7 OMICRON Test Strategy The OMICRON test strategy is described in the OMICRON Protection Test Template (PTT) Generator documentation. For detailed information, see the PTT Generator documentation.

8 Converter Structure The converter is divided into two sections: the P34x section and the RIO section. Both sections consist of several function blocks. The converter comes up in the standard view; the RIOplus section and the template controller section can only be seen in the advanced view.

8.1 P34x Section The P34x section is divided into four groups: the Relay Parameter Section, the Additional Information section, the RIO Plus section and the TemplateController section.

8.1.1 Relay Parameter Section The Relay Parameter Section includes the parameters which have to be changed by the user. All relay parameters are included in this section and have to be set to the actual relay values. The parameters are grouped and named as in the AREVA MiCOM S1 Studio software. Each parameter in this block is identified by a Foreign ID (witch corresponds to the Address in the relay software).

8.1.2 Additional Information This block contains additional data for testing the P34x relay functionality. The block is divided into the following sections: General section – includes detailed information needed for the test report like manufacturer, device type, substation name etc. This section includes parameters which have to be changed by the user according to the customer relay type and substation. Relay Information section - This block has been added for relay specific parameters such as tolerances which cannot be set by the user, because they are constant values. All values set in this block can be found in the "P34x Generator Protection Relay" manual. Typically, these blocks do not have to be changed, as they are already set to the values given in the user manual of the relay. Circuit Breaker Information section – includes information which is required for the CB test. 

Test Tolerance section – includes an additional test tolerance to calculate the start and end value for trip and pickup tests by using the OMICRON TU Ramping module. Test Parameters section – includes additional test parameters for testing adaptive functions witch are not directly supported by the OMICRON TU test modules e.g. a voltage level for the 51V tests. Furthermore it includes additional test parameters which are needed for testing the protection function but not found in the relay settings. e.g. high operating current stage for the 87 Phase Differential protection function. This section includes parameters which have to be changed by the user.
