Software and Hardware Requirements To use this template. General information on the usage of OMICRON Protection Testing Library items can be found in the OMICRON PTL user manual.04 1.1 Supported Relays The following relays can be tested with the Protection Test Template:  7UT633  7UT635 2.6 PTT User Manual 1.61. © OMICRON electronics GmbH 3/6 . you must have a valid test license for the OMICRON Test Universe 3. The template has been tested with the following relay: Manufacturer: SIEMENS Model: 7UT613 MLFB: 7UT61315EB111AA0 Firmware Version: V04.01 software or higher versions and the following test modules:  Control Center  Diff Configuration  Diff Trip Time Characteristic  Diff Operating Characteristic  Diff Harmonic Restraint  Overcurrent  Ramping  State Sequencer Six current outputs are required to use this PTT. With a CMC156 an additional current amplifier is necessary.OMICRON PTL Siemens 7UT613 7UT633 V4. General This user manual describes details of testing 7UT613 and 7UT633 relays with the OMICRON Protection Test Template. These connections are the default settings in the Hardware Configuration of the PTT. Hardware There are multiple possibilities of wiring a 7UT613 or a 7UT633 relay to a CMC test set.6 PTT User Manual 3. The advised connections are shown in Figure 1.

XRIO Converter The Test Object already contains the Siemens 7UT613 and 7UT633 XRIO Converter. substation name etc.81. device type.  VT's includes the VT's parameters.1 General Information section General information section is divided into three sections: General. The setting parameters are built as an image of the DIGSI 4.OMICRON PTL Siemens 7UT613 7UT633 V4. The "Standard Filter for XRIO Files" –import filter can be used for importing settings into the Relay Parameter Section. The block is divided into the following sections: 5.1. © OMICRON electronics GmbH 5/6 .  CT's includes the CT's parameters.1 Additional Information This block contains additional data for testing the Siemens 7UT613/7UT633 relay functionality. the Relay Parameter Section of the XRIO Converter includes all protection parameters of the relay. Functional Range Supported functions:  Differential Protection  Time Overcurrent Protection for Phase and Residual Currents  Time Overcurrent Protection for Earth Current  Thermal Overload Protection Not supported functions:  Restricted Earth Fault Protection  Dynamic Cold Load Pickup for Time Overcurrent Protection  Single-Phase Time Overcurrent Protection  Unbalanced Load Protection  RTD-Boxes for Overload Detection  Overexcitation Protection  Reverse Power Protection  Forward Power Supervision  Undervoltage Protection  Overvoltage Protection  Frequency Protection  Circuit Breaker Failure Protection  External Trip Commands  Monitoring Functions Although the functions listed above are not supported by the Protection Test Template. CT's and VT's. 5. This section includes parameters which have to be changed by the user according to the customer relay type and substation. 5. as the parameters are already set to the values given in the user manual of the relay. Therefore it may be necessary to reset the thermal image after each test shot for a correct display of the tripping characteristic. are described.1 Diff Harmonics Blocking Test The Diff Harmonic Restraint test module is used for checking the correct relay behavior of the harmonic restraint of the differential protection.c This block has been added for circuit breaker information.1. these blocks don't have to be changed.  Reference Leg: The reference side of the transformer. Three currents are required for this test.3 Circuit Breaker Information Leg a . 6. because important test values are calculated on the basis of the transformer information. 5. 5.2 Relay Information section This block has been added for relay specific parameters. used in in-rush and over-fluxing/over-excitation relay functions. For the test a search line is placed at Idiff = 1.or three-winding transformer (this setting is linked and shouldn't be set by the user). This information is crucial for testing transformer differential relays. This section includes parameters which have to be changed by the user according to the customer power system. For the 7UT613/7UT633 relays.1.OMICRON PTL Siemens 7UT613 7UT633 V4.1. 6.5 Transformer Information Additionally. typically the high-voltage side 6. Typically.  The sections include all tolerances that can be found in the 7UT613/7UT633 relay manual.6 PTT User Manual 5. which are not covered by the OMICRON PTT User Manual. for example. Notice: Additional search lines can be added by the user.2 Thermal Overload This function is often depending on a thermal image with additional restart inhabitation. Specific Protection Tests In this chapter the specific protection tests. which is carried out on the reference winding side. 5. © OMICRON electronics GmbH 6/6 . the Transformer Information subblock contains transformer information needed for testing. the following transformer data has to be set prior to testing:  Number of Legs: States whether the protection object is a two.5 × Iref.4 Test Tolerance This Block includes the information of the test tolerance.1.
