1.
Verify the local HMI setting
AutoEnerg to be Off and ManEnerg to be DBLL.
2.
Set the parameter
ManEnergDBDL to On.
3.
Apply a single-phase voltage of 30%
GblBaseSelBus to the U-Bus and a single-phase
voltage of 30%
GblBaseSelLine to the U-Line.
4.
Check that the MANENOK output is activated after set
tManEnerg.
5.
Increase the U-Bus to 80%
GblBaseSelBus and keep the U-Line equal to 30%
GblBaseSelLine. The outputs should not be activated.
6.
Repeat the test with
ManEnerg set to DLLB with different values on the U-Bus and the U-
Line voltage.

Testing the voltage selection
M2377-342 v2
Testing the voltage selection for single CB arrangements
M2377-473 v7
This test should verify that the correct voltage is selected for the measurement in the
SESRSYN function used in a double-bus arrangement. Apply a single-phase voltage of 100%
GblBaseSelLine to the U-Line and a single-phase voltage of 100% GblBaseSelBus to the U-Bus.
If the UB1/2OK inputs for the fuse failure are used, they must be activated, during tests below.
Also verify that deactivation prevents operation and gives an alarm.
1.
Connect the signals above to binary inputs and binary outputs.
2.
Connect the voltage inputs to the analog inputs used for each bus or line depending of
the type of busbar arrangement and verify that correct output signals are generated.
9.6.1.5
Completing the test
M2377-1042 v5
continue to test another function or end the test by changing the
TESTMODE setting to Off.
Restore connections and settings to their original values, if they were changed for testing
purposes.
9.6.2
Autorecloser for 1/2/3-phase operation SMBRREC
M12400-2 v11
Verification of the auto recloser for single-phase, two-phase or three-phase auto reclosing
attempts can be considered to consist of two parts.
•
One part to verify the internal logic and timing of the auto recloser
•
One part to verify its interaction with the protection system
This section deals with verification of the auto recloser itself. However, it is practical to start
the auto recloser by activating a protection function, for example, by secondary injection
tests.
Prepare the IED for verification of settings outlined in Section
.
The purpose of verification before commissioning is to check that entered selections, setting
and configuration render the intended result. The auto recloser is flexible with many options
and facilities. At commissioning only the selections and settings intended for use are verified.
If one chooses to reduce some time settings in order to speed up verification, be careful to set
the auto recloser at intended operational values at the end of the verification procedure. One
such parameter is the
tReclaim time that must be timed out before a new test sequence can
be performed.
The verification test is performed together with protection and trip functions.
