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.
Check the
MAXPAFD
and
MAXPRFD
outputs after 1 minute and compare it with last 1 minute
average power values.
4. Increase either three phase current or voltage above the last 1 minute value.
5. After 1 minute check the
MAXPAFD
and
MAXPRFD
whether it is showing the last 1 minute
average power value as maximum.
6. Next 1 minute cycle reduce the current or voltage below previous value.
7.
Check after 1 minute whether the
MAXPAFD
and
MAXPRFD
outputs are retaining the old
maximum value.
8. Similarly the testing can be done for
MAXPAFD
and
MAXPRFD
outputs by changing the
power inputs directions through direction settings.
Verification of EAFALM & ERFALM outputs
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
M13906-301 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.

Station communication
SEMOD53595-1 v1
12.14.1
Multiple command and transmit MULTICMDRCV /
MULTICMDSND
SEMOD172432-5 v3
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.
