Working Example 1 Introduction

Open the System Settings from the main menu. Display the Application Settings tab and then touch Curve Management.

Curve Management: Adding Application Specific Characteristic Curves for Testing

Inserting the USB memory stick and displaying the test report are described in the CMControl R user manual.

Curve Management

The set of characteristic curves available for testing in the Trip Time Characteristics test tool can be selected in the Curve Management of the CMControl R. Some characteristic curves are delivered together with the CMControl R software. Many more curves can be downloaded from the customer area on the OMICRON web site.

It is furthermore possible to modify existing curves according to your needs by editing the XML file defining the curve using a suitable text editor. For more information, please refer to the user manual.

To transfer new characteristic curves to the CMControl R, copy the curves to the folder \OMICRON\curves on the USB memory stick and connect the USB stick to the CMControl R.

Note: The USB tab of the Curve Management screen can list only the first 20 curves (alphabetical order) stored on your USB memory stick. When preparing your tests, make sure that only relevant curves are stored on the USB stick.

In the Curve Management screen, open the CMControl tab to display a list of all characteristic curves available on the CMControl R. To make the Kyle104 and Kyle114 curves available for testing, highlight the Kyle104 and/or Kyle114 entry in the USB tab and then touch the Add selected button to add the curve to the Available for testing list.


Working Example 2

Trip Time Characteristic Test for Cooper Form 4C, 14 Pin (D1)

This example guides you through the process of testing a recloser with the CMControl R. Connect the CMControl R and proceed as described in the following subsections.

The following adjustments have to be done to the Kyle Form 4C recloser control:Non-reclosing mode is activeGround trip normal is active

The following parameters are used in this example:TCC #1 is the Kyle111 curveThe device goes into lockout after 3 shotsMinimum trip current for phase-ground faults: 140 A

We will test the characteristic curve for phase-ground faults.

Introduction


Required test steps:1. Selecting the manufacturer and cable2. Defining the hardware configuration3. Performing the wiring check4. Performing the characteristic test (manual testing in trip only

mode)

1. Selecting the Manufacturer & Cable

After switching on the CMC test set and powering-up the CMControl R, the user has to choose the correct cable and manufacturer. This saves a lot of time since the hardware configura-tion is then preset with many necessary values.

Check the hardware configuration if all settings are set correctly according to your recloser control.

2. Hardware Configuration


In the Analog Output Check test tool the currents of the three phases are set to unsymmetrical values by default. Injecting these analog values allows for checking the correct wiring of your har-ness. You can check the magnitudes by using the metering function of your recloser control.Select the Analog Output Check test tool from the main menu.Start the wiring check by pressing the I/0 key. This activates the

outputs of the CMC test set and injects the currents to your recloser control. The red frame indicates that the outputs of your CMC are active. Do not connect or disconnect the device while outputs are active.

Read the values measured by the recloser control and compare them with the output values displayed in the Analog Output Check tool.

Press the I/0 key to stop the wiring check and deactivate the CMC outputs.

3. Wiring Check

The breaker model must be active since the status of the circuit breaker is monitored by the recloser control.

Leave the hardware configuration by touching the Finished button.

For example, you could adjust the setting for I max CMC output in the Currents screen to limit the maximum current output to your device.


Before opening the Trip Time Characteristics test tool, the characteristic curve used for the test must be made available for testing. To do so, open the System Settings from the main menu and navigate to the Curve Management screen. Add the Kyle111 curve to the Available for testing list.Please refer to working example 1 for more information.

Open the Trip Time Characteristics test tool. This test tool is used to test the characteristic curves of TCC elements. In our example we want to examine TCC#1, which is set to be Kyle111.

In the first screen of the test tool, select the Trip Time Test Only application mode (trip only mode).

In the Curves screen select the Kyle111 curve (according to the TCC #1 setting of your device under test) and set the I pick-up value to 140 A. If no curves are available for the test, refer to working example 1 for information on how to add a characteristic curve for testing.

In the Prefault screen set the prefault values as shown in the figure above.

4. Trip Time Characteristic Test (Manual Testing in Trip Only Mode)


In the Test Points screen accept the Manual setting and touch Test to proceed to the test screen of the Trip Time Characteristics test tool.

In the Fault screen select a phase-ground fault type to be simulated by the CMC test set. The Phase angle and Fault volt-age % V nom fields are inactive since the usage of voltages is deactivated in the hardware configuration.

The Trip Time Characteristics test screen is displayed. Press the I/0 key to start the test sequence.

First, a load state is applied using the prefault settings. Then, the fault state on phase A-N is applied. The CMControl R

expects the recloser control to trip during the fault state. As soon as the trip signal occurs, the outputs are switched off

until the Pause time set in the Curves screen expires. During the off state you can change the fault current (I test) using the control wheel or the numpad. The pause time should be set long enough to allow for manual adjustment of the fault current during the dead time.

After the pause time has expired, the new fault current is applied during the next fault state.

You can apply as many test shots as required to determine whether the TCC#1 parameter in your recloser control works correctly.


Press the I/0 key to stop the test sequence after all necessary test shots have been applied.

Each test shot is marked by a cross and assessed using the nominal characteristics curve. If the shot is within the tolerance, the cross is displayed in green. In case of a trip outside of the tolerance the cross is displayed in red.

If no tripping occurs although tripping is expected, the test is terminated and an orange arrow indicates that the maximum fault time expired.

Depending on your report settings the test results are saved automatically or on user request. The report settings must be filled properly in the Report Information submenu of the hardware configuration.

If not performed automatically, save your test results now.

Working Example 3 Introduction

Pick-Up/Drop-Off and Sequence Logic Test for Cooper Form 6, 19 Pin (C1)



Required test steps:1. Selecting the manufacturer and cable2. Defining the hardware configuration3. Performing the wiring check4. Performing the pick-up/drop-off test (current threshold)5. Performing the sequence logic test using the Tripping Sequence

test tool



Select Cooper Form 6 from the Manufacturer drop-down list.

Then select 19 Pin (C1) from the Cable drop-down list and touch Apply to proceed to the hardware configuration.


The figure above shows the hardware configuration settings after selecting the manufacturer and the cable.

For our example we have to adjust some of these settings.


At Voltages switch on the output of voltages. Select the 3 x 300 V output configuration and select that the voltage transformer is installed on the source side.

V max (L-L) CMC output limits the output voltage in order to protect your device under test. The maximum output voltage of the CMC test set is 300 V.

Adjust the VT ratio to 14.4 kV (primary) / 120 V (secondary).

Open the Currents screen to check if the current configuration settings are correct.

Check whether the I max CMC output is set to the correct limit in order to protect your device under test. The maximum output current depends on the CMC test set used (32 A or 12.5 A).

Check whether the CT ratio is set to 1000 A (primary) / 1.0 A (secondary).

The Nominal Values are the basis for the default values offered in the test modules later.

Set the nominal voltage, the current for normal load conditions and the nominal frequency. Select the CT star point polarity.

The VT and CT ratios selected in the voltage and current configura-tions are displayed in read-only fields.


The Device Settings and Phase Rotation settings should be correct, but can be changed if required. Refer to the user manual for more information.

At Report Information you can enter general information about the recloser under test and the tester. The information given here is included in the HTML test report created at the end of each test step.

Switch on and adjust the Aux DC voltage if required. Refer to the user manual for more information.

At Binary Outputs you can select if you want to simulate the breaker status, which will be needed for the ARC sequence later on. You can also adjust the timing behavior of the breaker.

The Binary Inputs assignments should be correct by default according to the cable selected.



outputs of the CMC test set and injects the currents to your recloser control. The red frame of the test tool indicates that the outputs of your CMC are active. Do not connect or disconnect the device while outputs are active.


Press the I/0 key to switch off the CMC outputs.

3. Wiring Check

In the Analog Output Check test tool you can switch between the table view and the vector view or between secondary or primary values and seconds or cycles. Refer to the figures on the next page.


Vector view of the Analog Output Check test tool. Switching between primary or secondary values or seconds or cycles in the Analog Output Check test tool.

Open the Pick-Up/Drop-Off test tool from the main menu. This test tool allows for testing the current pick-up value, the undervolt-age threshold or the underfrequency threshold of the recloser control.

In this example we are going to test the current pick-up value. Therefore, select Current Pick-Up in the Signal Mapping & Function screen.

As many other devices, the Cooper F6 has LEDs indicating the pick-up at the minimum trip current. With the help of a scanning head accessory from OMICRON it is possible to detect the status of this LED. The scanning head transforms the optical LED indication to an electrical signal for the binary inputs of the CMC test set. This way it is possible to accurately measure the threshold of the minimum trip current.

If the LED on the device is not bright enough or if there is no LED available on the front panel of the recloser control, the user can indicate the occurrence of the minimum trip current by touching a button on the CMControl R screen during the test.

A third way to measure the pick-up signal is to establish a direct wiring from a corresponding contact of the recloser control to a binary input of the CMC test set as it is usually the case with protection devices.

In this example we are using a scanning head. Therefore, enable the Use scanning head option. The CMControl R automatically assigns the scanning head to binary input 2.

4. Pick-Up/Drop-Off Test for Current Threshold Determination


In this example we want to test a phase-ground fault. Therefore, select the A-N fault type in the Fault screen.

Fault conditions often cause a voltage drop during the fault state. In order to obtain real and physically correct conditions, set the fault voltage to 75 % of the nominal voltage.

In the test screen of the Pick-Up/Drop-Off test tool select an I test magnitude and angle below the expected pick-up current value. Press the I/0 key on the CMControl R and use the control wheel to increase the test current until the pick-up current is reached. As soon as the pick-up occurs, decrease the current until the recloser drops off. Press the I/0 key again to stop the output. All events are indicated in the event view as soon as they occur.

Open the Tripping Sequence test tool from the main menu. We are going to test the sequence to lockout of the recloser control. Therefore, select the Recloser mode in the Application Mode screen.

5. Sequence Logic Test (Tripping Sequence for Recloser)

In the Load screen enter the Prefault time and the Load angle. During the prefault time, the CMC outputs the load current and the nominal voltage defined in the nominal values with the specified load angle. The Load current is displayed for information.


In this example we want to test a phase-ground fault. Therefore, select the A-N fault type in the Fault screen.


Set the Fault current to 1000 A.

In the Configuration screen select the number of Shots to lockout. According to our example the Cooper F6 recloser control must not send a close command anymore after the occurrence of the third trip signal. Set the Max. dead time and the Max. trip time accordingly. For this, we need to know the maximum trip time of the slower curve for the fault current entered in the Fault screen before. Select the Kind of test to be performed. In this example we are using Full Sequence to Lockout.

Press the I/0 key to start the test sequence. In the test screen of the Tripping Sequence test tool the current state of the CMC outputs is indicated on the left side. The table on the right is filled with measurements during the test.

The test stops automatically when the test sequence is finished.

The times displayed on the right side of the screen can also be displayed in cycles.




Working Example 4

Trip Time Characteristics and Sequence Logic Test for SEL351R, 14 Pin (D1)


The following parameters are used in this example:TCC #1 for phase: 104TCC #2 for phase: 114 I min trip for phase: 200 AThe device locks out after 5 shotsThe last shot on TCC #1 is 2Recloser intervals: 300 cy, 300 cy, 450 cy, 600 cy

We will test the characteristic curve for phase-phase faults and the sequence logic.

Introduction

To save your test results in a test report, insert a USB memory stick to the CMControl R and select the Auto Save option prior to testing.


Required test steps:1. Selecting the manufacturer and cable2. Defining the hardware configuration3. Performing the wiring check4. Performing the characteristic test (using a test sequence in trip /

close mode)5. Performing the sequence logic test using the Tripping Sequence

test tool




The figure above shows the hardware configuration settings after selecting the manufacturer and the cable.

In this example we have to adjust some of these settings.


At Voltages switch on the output of voltages.

V max (L-L) CMC output limits the output voltage in order to protect your device under test. Adjust the voltage accordingly.

The VT ratio of the SEL351R is set to 120:1. Therefore, adjust the VT ratio field to 14.4 kV (primary) / 120 V (secondary).

Enable the Aux DC option to supply the recloser control during the test with 24 VDC.

At Binary Outputs make sure that the Breaker model active option is selected. Otherwise the recloser control cannot be tested properly.

The Nominal Values are the basis for the default values offered in the test modules later.

Set the nominal voltage, the current for normal load conditions and the nominal frequency. Select the CT star point polarity.

The VT and CT ratios selected in the voltage and current configura-tions are displayed in read-only fields.


The hardware configuration should now provide the settings as shown in the figure.



outputs of the CMC test set and injects the currents to your recloser control. The red frame of the test tool indicates that the outputs of your CMC are active. Do not connect or disconnect the device while outputs are active.


Press the I/0 key to deactivate the CMC outputs.

3. Wiring Check

For the SEL351R it is important that the breaker model is active. The breaker symbols in the lower right corner of the CMControl R screen indicate the states of the CB simulation in the CMC test set. Usually, testing does not make sense if the state of the breaker model is open at the beginning. Make sure that the states of the CB simulation comply with the actual states on the recloser control.


Before opening the Trip Time Characteristics test tool, the characteristic curves used for the test must be made available for testing. To do so, open the System Settings from the main menu and navigate to the Curve Management screen. From the USB stick, add the Kyle104 and the Kyle114 curve to the list of curves available for testing.

Open the Trip Time Characteristics test tool. This test tool is used to test the characteristic curves of TCC elements.

In the first screen of the test tool select the Full Sequence to lockout application mode (trip/close mode).

In the Curves screen select Kyle104 for the fast curve and Kyle114 for the slow curve. Set the I pick-up value and the tolerance. The tolerance is important because the trip events are assessed in the final test.

In the Prefault screen set the prefault values as shown in the figure above. The load current and the pick-up current are displayed for information in this screen. During the specified prefault time the load current is applied with the nominal voltage and the specified load angle.

4. Trip Time Characteristic Test (Using a Test Sequence in Trip / Close Mode)


In this example we want to test a 3-phase fault. Therefore, select the A-B-C fault type in the Fault screen.

Fault conditions often cause a voltage drop during the fault state. In order to obtain real and physically correct conditions, set the fault voltage to 70 % of the nominal voltage and the phase angle to -60 .

In the Sequence screen select the Sequence option and set the maximum dead time as shown in the figure.

Set the number of cycles to 5 and adjust the fault currents of the five shots as shown. The CMControl R calculates the expected trip times accordingly and displays the shots in the diagram.

Touch Test to proceed to the test screen of the Trip Time Charac-teristics test tool.

The Trip Time Characteristics test screen is displayed. Press the I/0 key to start the test sequence.

First, the load condition defined in the Prefault screen is applied. Then, the first fault state is applied and the CMControl R waits for

the first trip signal.As soon as the trip signal occurs, the outputs are switched off

and the CMControl R waits for the close signal of the recloser control.

As soon as the close signal occurs, the next fault state is applied, and so on.

In the last cycle (the lockout cycle), the CMControl R does not expect a close signal anymore. An error message is displayed if a close signal occurs during the lockout cycle.

The test stops automatically when the test sequence is com-pleted.


This figure shows the test screen with results of a successful characteristic test.

Due to the fact that the recloser control is in the lockout state, the CB simulation indication in the lower right corner indicates an open breaker state for all three phases.

Open the Tripping Sequence test tool from the main menu. We are going to test the sequence to lockout of the recloser control. Therefore, select the Recloser mode in the Application Mode screen.

5. Sequence Logic Test (Tripping Sequence for Recloser)

In the Load screen, enter the Prefault time and the Load angle. During the prefault time, the CMC outputs the load current and the nominal voltage defined in the nominal values with the specified load angle. The Load current is displayed for information.

In this example we want to test a phase-phase fault. Therefore, select the A-B-C fault type in the Fault screen.


Set the Fault current to 300 A.

In the Configuration screen set the number of Shots to lockout (5), the Max. dead time (800 cy) and the Max. trip time (300 cy).

Select Successful Reclose for the Kind of test. This will display an additional field Cycles to successful reclose. Set this field to 3. This will apply 3 cycles with the fault values before a state with regular load conditions is applied. This way, the recloser control will detect a successful reclose after the third close command and therefore not continue its tripping sequence.


Press the I/0 key to start the test sequence. In the test screen of the Tripping Sequence test tool the current state of the CMC outputs is indicated on the left side. The table on the right is filled with measurements during the test.

The test stops automatically when the test sequence is over.

The right side of the screen can be switched between the cycles view and the event view as shown in the figure above.

Depending on your report settings the test results are saved automatically or on user request.
