12.2.4.2 Auto recloser settings
The settings for the auto recloser are set using the local HMI (LHMI) or PCM600.
This setting guideline describes the settings of the auto recloser using the LHMI.
The settings for the auto recloser are found under Main menu /Settings /IED Settings /Control /
AutoRecloser(79,5(0->1)) /SMBRREC(79,5(0->)):X and have been divided into four different setting
groups: General, CircuitBreaker, DeadTime and MasterSlave.
General settings
Operation: The operation of the auto recloser can be switched On or Off.
ExternalCtrl: This setting makes it possible to switch the auto recloser On or Off using an external
switch via IO or communication ports.
StartByCBOpen: The normal setting Off is used when the function is started by protection trip
signals. If set On the start of the auto recloser is controlled by an circuit breaker auxiliary contact.
LongStartInhib: Usually the protection trip command, used as an auto reclosing start signal, resets
quickly as the fault is cleared. A prolonged trip command may depend on a circuit breaker failing to
clear the fault. A protection trip signal present when the circuit breaker is reclosed will result in a new
trip. The user can set a maximum start pulse duration time tLongStartInh. This start pulse duration
time is controlled by the LongStartInhib setting. When the start pulse duration signal is longer than
set maximum start pulse duration, the auto reclosing sequence interrupts in the same way as for a
signal to the INHIBIT input.
tLongStartInh: The user can set a maximum start pulse duration time tLongStartInh. At a set time
somewhat longer than the auto reclosing dead time, this facility will not influence the auto reclosing.
A typical setting of tLongStartInh could be close to the auto reclosing dead time.
