9424200994 Rev N 491Power (32) TestFunctional testing is a way to assess this protection system’s suitability for your application. Functionaltesting goes beyond the more basic tests found in acceptance testing, but lacks the detailed functiontesting that is part of the commissioning process.Test each of the following functions to verify that this BE1-11g measures accurately, is within specifiedtolerances, and operates correctly. These tests are also suitable for assisting in systematictroubleshooting in the event that an operation is questioned. Revisiting the test of a specific function canhelp verify whether the BE1-11g is operating within specified tolerances. For further assistance, contactBasler Electric, Technical Sales Support.Refer to the Terminals and Connectors chapter for terminal locations and connections.Reset all targets prior to each test by navigating to the Metering > Status > Targets screen and pressingthe front-panel Reset key. Enter the appropriate username and password if prompted. Clear all logic priorto each test by using the Settings Explorer in BESTCOMSPlus® to open the BESTlogic™PlusProgrammable Logic screen and click the Clear button located on the toolbar. After new BESTlogicPlussettings are made, click the Save button located on the toolbar to compile BESTlogicPlus. UploadBESTlogicPlus settings by selecting Upload Logic to Device from the Communication pull-down menu.Operational settings can be sent by selecting Upload Settings to Device from the Communication pull-down menu or by clicking the Send Settings button on the toolbar.The actual operating time of an output contact is equal to the recognition time plus the time delay setting(accuracy) plus 6 milliseconds. Output contact operating time depends upon the type of test set used andits operating characteristics.A Functional Test Report is included at the end of this chapter. It should be used to record the results andverify pickup and timing accuracy.Refer to the Power (32) Protection chapter for more information on this function.Functional Test ProcedureStep 1: Use BESTCOMSPlus to send the operational settings in Table 222 to the BE1-11g. Reset alltargets. Use the same procedure for testing the 32-2 element. There are four enable modes forthe 32 elements 1 of 3, 2 of 3, 3 of 3, and Total Power (Modes 1, 2, 3, and 4). The following testuses Single Phase Tripping (1 of 3) Mode 1. Regardless of mode, the element is set for three-phase power. Single-phase modes automatically operate at the three-phase setting divided bythe appropriate mode. Optionally, the user can test Modes 2, 3, and 4 but they are not shown.Table 222.
