4.10. Function 79. Autorecloser
The reclosing function recloses the circuit breaker after a fault. It has a five reclosing capacity,
following which the unit shall be Locked or in “Lockout” mode.
The reclose device can be permitted or prohibited, depending on whether or not this function is
required. Prohibited must not be confused with locked. Prohibited means that the recloser shall
never be in operation, regardless of the controls performed on it. A locked recloser means that
the recloser is not operative, but either because it has reached the end of the reclosing cycle, or
a fault has been detected, or someone has performed a control procedure on it.
There is a final permission which serves to indicate that recloser that it must wait a period of time
before closure. In this time, there is usually an external condition, such as closure synchronism,
and this condition in from an external input.
Each reclosing cycle has its own specific operation time that can be set. Apart from these times,
a further three times must be set:
•
Hold times. This is the time the reclosing device waits for an external condition for closure.
•
Replacement time. This is the Hold time for the recloser for a final closure. If during this time,
there is another trip, the recloser count will increase.
•
Final opening time The is the time used by the recloser to declare that the circuit breaker is
finally open. In this case, the recloser understands that the opening was manual or via remote
control, and no reclosing is necessary. On exceeding this time, the recloser shall switch to
locked mode.
