9424200994 Rev N 373Protection and Control Function VerificationBefore placing the BE1-11g in service, the user should ensure that all system ac and dc connections arecorrect, that the BE1-11g functions as intended with user settings applied, and that all equipment externalto the BE1-11g operates as intended. All connected or monitored inputs and outputs, and polarity andphase rotation of ac connections should be tested. Verify that:• Power supply voltages and contact wetting voltages are correct.• User desired protection and control functions are enabled and connected to the correct CT andVT input circuits.• The programmable logic settings (electronic wiring) provide the proper interconnection of thesefunctions with the I/O of the BE1-11g.Simple user-designed fault tests should be used to verify that the operational settings are correct, that theproper output relays are actuated and proper targeting occurs. It is not necessary to test every protectionelement, timer, and function in these tests.Use of the fault and event recording capability of the BE1-11g will aid in the verification of the protectionand control logic. Use the Metering Explorer in BESTCOMSPlus to open the Reports, Sequence ofEvents screen. In addition, it is helpful to click on the Clear button prior to starting a test. This allows theuser to review only those operations recorded since the sequence of events was last cleared. Refer to theSequence of Events chapter for more detail.It may be necessary to disable protection elements or change setting logic to verify a specific function. Toguard against placing the BE1-11g in service with unwanted operational or logic settings, it is goodpractice to save a copy of the original setting file before the testing process begins. When testing iscomplete, compare the copy of the saved settings to the actual settings as a final verification.Use the settings compare feature in BESTCOMSPlus to compare setting files. Refer to theBESTCOMSPlus Software chapter for more information.Verify Other Setpoints as AppropriateConsult the individual functional testing chapters for guidelines on testing and verifying setpoints of otherprotection and control functions.Reporting and Alarm FunctionsJust prior to placing the BE1-11g in service, the following reporting and alarm functions should be resetand/or verified.Clock DisplayBESTCOMSPlus Navigation Path: Metering Explorer, Status, Real Time ClockHMI Navigation Path: Metering Explorer, Status, Real Time ClockChapter Reference: TimekeepingSet the real time clock to the current date and time. If an IRIG signal or NTP server is used, day, time,and year are automatically synchronized with the source. Note that the time code signal from older IRIGtime code generating equipment does not contain the current year information thus necessitating theentry of the year.BE1-11g Commissioning Testing
