into operation, follow the instructions in ”Putting the

CPC 100 into Operation” on page 2-49.

If you have a cardiac pacemaker, do not use the CPC 100! Before operating the CPC 100, make sure there is no person with a cardiac pacemaker in the

immediate vicinity.

Note: Never use the CPC 100 without a solid connection to ground with at least

6 mm². Use a ground point as close as possible to the test object.

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 (see ”Device Setup” on page 2-

35).

• Ground the isolating transformer outputs 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 (for example, L1-L2; A-B). However, the voltage must not exceed 240V AC.

• Fuse-protect the power supply (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 power at the 800A AC output.

 190V AC, the CPC 100 cannot provide the full output

1 - 6

Page 21

Preface

The same applies when an external current booster is used. Therefore, in order to gain the full output power, provide a sufficient power supply (190V ... 240V AC).

Caution: The connector "Ext. Booster" is always galvanically connected to mains, regardless whether or not 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 other booster cables than the ones supplied by OMICRON electronics.

General

Warning: 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.

Note: 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.

Caution: At their output sockets and especially in the cables connected to them, in operation the high-current 400A DC and 800A AC outputs generate a significant amount of heat (approx. 300 W/m at 800 A). To prevent burns, use gloves when touching the cables while in operation or a short while after.

Warning: Do not insert objects (for example, 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 the special winding resistance test card RWinding!

• When measuring the ratio of voltage and power transformers make sure that the test voltage is connected to the corresponding primary winding, and the voltage of the secondary winding is the one that is measured. Accidentally

1 - 7

Page 22

CPC 100 V 1.44

mixing up the windings can generate life-threatening voltages within the transformer. For example: feeding a voltage of 100V / voltage transformer that has a ratio of 400000V / voltage of 400000V /

• 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!

DC output to test objects with a high inductance

Use the RWinding (winding resistance) and TRTapCheck (tap changer winding resistance and on-load tap changer interruption check) test cards only.

Warning: As long as the CPC 100 software shows the on-screen message

"Switch off in progress", NEVER connect or disconnect test objects and / or cables.

The message "Switch off in progress" notifies you

that, after the CPC 100 was switched off, the

connected external inductance (that is, the test object) still "feeds" voltage potential back into the 6A DC or 400A DC output.

1 - 8

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.

Warning: The CP SA1 (see ”CP SA1” on page 15-17) must be connected to the CPC 100 VDC input sockets when using the 400A DC output to protect yourself and the CPC 100 from high-voltage hazards.

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.

Page 23

Preface

High-voltage and high-current outputs

• Use 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 high-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 (for example, for the V2 AC measuring input).

– For the high-voltage and high-current output connectors on the left-hand

side of the test set (2kV AC, 400A DC and 800 A AC, ext. Booster), only use the specially manufactured cables supplied by OMICRON electronics (refer to ”Cables” on page 15-18). 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.

Warning: When the CPC 100 is switched on consider this part of the cable a

hazard of electric shock!

Warning: If you do not use the high-current 400A DC or 800A AC outputs or the high-voltage 2kV AC output, disconnect any cable that may be plugged in to these sockets. 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. This is a physical and an electrical hazard.

– 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 and must not be used anymore.

CPC 100 V 1.44

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 again, unlock them by pushing them in first, and then pull them out.

FOR YOUR OWN SAFETY

Always follow the 5 safety rules:

1. Insulate

2. Secure to prevent reconnecting

3. Check isolation

4. Earth and short-circuit

5. Cover or shield neighboring live parts

– 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.

Warning: However, in case of an internal insulation fault these outputs may carry up to 300 V. Consider these outputs life-hazardous!

– Always insert connectors completely.

– 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 at ”Technical Data” on page 14-1.

• Do not operate the CPC 100 in the presence of explosives, gas or vapors.

• Opening the CPC 100 invalidates all warranty claims.

•If the CPC 100 or any add-on device or accessory does not seem to function

properly, do not use it anymore. Please call the OMICRON electronics hotline.

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:

– 6.3A T (6.3 Amps slow-acting wire fuse 5x 20 mm) for AC OUTPUT in 6A

operation mode

– 3.15A T (3.15 Amps slow-acting wire fuse 5x20 mm) for AC OUTPUT in

130V operation mode.

– 10A FF (10 Amps very-quick-acting wire fuse 5x 20 mm) for measuring

inputs.

or for DC OUTPUT.

Note: Replace with identical fuse type only.

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 the CP TD1 Reference Manual contained on the CPC 100 Toolset DVD and the CPC 100 Start Page.

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 the CP TD1 Reference Manual.

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, that is, protective earth (PE) or equipotential ground.

1. The front panel output 6A/130V operates as either a 0 … 6A AC or a 0 … 130 V AC output. The output range and the actual values are set by the software.

In current mode 0 … 6 A, the maximum output voltage is 55 V (330 VA).

In voltage mode 0 … 130 V, the maximum output current is 3 A (390 VA).

The 6.3A T (6.3 Amps slow-acting wire fuse 5 x20 mm) protects both the AC OUTPUT in 6A current mode and the DC OUTPUT.

The 3.15A T (3.15 Amps slow-acting wire fuse 5x 20 mm) protects the AC OUTPUT in 130V voltage mode and in the 3A AC current mode.

2. The 800A output sockets are situated at the left-hand side of the CPC 100

as shown on page 2-3.

They provide an AC current of 0 … 800 A at a voltage of 6.1 … 6.5 V. The actual output power (4880 VA max.) is range-dependent. For details refer to ”High-Current and High-Voltage Outputs” on page 14-5.

The current that flows from this output is measured internally by the

CPC 100, and displayed on the respective test card.

3. The 2kV output sockets are situated at the left-hand side of the CPC 100 as

shown on page 2-3.

2 - 6

Page 37

Introduction

They provide an output voltage of either

• 0 … 0.5 kV with a maximum current of 5 A, or

• 0 … 1 kV with a maximum current of 2.5 A, or

• 0 … 2 kV with a maximum current of 1.25 A.

For details refer to ”High-Current and High-Voltage Outputs” on page 14-5.

Both the voltage of this output and the current that flows from this output are

measured internally by the CPC 100, and displayed on the respective test

card.

All outputs are overload and short-circuit-proof and protected against external high-voltage signals as well as over-temperature.

Note: The length of time a high current or a voltage can be applied may be limited due to a high temperature occurrence of the internal transformer windings and/or heat dissipaters. This high temperature occurrence may even

be increased if the CPC 100 is operated in a hot environment or is exposed to

direct sunlight. It is highly recommended not to exceed the typical duration time t

specified

max

for each current and voltage output (refer to ”CPC 100 Outputs” on page 14-5).

If you do, and the CPC 100 develops too high an internal temperature, the

outputs are shut off automatically.

DC OUTPUT

Programmable DC current output.

1. The 6A output provides a DC current of 0 … 6 A with a maximum output voltage of 60V (360W). The output value is set by the software.

The 6.3A T (6.3 Amps slow-acting wire fuse 5 x20 mm, situated at the front panel’s AC OUTPUT group) protects both the AC OUTPUT in 6A current mode and the DC OUTPUT.

2. The 400A output is situated at the left-hand side of the CPC 100 as shown

at ”High-Voltage and High-Current Outputs” on page 2-3.

They provide an output current of 0 … 400 A at a voltage of 4 … 4.5 V. The actual output power (2600 W max.) depends on the current magnitude. For details refer to ”High-Current and High-Voltage Outputs” on page 14-5.

View Selector

Lets you select the view of your choice, for example, Test Card View, Test Procedure Overview, File Operations or Options (refer to ”View Selector” on page 21 of this chapter).

Jog-dial handwheel

Advanced jog-dial handwheel with "click" (Enter) function.

In "navigation" mode, turning the handwheel navigates you through the UI (

 Glossary) elements within one test card. Pressing the Up/Down keys has

the same effect.

In "data entry" mode, that is, if the focus ( field or a combo box, and the handwheel was pressed to "enter" the field and to enable data entry, turning the handwheel increases/decreases the entry field’s value or browses through the preset values of the combo box, respectively.

Pressing the handwheel corresponds to the Enter function of the soft-touch keyboard.

Furthermore, the wheel comprises an adaptive acceleration function, that is, if the focus is, for example, set onto a data entry field, fast turning increments/

decrements a value in increasingly bigger steps, slow turning in decreasingly

smaller steps.

Up/Down keys

Soft-touch keys supplementing the handwheel. Depending on the current focus in the software user interface, pressing these keys either navigates through the UI elements within one test card, or - if in a data entry field, for example increments/decrements a value.

Contrary to the handwheel, the Up/Down keys change a value in fixed coarse increments /decrements in order to ease a quick approximation to the end value. The fine adjustment is then done with the handwheel.

Context-dependent menu keys

Soft-touch keys that directly invoke specific commands associated with the currently selected control of the test card and view.

Since their actual functions depend on the selected view, test mode, test card and selected UI element, the menu keys do not hold any specific text. The individual key function is displayed on the monitor with a labelled button symbol right next to the menu key.

I/O (test start/stop)

If the test parameters are set in the software’s Test Card View, the Emergency Stop button is released and the safety key lock is set to the "enable" position,

pressing this push-button enables the CPC 100 outputs and starts a test.

Pressing this push-button a second time stops the test.

Caution: Stopping a test does not shut off theCPC 100 outputs

instantaneously. First, the currently running test sequence finishes, then the test execution is stopped. Most test cards finish the running test sequence with a predefined ramp function. Therefore, in a hazardous situation never press "Stop Test". Instead, use Emergency Stop.

Introduction

How to Use the CPC 100 Software

Note: This manual refers to the CPC 100 software version V 1.44. Information about the software version of your CPC 100 can be found at the Options tab

System Info (refer to ”System Info” on page 43 of this chapter).

This section provides an overview of the front panel control components, explains in detail how to navigate with them through the software, how to set up a test, execute it, save it for later use, etc.

Note: The subsequent chapters (Quick, CT, VT, Resistance, Transformer...), explaining the various test procedures from a more practice-orientated point of view, are confined to test-relevant issues, and assume that you have read and understood this section.

The Principles of Test Cards and Test Procedures

• Test cards

The CPC 100 software comprises a number of test cards. A test card carries

out one specific test, for example, 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 card default

Rather than repeatedly filling out blank test cards with frequently used settings, any test card with its actual settings can be made a test card default for that particular type of card, for example, filling out a CTRatioV test card with certain values and pressing Save As Default makes this card the new CTRatioV test card default.

Each card of this type that will later be inserted to a test procedure will already hold these new settings.

Note: A test card default contains user-defined settings, not test results.

2 - 17

Page 48

CPC 100 V 1.44

• 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.

Note: With the CPC 100 V0, the number of test cards in one test procedure should be limited to 15 to avoid memory problems. The CPC 100 V1 allows

using more test cards in one test procedure but we recommend not to use more than 15 test cards to keep the tests clearly structured.

• Test procedure default

A test procedure with all of its test cards and specific settings - but without test results - can be made the test procedure default.

Note: When the CPC 100 software starts, it automatically loads the test

procedure default.

Initially, that is, as long as no user-defined test procedure default is created,

the the CPC 100 software loads one empty Quick test card.

• 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 CPC 100 File Operations

menu.

• Test procedure template

A report can be copied/ pasted to be a test procedure template.

In this process, the settings are preserved, however, the test results are deleted.

Starting the Software

When the CPC 100 is switched on, the operating system boots up, and the CPC 100 software starts automatically.

During the hardware and software initialization phase, the software displays a splash screen.

The CPC 100 software starts in the Test Card View loading the test procedure

default (refer to ”The Principles of Test Cards and Test Procedures” on page 17 of this chapter).

Initially, the test procedure default contains one empty Quick test card However, this default can be customized according to your specific requirements with as many test cards as needed and of all types of your choice.

By creating a user-defined test procedure default, the CPC 100 starts up loading

your most frequently used test cards already containing specific values.

To learn more about defining such a default, refer to ”Creating Defaults and Templates” on page 44 of this chapter.

The Test Card View comprises a number of context-dependent menu keys. Some examples are given below:

Note: The actual function of the context-dependent menu keys depends on the selected view, test mode, test card and selected UI element. To make the above listed functions visible, the focus ( onto the test card tab designation, for example, CTRatioV.

 Glossary) must be set

Inserting Test Cards

The Insert a new test card dialog box displays the available tests and their associated test cards in a tree-like structure.

Figure 16: Insert a test card

Use the context-dependent Up/ Down menu keys to the right, or the handwheel, to browse through the structure.

2 - 23

Page 54

CPC 100 V 1.44

Due to usability reasons, some test cards, such as Winding Resistance, Voltage Withstand Test or Polarity Check, appear in more than one test mode, e.g., Winding Resistance appears in Current Transformer, Power Transformer and Resistance.

With regard to their functionality, these test cards are identical.

To expand a collapsed group of tests , for example, CT, set the focus onto this group, and press Enter or the handwheel.

The group of tests expands and displays all of its associated test cards.

Browse to the test card of your choice, and when its highlighted press Enter.

This will switch from the Insert a new test card dialog to the Test Card View, inserting the test card of your choice after the last selected test card in the Test Card View.

Note: Only test cards that are licensed can be inserted.

When you purchased the CPC 100, you purchased a license for a number of test

cards of your choice. Not licensed test cards are displayed in the Insert a new test card dialog, but the attempt to insert one of them to the test procedure results in an according on-screen message. If you wish further information about licensing, please contact OMICRON electronics.

2 - 24

You can insert as many test cards as needed and of all types of your choice by repeating this process.

Note: With the CPC 100 V0, the number of test cards in one test procedure should be limited to 15 to avoid memory problems. The CPC 100 V1 allows

using more test cards in one test procedure but we recommend not to use more than 15 test cards to keep the tests clearly structured. If you need more test cards in one test procedure, we recommend not to save all cards in one, for example, the test procedure default, but to combine a smaller number of cards to logical groups, and to save these logical groups as test procedure templates with individual names (refer to ”Test Procedure Templates” on page 47 of this chapter).

Pressing Esc closes Insert a new test card, and brings you back to the previous view without inserting a new test card.

Page 55

Introduction

Within one test card, to navigate to the UI element of your choice either turn the handwheel or use the Up/Down keys at the right-hand side of the handwheel.

A selected UI element is entirely highlighted; it has the focus (

 Glossary).

If a data entry field, for example, "Imax:" has the focus, press the handwheel to "enter" and enable the field.

Setting Up a Test Card

Note: Each parameter whose numerical value can be changed in a data entry

field has an associated minimum and maximum value as well as a preset number of decimal characters. The parameter value can be changed freely within this min. … max. range.

Furthermore, each numerical value has a

• fixed precision value that is used as a step size when increased/decreased by means of the handwheel

• a coarse step value that is used as a step size when increased/decreased by pressing the Up/Down keys.

As shown above, the value itself is highlighted, the unit is not, and at the value’s end a blinking caret (cursor) indicates "ready for data entry".

Now either

• use the Up/Down keys to approximate the value of your choice quickly in coarse predefined steps

• rotate the handwheel to fine-adjust the value in precision steps

• type in the value of your choice using the numeric soft-touch keys to the left of the handwheel (refer to Figure 17).

Soft-touch keys to enter numerical values.

Decimal point

: backspace

Esc: cancels the current action without saving

— : prefix for negative values, for example, angles

: Enter

Figure 17: Soft-touch keys to enter numerical values

Pressing Esc on the soft-touch keyboard while entering a value, discards the entry and restores the previous value.

When ready, press either the handwheel again or the Enter key to confirm your entry, and move forward to the next UI element of your choice by turning the handwheel or the Up/ Down keys.

Note: If a number key is pressed with the focus set onto a data entry field, this number is automatically written to the data entry field, and the field is enabled for data entry.

Pressing the context-dependent menu key Back to Top terminates the data entry mode, accepts all current values and sets the focus onto the test card tab designation.

Combo Box

The same principle applies at a combo box, for example, :

• press the handwheel (to "enter" the combo box for selection)

• and either navigate through the list of available parameters by rotating the handwheel, or by using the Up/Down keys.

Pressing Esc while scrolling through the list of values closes the combo box and returns to the previous value.

Check Box

Set the focus onto the check box, for example,

and press

either the Enter key or the handwheel to select /clear a check box.

2 - 26

Page 57

Figure 18: Example of a list box

Introduction

List Box

List boxes are differentiated between read-only and editable list boxes:

• In a read-only list box (Figure 18), turning the handwheel scrolls from line to line.

When using the Up/ Down keys, a read-only list box is treated as one UI element, that is, pressing one of the keys exits the list box, and sets the focus onto the next /previous UI element.

• In an editable list box, turning the handwheel scrolls from table cell to table cell. Press either the handwheel or Enter to "enter" a cell and to edit the value.

When using the Up/ Down keys, the focus proceeds to the same table cell one line above or below.

Figure 20:

Settings page

Settings Page

Some test cards include the Settings menu key. Pressing the Settings menu key opens the Settings page.

The Settings page with the exception of the TRRatio test card looks as shown below.

2 - 28

The Settings page allows setting the test cards individually. At the Device Setup tab in the Options view (see ”Options” on page 35 of this chapter), the same properties can be set for all test cards of a test procedure. As a rule, do not use the Settings page described here 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.

Page 59

Introduction

Starting a Test

Note: Tests can only be started and stopped with the I / O (test start / stop) push-

button while in the Test Card View. Each test card represents a separate test, and is started individually.

Preconditions to start a test

1. The required test card is defined, the test parameters are set.

2. The software is in the Test Card View.

3. The Emergency Stop button is released.

4. The safety key lock is set to the "enable" position.

Pressing the I/O (test start/ stop) push-button starts the test. Pressing this push-button a second time stops the test.

Note: Stopping a test does not shut off the CPC 100 outputs instantaneously.

First, the currently running test sequence finishes, then the test execution is stopped. Most test cards finish the running test sequence with a predefined ramp function.

Caution: Therefore, in an emergency situation never press "Stop Test". Instead, use Emergency Stop.

While a test is running, several functions such as changing the test card, changing the view etc., are disabled.

To repeat the test, the test results need to be cleared beforehand. Otherwise the start is blocked.

2 - 29

Page 60

CPC 100 V 1.44

Temperature Monitoring

Each test card contains a progress bar-like temperature gauge that displays the

CPC 100 actual temperature condition. When the temperature limit is reached,

that is before an overheating condition occurs, the output is switched off automatically.

In addition, if an output is activated, both the CPC 100 current consumption from

the power supply and the current emitted at the high-current outputs is monitored and, together with the temperature, displayed by this temperature gauge. The temperature gauge’s bar therewith represents an indicator for the

remaining time the CPC 100 can output power.

Just as with over-temperature, if these limit values are exceeded, the output is switched off automatically.

With deactivated outputs, the temperature gauge’s bar represents an indicator how much the device has already cooled off.

Note: To reach a maximum output time, we suggest to let the CPC 100 cool off

completely before switching it on again.

Note: For each line of measurement results there is a separate overload

indication top right on the CPC 100’s screen (or in the report) explained below.

No overload indication means no overload during that step of the measurement sequence. In the test report, "No" appears in the overload field or column.

Dotted overload indication means that there was an overload during that step of the measurement sequence but not all the time. In the test report, "Yes" appears in the overload field or column.

Solid overload indication means a permanent overload during that step of the measurement sequence. In the test report, "Yes!" appears in the overload field or column.

Figure 21: Test Procedure Overview

Introduction

Test Procedure Overview

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.

Pressing Insert Card switches to the Insert a new test card dialog. After inserting a new test card, the software automatically switches to the Test Card View, inserting the test card of your choice after the last selected test card in the Test Card View.

Pressing Esc at Insert a new test card brings you back to the previous view without inserting a new test card.

Delete Card deletes the currently highlighted test card from the test procedure.

With Save As Default, Test Procedure Overview provides a function to save the current test procedure as the test procedure default, that is the default the

CPC 100 software will start with in future.

To learn more about defaults, refer to section ”Creating Defaults and Templates” on page 44 of this chapter.

Unlike in Test Card View, where all context-dependent menu keys apply for that particular card only, the Test Procedure Overview has an additional menu item that applies for all test cards: whereas Clear Results clears the test results of the currently highlighted test card only ("Comment" in Figure 21), Clear All Results applies to all test cards, that is, clears the results of all cards listed in the Test Procedure Overview.

After both Clear Results and Clear All Results, re-start the test in the Test Card View by pressing the I/O (test start/stop) push-button.

Automatically switches back to the Test Card View, and opens the test procedure default. If the current test procedure contains unsaved data, you will be asked whether or not you want to save them before you proceed.

The CPC 100 File System

The CPC 100 File Operations resemble the functionality known from, for

example, the Windows Explorer. File Operations comprises a File and an Edit submenu with additional menu items as well as an Open and various Save... functions.

2 - 32

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 carry out file operations, such as open,

save, rename, copy, paste etc. For CPC 100 V1 units with a USB memory stick

plugged in, a second tree root USB Disk is displayed as shown above.

The CPC 100 file system differentiates two file types:

name.xml A test procedure with all of its test cards and specific settings.

An .xml file may also contain test results and assessments that

were stored together with the settings as report in the CPC 100

file system for archiving purposes.

name.xmt Test procedure template, that is, a user-defined template

containing one or more test cards with all of their specific test settings but without test results.

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.

Table 1: Instantiation procedures

Introduction

Options

Note: Changes made in the Options view are automatically saved when the

view is changed (for example when Options is left to change to Test Card View). Alternatively, changes can be saved instantly by pressing Save Options.

Upon a power supply loss or an accidental switching off of the CPC 100,

unsaved changes are lost, and the old values are restored.

Device Setup

The Device Setup tab in the Options view allows you to change the settings of

all test cards of the test procedure running on the CPC 100 and all test cards

inserted afterwards. The test cards can be instantiated in different ways and for different purposes. Table 1: ”Instantiation procedures” below displays the instantiation procedures and the associated default values.

Procedure Default values

New test card Booster, clamp and default frequency

set in the Options view

New test card saved as default Booster and clamp set in the Options

view

New test procedure from template (*.xmt)

New procedure from report (*.xml) Booster, clamp and frequency remain

Booster, clamp and frequency remain as defined in the template

as defined in the report

Because the settings of a test card containing results cannot be changed, the settings made at the Device Setup tab in the Options view apply only to new test cards if the currently loaded procedure contains results. To change the settings of a test procedure containing results (for example, after pressing the

Keep Results menu key or after loading a file), clear the results by pressing the Clear Results menu key in all test cards before setting the test procedure in the Options view.

It is strongly recommended to set the test cards using the Options view. In wellfounded cases, you can alternatively set a test card individually using the Settings menu key (see ”Settings Page” on page 28 of this chapter).

External booster

The "External booster" combo box allows to set the external booster:

• CB2 for the CP CB2 current booster

• CU20 for the CP CU20 coupling unit

• CU1 for the CP CU1 coupling unit

For the default value associated with different instantiation procedures, see Table 1: ”Instantiation procedures” on page 35.

Clamp & input transformer settings

When an input is not connected to the device under test directly but using a current clamp, a CT or a VT, the ratio of these devices can be set here.

The Clamp & input transformer settings group box displays and, if required, allows you to change settings for external devices:

• IClamp for the current clamp parameters

• CT for the transformation ratio of the current transformer

• VT for the transformation ratio of the voltage transformer

By default, the transformation ratios of the current and voltage transformers for the selected external device are preset. For the default value associated with different instantiation procedures, see Table 1: ”Instantiation procedures” on page 35.

Introduction

Disable ground check

Warning: Operating the CPC 100 with the "Disable ground check" check box

selected can cause injury or possibly death of the operating staff if the power supply is not metallically separated and the PE (protective connection) is defective.

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.

Note: After the CPC 100 has been rebooted, the "Disable ground check" check

box is cleared for safety reasons.

Default freq.

The "Default freq." data entry field allows you to enter the default frequency. For the default value associated with different instantiation procedures, see ”Instantiation procedures” on page 35 of this chapter.

Auto Save

As the name implies, the Auto Save feature automatically saves the current test settings in fixed intervals. These intervals can be set in the "Auto Save" box. There are three time intervals available (10, 30 or 60 minutes), and the option

OFF which disables Auto Save. Auto Save saves all actual data to a file named lastmeas.xml. So depending

on the set time interval, in case of a system crash, lastmeas.xml may contain more actual data than the last manually saved test. The file is created during the next booting process.

When Auto Save saves test settings, it pops up a dialog notifying you about it.

Auto Save works in Test Procedure Overview, File Operations or Options without any restrictions. In Test Card View, Auto Save does not work as long as a test is running, or as long as inputs are measured (for example, in Quick).

In a case like this, Auto Save repeats the attempt to save the test settings in intervals until it succeeds, that is, until the test is finished and it can save the data. After this, Auto Save returns to the set time interval.

example, a notebook and via a PC network. At the Network tab the communication settings are specified.

In the combo box select between

DHCP/Auto IP Configures all communication parameters automatically;

the DHCP server will do it for you or it will be done via the Auto IP mechanism. The data entry fields for IP address, Subnet Mask, Default Gateway and DNS are read-only, no data can be entered. This is the recommended setting.

Static IP Configure the communication parameters manually by

entering the values into the data entry fields using the softtouch keys.

Section ”CPC 100 in a Network” in chapter 10 explains in detail how to connect

the CPC 100 to either a stand-alone PC or a PC network, and how to configure

such a connection.

Once the communication parameters are configured, press Save Options to save them to the Windows Registry.

For a change to come into effect, the operating system needs to be re-booted,

that is, the CPC 100 restarted.

Options tab Service

Service

During operation, the CPC 100 creates a logfile with a user-definable logging

level (see below).

Every time the CPC 100 is switched on, it generates a new logfile, and saves the

existing one as the "previous" logfile. This way, the occurrences of the previous and the current session can be viewed.

2 - 41

Page 72

CPC 100 V 1.44

The logging level specifies the occurrences to be recorded in the logfile:

Logging level: Records

None nothing

Error internal errors, hardware errors, operational errors,

overload conditions etc.

Warning uncritical errors such as over-temperature, malfunction

etc.

Info additional operational information about the CPC 100.

This setting is suggested if the operator suspects, for example, an incorrect functioning or an operational

malfunction of the CPC 100. This setting records every relevant operational activity of the CPC 100.

The logfile can then be sent to OMICRON electronics for diagnosis.

The default setting is Warning.

Note: The logging levels are hierarchical, that is, if logging level Warning is set, Errors are also recorded, or if Info is set, the logging levels Warning and Error

also apply.

If the logfile gets quite long, use either the scroll bar or the buttons Page Up/

Page Down to navigate up and down in the list of logged occurrences.

Clear Log deletes all logfile entries and starts recording occurrences anew.

Creating Defaults and Templates

The CPC 100 software differentiates three types of templates:

1. test card default

2. test procedure default (default upon start-up)

3. test procedure templates.

Note: Pressing the Restore Defaults menu key at the Options tab Device

Setup resets all user-specific settings made in the CPC 100 software to factory-

defined defaults. This includes the test card defaults and the test procedure default.

Test Card Default

Rather than repeatedly filling out blank test cards with frequently used settings, any test card with its actual settings can be made a test card default for that particular type of card, for example, filling out a Quick test card with values and pressing Save As Default makes this card the new Quick test card default.

Note: The actual function of the context-dependent menu keys depends on the selected view, test mode, test card and selected UI element.

To make the function Save As Default visible, the focus (

 Glossary) must be set onto the test card tab designation, for

example, Quick.

Each card of this type, here Quick, that will later be inserted to a test procedure will already hold these new settings.

Note: A test card default contains user-defined settings, not test results.

In the CPC 100 file system, a test card default is not visible as a "file" (refer to

”The CPC 100 File System” on page 2-32).

2 - 44

Page 75

Introduction

Test Procedure Default

The CPC 100 software always starts with the test procedure default. Initially,

that is, as long as no user-defined test procedure default is created, this default contains one empty Quick test card. However, this default can be customized according to your specific requirements with as many test cards as needed and of all types of your choice.

Note: With the CPC 100 V0, the number of test cards in one test procedure should be limited to 15 to avoid memory problems. The CPC 100 V1 allows

Introduction

Test Procedure Templates

A test procedure template is a user-defined test procedure, and can be created

from any test procedure that was saved to the CPC 100 file system beforehand (a name.xml file; refer to ”The CPC 100 File System” on page 2-32).

To create a test procedure template from an .xml file

• go to "File Operations"

• highlight the name.xml file of your choice

•select Edit | Copy to copy the test procedure

•select Paste As Templ.

• a file name.xmt is generated. If this file name.xmt already exists, you will be asked whether or not to

overwrite the existing file.

If you answer this question with No, the String Editor opens (refer to ”The

String Editor” in chapter 9).

Give the test procedure template a name of your choice (max. 15 characters), and select OK. The file name extension .xmt is appended automatically.

In this process, the settings of the original name.xml file are taken over to the newly created test procedure template name.xmt. The test results, however, are not taken over.

The original file name.xml remains unchanged.

Introduction

Putting the CPC 100 into Operation

Note: Before setting the CPC 100 into operation and carrying out a test, it is

essential that you have read and understood the section ”Safety Instructions for the CPC 100 and its Accessories” on page 1-5.

Always be aware that all AC and DC output sockets of the CPC 100 can carry

life-hazardous voltage potential and provide life-hazardous currents.

Safety Aspects

We strongly advise you to obey the following legal safety aspects:

• Tests with such high voltages and currents must only be carried out by authorized and qualified personnel.

• Personnel receiving training, instructions, directions, or education on highvoltage/current tests should remain under the constant supervision of an experienced operator while working with the equipment. The instructions have to be renewed at least once per year.

• The instructions must be available in written form and signed by each person assigned to do high-voltage/ current tests.

Preparations in Substation

Warning: Prior to connecting a test object to the CPC 100, the following steps

need to be carried out by an authorized employee of the utility.

• Turn off and disconnect the high voltage from the test object.

• Protect yourself and your working environment against an accidental reconnection of high voltage by other persons and circumstances.

• Verify a safe isolation of the test object.

• Earth-connect and shorten out the test object’s terminals using a grounding set.

• Protect yourself and your working environment with a suitable protection against other (possibly live) circuits.

• Protect others from accessing the dangerous area and accidentally touching live parts by setting up a suitable barrier and, if applicable, warning lights.

• If there is a longer distance between the location of the CPC 100 and the

area of danger (that is, the test object), a second person with an additional "Emergency Stop" button is required.

3. Connect the CPC 100 to the mains power supply using the provided cable.

4. With the test object grounded and shorted out, connect the CPC 100 to the

test object according to your requirements.

5. Remove the grounding set from the test object.

6. Turn on the CPC 100 at its POWER switch at the left-hand side. The green warning light "O" lights up, showing that none of the CPC 100

outputs carries a dangerous voltage or current yet.

7. Set up your test in the CPC 100 software, and, where applicable, determine

whether you want to perform an automatic or a manual test.

The following chapters of this manual comprise an example for each available test.

For a detailed description of how to use the software refer to section ”How to Use the CPC 100 Software” on page 17 of this chapter.

8. Once all test cards are prepared and the parameters set, make sure the safety key lock is in position "release" (horizontal).

Page 81

Introduction

9. Start the test by pressing the green I/ O (test start /stop) push-button on the

CPC 100 front panel.

Notes: • A test can only be started in the Test Card View and with all

preconditions met (refer to ”Starting a Test” on page 29 of this chapter).

• If voltages (test start/stop) push-button for the first time a warning message appears on the screen.

Only after the I/O push-button is pressed a second time, the

voltage is applied to the CPC 100 output.

 1 kV are to be applied, after pressing the I/O

Rather than starting a test and activating the outputs, pressing the I/O (test start/stop) push-button will then pop up a message box notifying you about this problem.

10.If a potentially hazardous voltage and/or current level is applied to the

CPC 100 outputs, the red signal red light "I" starts flashing.

11.After testing, switch off the high voltage or current immediately with the I/O (test start/stop) push-button.

12.If you do not use the CPC 100 anymore, turn the safety key to "lock" (vertical)

and remove the key to avoid anybody accidentally turning on the high voltage or current.

Note: After

only when the CPC 100 green warning light is on and the red one off, switch

off the safety key lock and take off its key.

13.After turning off the CPC 100 outputs, earth-connect and short-circuit the

test object’s terminals again using a grounding set.

14.Remove the connection between the CPC 100 and the test object.

Warning: Never touch any metallic terminals and / housing components without a visible ground connection!

About Quick

Quick is the most basic mode to operate all of the CPC 100 outputs in a manual-

like mode with front panel control.

The CPC 100 starts in the Test Card View (refer to ”Test Card View” on page 2-

22) with the test procedure default. Initially, the test procedure default contains

one empty Quick test card. However, this template can be customized according to your specific requirements with as many test cards as needed and of all types of your choice.

By creating a user-defined test procedure default, the CPC 100 starts up loading

your most frequently used test cards already containing specific values.

To learn more about defining such a template, refer to ”Creating Defaults and Templates” on page 2-44.

3 - 1

Page 84

CPC 100 V 1.44

Quick starts in "measuring" state with de-activated outputs, displaying the

measured values in the measurement table of the Quick test card.

The measurements as well as the indication of the binary input’s signal status (refer to ”Bin.In:” on page 11 of this chapter) are updated with an interval of approx. 0.5 s.

After having set all necessary parameters (more about this in the following sections), 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

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.

While in "on" state, pressing the I/ O (test start / stop) push-button terminates the

test. The CPC 100 outputs are turned off, and Quick returns to the "measuring"

mode.

Caution: When testing capacitive test objects using voltages  500 V, make sure that the test object’s capacity does not exceed 25 nF. Together with the test object’s capacity, the leakage inductance of the CPC 100 internal output transformer forms a series resonant circuit. Especially at frequencies > 50 / 60 Hz this may result in voltage superelevation.

Caution: Never use Quick 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 the special winding resistance test card RWinding!

Pressing the Settings menu key opens the Settings page. The Settings page allows setting the test cards individually. As a rule, do not use the Settings page but the Device Setup tab in the Options view (see ”Device Setup” on page 2-

35) to set the test cards. For more information, see ”Settings Page” on page 2-

28.

Figure 2: Characteristics of the frequency-selective measurement

The Frequency-Selective Measurement

The frequency-selective measurement is used to filter out interferences as they

usually occur in substations. To do so, the frequency of the CPC 100 output

quantity is set to a value different from the substation’s frequency, for example,

the substation operates with a frequency of 50 Hz, the CPC 100 output

frequency is set to 55 Hz.

The quantity measured back at the CPC 100 input is measured selectively, that

is, only a quantity with the specified frequency is fully taken into consideration for the measurement. Quantities with different frequencies are filtered out according to the characteristics shown in Figure 2.

Apart from Quick, the frequency-selective measurement is also available for other test cards:

•CTRatio

• CTBurden

•CTRatioV

• CTLowPower

In Quick, Sequencer and Ramping the frequency-selective measurement is selectable, whereas at the other test cards, it is preset and cannot be cleared.

•VTRatio

• VTBurden

• VTElectronics

Range

Combo box to select between the output ranges AC 800A, AC 6A, AC 3A, DC 400 A, DC 6 A, AC 2kV, AC 1 kV, AC 500V, AC 130V and CB2:1000A, CB2:2000A or CU20:10A, CU20:20A or CU1:10A, CU1:20A, CU1:50A, CU1:100A

Either CB2:, CU20: or CU1: output ranges are available if the respective external booster was selected at the Options tab Device Setup (see ”Options” on page 2-35) or on the Settings page of the Quick test card.

Each range has an associated minimum and maximum value, a fixed precision value as well as a preset number of decimal characters (refer also to ”Setting Up a Test Card” on page 2-25).

If Quick operates in the "on" state, the output range setting is locked and cannot be changed.

While in the "measuring" state with de-activated outputs, when a range is changed, the output changes accordingly to a new value within the allowed range between minimum and maximum.

After having pressed Keep Results, the output range setting and the measurements settings are locked and cannot be changed.

Power output value

Current (I) or voltage (V) value, depending on the specified range (see above).

Any value between minimum and maximum as well as the explicit value 0.0 is possible, even while in the "on" state.

The respective minimum and maximum values depend on the range and, for voltage ranges, also on the frequency. For frequencies smaller than 50 Hz, and down to the minimum frequency of 15 Hz, the possible maximum voltage value decreases linear proportional to the frequency value (refer to Figure 3, ”Typical maximum output voltage of 2kV AC output depending on frequency and power” on page 14-13).

Current ranges do not have such a dependency.

Frequency / Phase angle

Frequency value in Hz or - if "Sync w/ V1AC" is selected (see below) - phase angle in degrees. For DC ranges this data entry field is disabled.

The frequency can be set within a range of

15.00 … 400.00 Hz, even while in the "on" state.

The phase angle is displayed in a range of

-180.0 … +180.0°, and can also be changed at any time. If this range is exceeded, the phase angle will adapt itself automatically, that is, change from

-180.0 to +180.0°.

Sync w/ V1AC

Set Sync w/ V1AC 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. 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 (we recommend a minimum input voltage of 10 V on V1 AC, possible range 48 - 62 Hz).

The icon next to the frequency/ phase angle data entry field reflects the actual setting.

If "Sync w/ V1AC" is disabled, the frequency returns to the previously set frequency value and the icon changes.

If Quick operates in the "on" state, the status of "Sync w/ V1AC" cannot be changed.

Note: Due to the PLL (phase-locked loop) technology, the synchronization with V1 AC needs about 100 ms.

If for the particular test object the synchronism within the first 100 ms is relevant, start with a reduced magnitude of the output signal. Then enter the full magnitude of your choice, and press Enter.

This procedure assures that the high-level output signal is synchronized with V1 AC right from the beginning.

Trigger Settings

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.

Trigger on:

Selection of trigger event

• no trigger (default)

• binary trigger = CPC 100 input BIN IN is monitored for a trigger event

• trigger = first measurement value (m1) > set threshold value

• trigger = first measurement value (m1) < set threshold value

• trigger = second measurement value (m2) > set threshold value

• trigger = second measurement value (m2) < set threshold value

• overload = the trigger event is an overload condition that occurs at the selected output.

What is an "Overload" trigger?

3 - 10

At the 800A AC output, an overload trigger is a condition in which the set current cannot be reached any longer, for example, because of an opening contact or circuit breaker.

Note: Current values current circuit opens. Therefore, if you use the trigger condition "Overload", choose a nominal current value of

Quick differentiates two "Overload" trigger conditions:

1.the occurrence of an overload (as described above)

2.the clearing of an overload condition (clearing is delayed by 100 ms to debounce).

 50 A do not initiate an "Overload" when the

 50 A.

Page 93

Getting Started with Quick

Note: Trigger conditions with "<" are meaningful in combination with external signals only, that is, with signals that are not coming from the

CPC 100. Reason: if the trigger signal comes from the CPC 100, the trigger

condition will always be "true" at the moment the I/O (test start / stop) push-button is pressed.

After having pressed Keep Results, the trigger event is locked and cannot be changed.

Data entry field for the threshold value.

Setting a threshold value is not possible ("n/ a", as shown above), if either

• a binary trigger condition

•no trigger

•overload

was selected.

After having pressed Keep Results, data entry for the threshold value is disabled, that is, the value cannot be changed.

Bin.In:

Indicates the signal condition at the binary input Bin In. 4 different characteristics are possible:

Closed: potential-free contact between BinIn+ and BinIn– closed.

Open: potential-free contact between BinIn + and BinIn – open.

Come:

trigger signal with rising edge occurred at BinIn.

Go:

trigger signal with falling edge occurred at Bin In

Delay time display

The delay time is the time between the last change of the CPC 100

output value and the occurrence of the trigger event.

3 - 11

Page 94

CPC 100 V 1.44

Switch off on trigger

This option is available if the trigger condition is either binary or overload. Else, "switch off on trigger" is preset and cannot be disabled.

"Switch off on trigger" is also locked and cannot be changed after having pressed Keep Results.

1. Enabled

When the trigger event occurs, the CPC 100 outputs are

switched off immediately (that is, in real-time).

The measurements are updated to show the values at the time the trigger event occurred, and are then "frozen", that is, not updated anymore from that moment on. Quick turns to the "off" state.

At the field for the power output value setting, the data entry mode is automatically disabled to prevent this value from being changed. The focus, however, remains on that field, enabling instant navigation with the handwheel.

Pressing the menu key Keep Results saves the measured values in the measurement table. Quick returns to the "measuring" state, the measurement continues in a new line of the measurement table.

2. Disabled

The CPC 100 outputs remain active, that is, in "on"

state, after the trigger event occurred. If the trigger is binary, the "BinIn" indicator reflects the occurrence of the trigger event accordingly.

The focus remains in data entry mode on the field for the power output value setting, allowing an immediate change of the output value.

The measurements continue after the trigger event.

As soon as the output value is changed, the display of the most recent delay time is removed.

CTRatio (and Burden)

Testing Ratio, Polarity (and Burden) with Injection to Current Input

Use the CTRatio test card to measure a current transformer’s ratio and burden with injection on the CT’s primary side with up to 800 A from the 800A ACoutput

or up to 2000 A using the CP CB2 current booster connected to the "EXT.

BOOSTER" output.

It measures amplitude and phase angle of the current (at IAC) and voltage (at V1 AC) on the transformer’s secondary side, and calculates the actual ratio and the deviation from the nominal ratio.

Current Transformer

Three methods to determine I sec

The secondary current Isec can be determined either

1. by leading it directly via the 10A current input IAC (refer to Figure 2 on page

4-3), and let the CPC 100 measure it.

2. by means of a current clamp that is connected, for example, to the V2 AC low-level AC voltage measuring input (refer to ”Testing Ratio, Polarity (and Burden) with a Current Clamp” on page 10 of this chapter).

3. by selecting the check box Manual input. This option lets you enter the value for I sec manually, for example, when I sec was measured with an external

current clamp that is not connected to the CPC 100.

Note: Select Manual input prior to starting the test. If the test card still contains results, clear them by pressing Clear Results. When Manual input is selected, there is no phase available. Consequently, the polarity and cos

 cannot be calculated.

Measurements

Iprim: actual current output at the 800 A AC output that is injected into

the CT’s primary side

Isec:

measured secondary current and phase angle

 relative to

Iprim

Ratio:

ratio Iprim /Isec., here 200:5.0133

and deviation of current ratio in %.

((Kn x Isec - I prim) / Iprim) x 100%

((200A / 5A * 5.013 A - 199.99A) / 199.99A) x 100 % = + 0.265%

Polarity: displays the status of the polarity

OK = phaseIsec - phaseIprim = - 45 °< 0° < +45°

NOT OK = all other cases

1. The value 5.0133 is calculated as follows: Isec act x (Iprim nom / Iprim act); here: 5.013 A x (200A / 199.99A) = 5.0133

2. Kn = rated transformation value, here: 200A / 5A
