Restoring

Maintenance is very important to improve the availability of the protection system by
detecting failures before the protection is required to operate. There is however little
point in testing healthy equipment and then putting it back into service with an open
terminal, with a removed fuse or open miniature circuit breaker with an open
connection, wrong setting, and so on.

Thus a list should be prepared of all items disturbed during test so that all can be put
back into service quickly and without overlooking something. It should be put back
into service item by item and signed by the responsible engineer.
