1.
Apply a single-phase voltage 100%
UBase
to the U-Bus, and a single-phase
voltage 30%
UBase
to the U-Line.
2.
Check that the AUTOENOK and MANENOK outputs are activated.
3.
Increase the U-Line to 60%
UBase
and U-Bus to be equal to 100%
UBase
.
The outputs should not be activated.
4.
The test can be repeated with different values on the U-Bus and the U-Line.
Testing the dead bus live line (DBLL)
The test should verify that the energizing check function operates for a low voltage
on the U-Bus and for a high voltage on the U-Line. This corresponds to an
energizing of a dead bus to a live line.
1.
Verify the local HMI settings
AutoEnerg
or
ManEnerg
to be
DBLL
.
2.
Apply a single-phase voltage of 30%
UBase
to the U-Bus and a single-phase
voltage of 100%
UBase
to the U-Line.
3.
Check that the AUTOENOK and MANENOK outputs are activated.
4.
Decrease the U-Line to 60%
UBase
and keep the U-Bus equal to 30%
UBase
.
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%
UBase
to the U-Line and a single-phase
voltage of 100%
UBase
to the U-Bus.
3.
Check that the AUTOENOK and MANENOK outputs are activated.
4.
Change the connection so that the U-Line is equal to100%
UBase
and the U-
Bus is equal to 30%
UBase
. 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%
UBase
to the U-Bus and a single-phase
voltage of 30%
UBase
to the U-Line.
4.
Check that the MANENOK output is activated.
5.
Increase the U-Bus to 80%
UBase
and keep the U-Line equal to 30%
UBase
.
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.
