Section 12
Control
tSlaveDeadTime : When activating the WAIT input, in the auto recloser set as slave, every dead
timer is changed to the value of setting
operation. When the
breaker, the slave is released to continue the auto reclosing sequence after the set
tSlaveDeadTime . The reason for shortening the time, for the normal dead timers with the value
tSlaveDeadTime , is to give the slave permission to react almost immediately when the WAIT
of
input resets. The minimum settable time for
and slave should not send the circuit breaker closing command at the same time.
12.3 Apparatus control
12.3.1 Application
The apparatus control is a functionality for control and supervising of circuit breakers,
disconnectors, and earthing switches within a bay. Permission to operate is given after
evaluation of conditions from other functions such as interlocking, synchrocheck, operator
place selection and external or internal blockings.
