•
Check on the relay that the number of opening operations is 2, and the number of accumulated amperes
is between 5700 and 6400 kA
2
s (exact value 6100) for In(phase) = 5 Amp.
6.27. COMMANDS.
•
The following tasks have to be carried out :
1. Breaker OPENING : Use communications to give a breaker opening command and check that the
breaker opens.
2. Breaker CLOSING. Use communications to give a breaker closing command and check that the breaker
closes.
3. SYNCHRONIZATION. Use communications to synchronize the relay with the date/time on the PC. Check
that the relay is indeed synchronized.
4. DELETE EVENTS. Use communications to erase all the events and check it has been done.
5. BLOCK THE RECLOSER:
- Use communications to block the recloser.
- Close the breaker and wait 10 sec. After this time the recloser is ready to initiate a reclosing cycle
(if it is not blocked).
- Force a trip and check that the relay does not reclose.
6.- UNBLOCK THE RECLOSER:
- With the recloser enabled, issue this command to the relay. This command cancels the previous
one (recloser block).
- Force a trip and check the relay recloses after 2 sec (corresponding to the first programmed
reclose).
6.28. PHASE ROTATION ABC - CBA
•
Set the relay for the phase sequence ABC.
•
Apply the following currents to the relay:
Ia = In (phase) at 0
°
Ib = In (phase) at -120
°
Ic = In (phase) at -240
°
•
Check that the relay reads these values correctly, and I2=0 Amps (negative sequence)
•
Set the relay for phase sequence CBA
•
Check that the relay reads the values correctly, but now I2=In (phase).
6.29. MONITORING TRIP CIRCUITS: UNDERVOLTAGE
(Only for models with expansion board)
COIL 1:
•
Apply nominal minimum voltage (38 Vdc for "A" models and 88 Vdc for "H" models) to the voltage
supervision input for coil 1. Positive is applied to terminal F5 and negative to terminal E6.
•
Check using GE_LOCAL software that the "Coil 1 DC Supply Failure" signal in the internal Status of the
relay is not active.
•
Remove the voltage applied to the above mentioned input.
•
The "Coil 1 DC Supply Failure" signal will become active.
