3 Using the Converter

The ABB REF615 XRIO converter can be used as a stand-alone converter or in association with a relayspecific test template, for example with the OMICRON Feeder Protectiontemplate for the ABB REF615relay.

In any way the converter is used, follow the quick start instructions and create your test by using

LinkToXRIO or start using the relay specific test template (for more information, see the test templatedocumentation).

4 Required Software Version

To use this converter, you must have a valid license for the OMICRON Test Universe2.22 software.

5 Functional Range

The ABB REF615 XRIO converter implements the following functions:

Three-phase non-directional overcurrent (PHIPTOC1 / PHHPTOC1 / PHHPTOC2 / PHLPTOC1) Three-phase thermal overload (T1PTTR1)

Non-directional earth-fault (EFHPTOC1)

Directional earth-fault (DEFHPDEF1 / DEFLPDEF1 / DEFLPDEF2)

Negative phase-sequence current protection (NSPTOC1 / NSPTOC2)

Phase discontinuity (PDNSPTOC1)

Figure 2: Functional range of the ABB REF615 XRIO converter


5/11



Some of the functions listed above use the RIO interface of the Test Universesoftware. Consequently, thetest modules are configured automatically without using LinkToXRIO.

The following functions are using the RIO interface:

Three-phase non-directional overcurrent (PHHPTOC1 / PHHPTOC2 / PHLPTOC1)

Three-phase thermal overload (T1PTTR1)




For testing the other functions, you must use LinkToXRIO.

6 Not Supported Functions

The following functions are currently not supported:

Setting the group change options Three-phase inrush detector (INRPHAR)

Intermittent earth-fault protection (INTRPTEF)

Circuit breaker failure protection (CCBRBRF)

Auto recloser (DARREC)

Arc protection (ARCSARC)

Although these functions are not supported, their setting values are available in the Relay ParameterSection.

7 OMICRON Test Strategy

The OMICRON test strategy is described in the OMICRON Protection Test Template(PTT) FeederProtectiondocumentation. For detailed information, see the PTT Feeder Protectiondocumentation for theABB REF615.

8 Converter Structure

The converter is divided into two sections: the ABB REF615 section and the RIO section. Both sectionsconsist of several function blocks.

8.1 ABB REF615 Section

The Relay Parameter Sectionincludes parameters which can be changed by the user. All relayparameters are included in this section and can be set to the actual relay values.

8.1.1 Relay Parameter Section Block

Setting parameters are included in this block. The parameters are grouped and named as in the ABBPCM600 Version 2.0 software. Each parameter in this block can be identified by its Parameter Name,which is identical to the parameter name in the PCM600 software.

Figure 3: Setting the parameters in the Relay Parameter Section

8.1.2 Additional Information

This block has been added for relay specific parameters such as tolerances which cannot be set by theuser, because they are constant values. All values set in this block can be found in the chapter "TechnicalData" of the relay's documentation. Typically, these blocks do not have to be changed (except theGeneral Information, Circuit Breaker Informationand Test Configuration), as they are already set to thevalues given in the user manual of the relay.


7/11



Figure 4: Setting general information

The parameters contained in the General Information block are linked to the device part of the RIOsection and are available in the test report.

Note:Depending on which relay output contacts are used for routing the trip and start signals for testing,the corresponding pulse time of the output should be entered in the parameter Pulse time(blockAdditional Information / Test Configuration / Generic Timer). See the relay documentation for moreinformation.

Figure 5: Pulse time parameter for relay output contacts

8.1.3 Template Controller (Advanced view)

The Template Controllerblock contains special values which are needed for some tests, especially fortests by using LinkToXRIO. These are mainly calculated values which cannot be calculated by usingLinkToXRIO and therefore have to be stored in this section. Other values needed for customer designedtests can be stored in this block.


8/11



8.1.4 RIOPlus (Advanced view)

The RIOplusblock contains the interface, which provides the link between the XRIO converter and all testmodules which have no access to RIO functions. All tests using basic test modules like Rampingor StateSequencerhave to be linked to the parameters in the RIOplus section of the converter.

8.1.4.1 NamePlate

The NamePlateblock contains all necessary information to identify the protection device to be tested. Thisblock contains the relay vendor, serial number, model, the relay location and a description.

8.1.4.2 PowerSystemParameters

The number of phases, phase rotation and the nominal frequency are stored in this block.

8.1.4.3 Overcurrent Protection 1

This block contains all necessary data to test the protection functions that are based on the evaluation ofthe phase currents. The nominal values and CT settings, used by these protection functions, can be found

here. All protection functions based on phase overcurrent in the relay are modeled as sub blocks of theovercurrent protection 1 block. Each function sub block stores information about the supervised current,pickup value, operating time, pickup-drop off ratio and the curve type of the modeled protection function.The modeled functions in this block are:

Three-phase non-directional overcurrent, instantaneous stage (PHIPTOC1)

Three-phase non-directional overcurrent, high stages (PHHPTOC1 / PHHPTOC2)

Three-phase non-directional overcurrent, low stage (PHLPTOC1)




Phase discontinuity (PDNSPTOC1)

8.1.4.4 Sensitive Directional Earth Fault Protection 1

This block contains all necessary data to test the directional earth-fault protection (measured neutralcurrent). The nominal values and neutral CT / residual VT settings used by this protection function can befound here. All stages of the directional earth-fault protection function (DEFxPDEFx) in the relay aremodeled as sub blocks of the sensitive directional earth fault protection 1 block. Each stage sub blockstores information about the directional element, current pickup value, voltage start value, operating time,pickup-drop off ratio and the curve type of the modeled earth-fault stage.

8.2 RIO

The RIOsection of the converter contains all specialized RIO functions which are needed to use the morespecialized test modules (like Overcurrent) provided by the OMICRON Test Universesoftware.

Warning:Do not change any values in this section. The values have been set using the relay settings ofthe Relay Parameter Section.

Note:Do not activate the former test object view in the advanced mode of the XRIO test object. Changingparameters in this view could disable formulas in the RIO section.

The ABB REF615 converter constructs the overcurrent characteristic curve out of the setting values in theRelay Parameter Section which allows using the test modules listed above for testing the relay functions.


9/11



8.2.1 Phase Overcurrent (PHLPTOC1, PHHPTOCx)

This RIO function provides all necessary values for testing the following protection functions with the TestUniverseOvercurrenttest module:

Three-phase non-directional overcurrent, high stages (PHHPTOC1 / PHHPTOC2)

Three-phase non-directional overcurrent, low stage (PHLPTOC1)

The ABB REF615 XRIO converter constructs a resulting characteristic curve. The three stages arecombined and the resulting characteristic curve is shown in the RIO overcurrent function block.

8.2.2 Thermal Overload (T1PTTR1)



The module contains the thermal overload characteristic curve.

8.2.3 NonDir EarthFault (EFHPTOC1)



8.2.4 Directional EarthFault (DEFxPDEFx)



The following RIO functions for testing these protection functions are available:

Earth-Fault forward direction

Earth-Fault reverse direction

The ABB REF615 XRIO converter constructs a resulting characteristic curve for each direction of theearth-fault elements. This means that directional and non-directional stages are compared for forward andreverse direction. The three stages are combined and the resulting characteristic curve is shown in theRIO overcurrent function block. Non-directional stages will be considered for both forward and reversedirections.

8.2.5 Negative Sequence (NSPTOCx)



The two negative sequence overcurrent stages are shown as a resulting characteristic curve in the RIOovercurrent function.


10/11



8.3 Activating the RIO functions

The RIO functions have to be set to active manually in each Overcurrenttest module if the converter isused in the stand-alone mode. Activate the corresponding RIO function you intend to use in the localtestobject as shown bellow.

Figure 6: Activating a RIO function

8.4 Specific Features

This section deals with special requirements of some of the converter functions. Functions not listed herehave no known limitations to their functionalities.

8.4.1 Not-Supported Parameters

Changing of the relay parameter setting Sensor available(T1PTTR1 function) is not supported. Thissetting was fixed to Falsein the converter and changing of it will lead to malfunction of the thermaloverload test.

The converter doesnt support the Operating curve type"RD type".

The setting Minimum operate timefor the IDMT stages is not taken in consideration to construct theovercurrent characteristics.

8.4.2 CT / VT Amplitude Corrections

The settings Amplitude correctionfor voltage and current transformers are not considered in theconverter. If they have values different than 1, adaptations in the CMC Voltage and Current Outputconfiguration are necessary for testing. For more information, see the ABB REF615 Feeder ProtectionTest Template user manual.

8.4.3 Phase Overcurrent (PHLPTOC1, PHHPTOCx) testing

For the successful phase overcurrent testing with the REF615 converter, it is allowed to set only one

stage as IDMT. The other stages should be set to DMT (ANSI Def. Time or IEC Def. Time). The IDMTstage must have the lowest pickup value!


11/11



8.4.4 Directional Earth Fault Forward/Reverse (DEFxPDEFx) testing

Only one of the directional earth-fault stages in each directioncan have an IDMT characteristic whichmust have the smallest pickup value. The others must have a definite time characteristic (ANSI Def. Timeor IEC Def. Time).

The setting Min operate currentis not considered by the converter. If this parameter has a higher value

than the current Start value, it may lead to malfunctions in case of directional stages (forward or reverse).

8.4.5 Negative Sequence (NSPTOCx) testing

For the successful negative sequence testing with the REF615 converter, it is allowed to set only onestage as IDMT. The other stage should be set to DMT (ANSI Def. Time or IEC Def. Time). The IDMTstage must have the lowest pickup value!
