5. Automation functions
5.1. Recloser
5.1.1. General description
The unit enables up to 4 reclosings.
Dierent close times for phase to phase and phase to earth
faults.
In service/out of service push-button in the keyboard.
Programmable security time after manual closing and after
automatic closing.
The 5 closure counters (total, rst, second, third and fourth
closures) are stored in non volatile memory and can be
displayed on the display. These counters can be set to 0 by
keyboard.
Definitions
1. Surveillance or rest status
2. It is the normal status, during which the recloser
“monitors” for the occurrence of any trips and has to
start operating.
3. Ongoing cycle status.
This status of the recloser is set throughout the entire process
in which it is activated from the rst trip up to the closing
of the breaker and the safety period has elapsed (successful
reclosing) or until all the programmed reclosings have been
unsuccessfully executed. In the rst instance it moves on to
“surveillance” and in the second to “denitive trip”.
4. Denitive trip status.
The recloser’s nal situation when it has executed all of the
programmed attempts and the breaker remains open, given
that it is a permanent fault. Exit from this status can only be
achieved by closing the breaker manually.
5. Time for rst, second, third and fourth closure.
It is the waiting time after the breaker’s trip until the recloser
gives the closure order in each of the closure phases.
6. Reclaim time after manual closing.
It is the time from the moment of circuit breaker manual
closing; during this time it is watched if there is a protection
trip, and if this is the case, it will be continued to denitive trip
instead of to surveillance status.
7. Reclaim time after automatic closure.
It is the time from the moment of circuit breaker automatic
closing; during this time it is watched if there is a protection
trip, and if this is the case the cycle will be continued instead
of moving on to surveillance.
8. Close conditions time (optional use).
It is the time margin, after a protection trip, during which
the close conditions (Reference voltage presence) must be
fullled to be able to continue the cycle. It is not used if there
is no input programmed as “reference voltage”.
