The synchrocheck function and its permission to close is a condition in the present exercise to allow the recloser to give the
different programmed shots. Should not this condition be required these settings are non relevant, but if does like in the
present case the synchrocheck function must be set as follows
The programmed operation of a TOC protection with reclosing and synchrocheck features for the F650 relay is shown in .
Some conclusions follows:
The recloser cycle ends at lockout status since a permanent fault remains after two unsuccessful reclosing trials.
The holding time for reclosing conditions can be very low since the processor internal time to check them is instantaneously
if they are present at this moment. Depending in the application reclosing conditions might come later especially when
commands are sent from dispatching center. If does then this timing must be set properly.
