1MRK 505 268-UUS A
1. Check that the autorecloser function SMBRREC (79) is operative, for example, by making a
reclosing shot without the INHIBIT signal.
2. Apply a fault and thereby a RI signal. At the same time, or during the open time, apply a signal
to the input INHIBIT.
3. Check that the reclosing sequence is interrupted and no reclosing takes place.
Check closing onto a fault
1. Check that the autorecloser function SMBRREC (79) is operative, for example by making a
reclosing shot.
Keep the CBREADY signal high.
2. Set the breaker simulating relay BR in Open position.
3. Close the BR relay and apply immediately a fault and thereby a RI signal.
4. Check that no reclosing takes place.
Checking the influence of CB not ready for reclosing
1. Check that the autorecloser function SMBRREC (79) is operative, for example by making a
reclosing shot.
Keep the CB simulator BR closed. Remove the CBREADY signal by opening SRY.
2. Apply a fault and thereby a RI signal.
3. Check that no reclosing takes place.
Checking the influence of synchronizing check (at three-pole reclosing)
1. Check that the autorecloser function SMBRREC (79) is operative, for example, by making a
three-pole reclosing shot with the synchronizing check condition.
Remove the SMBRREC (79) signal.
2. Apply a fault causing three-phase trip and thereby a RI signal.
3. Wait for the
Check that no reclosing is made.
Restoring equipment
After the tests, restore the equipment to normal or desired state. Check the following items in
particular:
1. Check the operation counters.
Reset the counters to zero, if that is the user's preference. The counter reset function is
found on the local HMI under Main menu/Clear/Clear counters/SMBRREC(79,0->1)
2. Restore settings that may have been modified for the tests back to normal.
3. Disconnect the test switch, CB simulating arrangement and test circuits.
Reconnect any links or connection terminals, which may have been opened for the tests.
4. Reset indications, alarms and disturbance recordings.
Clearing of the disturbance report must be done via the Disturbance Handling in PCM600.
