9. Check the
EAFACC
and
ERFACC
output in the next 1 minute cycle for the
retaining the same value.
10. Activate
STOPACC
input after some time and supply the IED with same current
and voltage.
11. Check that the
ACCINPRG
signal disappears immediately and
EAFACC
and
ERFACC
outputs also stop updating.
12. Similarly the testing can be done for
EAFACC
and
ERFACC
outputs by changing
the power inputs directions through direction settings.
Verification of MAXPAFD & MAXPRFD 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. 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.
10.10.2.2 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.
