t-dead
While in the dead timing state »
t-dead«, the pre-set dead timer for current AR shot is timing and cannot be interrupted
unless there are any blocking or lockout conditions coming.
After dead timer elapses, the autoreclosure issues the breaker reclosing command and goes into the next state:
»R
ECLOSING
«, only if the following conditions are met:
The breaker is in open position;
The breaker is ready for next reclosing operation (if the CB Ready logic input is used);
No pickup from current (assigned) AR initiate function(s);
No trip from current (assigned) AR initiate function(s); and
No general tipping command.
Before issuing the breaker reclosing command, the current shot counter will be incremented. This is very important for
the shot-controlled initiate and blocking functions. Before entering into the »R
ECLOSING
« state, the pre-set breaker
reclosing supervision timer (»
t-Brk-ON-cmd«) will also be started.
