1. Repeat the above test steps 1 to 2.
2. Set
tEnergy
setting as 1 minute and supply the IED with three phase currents and
voltages at their rated value till 1 minute.
3. Ensure that the active and reactive energy values are less than the
EALim
and
ERLim
setting default values respectively.
4. Check that
EAFALM
and
ERFALM
are low.
5. Increase the supply currents or voltage in next 1 minute cycle such that the active
or reactive energy values are greater than the
EALim
and
ERLim
setting default
values respectively.
6. Check that
EAFALM
and
ERFALM
are high after 1 minute.
7. Similarly the testing can be done for
EARALM
and
ERRALM
outputs by changing
the power inputs directions through direction settings.
12.13.2.2
Completing the test
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.

Station communication
12.14.1
Multiple command and transmit MULTICMDRCV /
MULTICMDSND
The multiple command and transmit function (MULTICMDRCV /
MULTICMDSND) is only applicable for horizontal communication.
Test of the multiple command function block and multiple transmit is recommended
to be performed in a system, that is, either in a complete delivery system as an
acceptance test (FAT/SAT) or as parts of that system, because the command function
blocks are connected in a delivery-specific way between bays and the station level and
transmit.
Command and transmit function blocks included in the operation of different built-in
functions must be tested at the same time as their corresponding functions.
