Protection and Control Function Verification
Before placing the BE1-11g in service, the user should ensure that all system ac and dc connections are
correct, that the BE1-11g functions as intended with user settings applied, and that all equipment external
to the BE1-11g operates as intended. All connected or monitored inputs and outputs, and polarity and
phase 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 and
VT input circuits.
•
The programmable logic settings (electronic wiring) provide the proper interconnection of these
functions 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 the
proper output relays are actuated and proper targeting occurs. It is not necessary to test every protection
element, 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 protection
and control logic. Use the Metering Explorer in BESTCOMSPlus to open the Reports, Sequence of
Events screen. In addition, it is helpful to click on the Clear button prior to starting a test. This allows the
user to review only those operations recorded since the sequence of events was last cleared. Refer to the
Sequence of Events chapter for more detail.
It may be necessary to disable protection elements or change setting logic to verify a specific function. To
guard against placing the BE1-11g in service with unwanted operational or logic settings, it is good
practice to save a copy of the original setting file before the testing process begins. When testing is
complete, 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 the
BESTCOMSPlus Software chapter for more information.
Verify Other Setpoints as Appropriate
Consult the individual functional testing chapters for guidelines on testing and verifying setpoints of other
protection and control functions.
Reporting and Alarm Functions
Just prior to placing the BE1-11g in service, the following reporting and alarm functions should be reset
and/or verified.
Clock Display
BESTCOMSPlus Navigation Path: Metering Explorer, Status, Real Time Clock
HMI Navigation Path: Metering Explorer, Status, Real Time Clock
Chapter Reference: Timekeeping
Set 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 IRIG
time code generating equipment does not contain the current year information thus necessitating the
entry of the year.
