4. Increase the voltage slowly until the ULOW signal disappears.
5. Compare the reset value to the set voltage low limit value.
6. Increase the voltage further until the UHIGH signal appears.
7. Compare the voltage value with the set voltage high limit value.
8. Decrease the voltage slowly until the UHIGH signal disappears.
9. Compare the reset value to the set voltage high limit value.
Verifying the circuit breaker operate time setting
tBreaker
GUID-3211FF6E-6BC8-4F65-9C36-29D23B4C1869 v2
1. Supply the IED with rated voltage value.
2. Ensure that the settings in the IED are appropriate, especially the UHighLimit
and ULowLimit settings.
3. Set an appropriate value for the tBreaker setting based on the circuit breaker
characteristics.
4. Activate the START input and wait for the CLOSECB output signal.
5. Check in the captured disturbance file by the IED that the time difference
between the appearance of the CLOSECB output and the voltage peak is
equal to the set tBreaker time.
Verifying the pulse duration (
tPulse
) of output CLOSECB
GUID-5009E500-D4E6-4677-9FEE-E0A8BE067DA5 v2
1. Supply the IED with rated voltage value.
2. Ensure that the settings in the IED are appropriate, especially the UHighLimit,
ULowLimit and tBreaker settings.
3. Set the appropriate value for the tPulse setting based on the circuit breaker
characteristics.
4. Activate the START input and wait for the CLOSECB output signal.
5. Once the CLOSECB output signal appears wait until it disappears.
6. Compare the time between the CLOSECB appearance and disappearance
with the set pulse duration.
10.9.7.2 Completing the test
GUID-E74572D9-68F8-4706-9EC8-B14FB0A80E45 v1
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.
