9.11.3.1 Verifying the settings
GUID-962A344D-5F8D-49A6-B3AC-29C7FEED0A3D v4
1. Connect the test set for the injection of a three-phase current to the appropriate
current terminals of the IED.
2. If current need to be injected for a particular test, it should be done in the
phase selected by the PhSel parameter.
3. Follow the sequence for positioning the auxiliary contacts before testing:
POSCLOSE 0 1 0
POSOPEN 0 0 1
4. Test of CB contact travel time
4.1. Test the set timing defined by OpenTimeCorr , CloseTimeCorr ,
tTrOpenAlm and tTrCloseAlm .
4.2. Change the status of the auxiliary contacts such that travel time to open
TTRVOP
and travel time to close
TTRVCL
exceed the respective set
values ( tTrOpenAlm and tTrCloseAlm ). The measured travel time for
opening and closing is shown on
TTRVOP
and
TTRVCL
respectively.
4.3. Check that
TRVTOPAL
and
TRVTCLAL
are activated.
5. Test of CB status
5.1. Test the set current level defined by AccStopCurr .
5.2. Check the
CLOSEPOS
output by changing the POSOPEN to 0 and
POSCLOSE to 1 .
5.3. Check the
OPENPOS
output by changing the POSOPEN to 1 and
POSCLOSE to 0 and also inject the current in the selected phase slightly
lower and higher than AccStopCurr set value. Only for a current lower
than set AccStopCurr should activate the output
POSOPEN
.
5.4. Check the circuit breaker is in
INVDPOS
if auxiliary contacts read same
value or CB is open and inject the current in selected phase more than
AccStopCurr set value.
6. Test of remaining life of CB
6.1. Test the set timing defined by RatedOperCurr , RatedFltCurr ,
OperNoRated , OperNoFault , DirCoef , CBLifeAlmLevel .
6.2. Vary the phase current in the selected phase from below rated operated
current, RatedOperCurr to above rated fault current, RatedFltCurr of a
breaker.
6.3. The remaining life of CB output
CBLIFEPH
is estimated when the CB is
changed from closed to open position. Check that the output
CBLIFEPH
is decreased with a value that corresponds to the injected current.
6.4.
CBLIFEAL
is activated as soon as
CBLIFEPH
is below the set
CBLifeAlmLevel value.
7. Test of accumulated energy
