1.
Verify the settings
AutoEnerg
or
ManEnerg
to be
DBLL
.
2.
Apply a single-phase voltage of 30%
GblBaseSelBus
to the U-Bus and a single-
phase voltage of 100%
GblBaseSelLine
to the U-Line.
3.
Check that the AUTOENOK and MANENOK outputs are activated after set
tAutoEnerg
respectively
tManEnerg
.
4.
Decrease the U-Line to 60%
GblBaseSelLine
and keep the U-Bus equal to 30%
GblBaseSelBus
. The outputs should not be activated.
5.
The test can be repeated with different values on the U-Bus and the U-Line.
Testing both directions (DLLB or DBLL)
1.
Verify the local HMI settings
AutoEnerg
or
ManEnerg
to be
Both
.
2.
Apply a single-phase voltage of 30%
GblBaseSelLine
to the U-Line and a single-
phase voltage of 100%
GblBaseSelBus
to the U-Bus.
3.
Check that the AUTOENOK and MANENOK outputs are activated after set
tAutoEnerg
respectively
tManEnerg
.
4.
Change the connection so that the U-Line is equal to100%
GblBaseSelLine
and
the U-Bus is equal to 30%
GblBaseSelBus
. The outputs should still be activated.
5.
The test can be repeated with different values on the U-Bus and the U-Line.
Testing the dead bus dead line (DBDL)
The test should verify that the energizing check function operates for a low voltage on
both the U-Bus and the U-Line, that is, closing of the breaker in a non-energized
system. Test is valid only when this function is used.
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.
10.9.1.4
Testing the voltage selection
Testing the voltage selection for single CB arrangements
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.
