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.

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.
