10.3.6.11 Initiation of reclosing from CB open information
If a user wants to apply initiation of auto-reclosing from CB open position instead of from
protection trip signals, the function offers such a possibility. This starting mode is selected by a
setting parameter
operations. Typically, one also set
contact of type NC (normally closed) to inputs 52a and RI. When the signal changes from CB closed
to CB open an auto-reclosing start pulse of limited length is generated and latched in the function,
subject to the usual checks. Then the reclosing sequence continues as usual. One needs to connect
signals from manual tripping and other functions, which shall prevent reclosing, to the input
INHIBIT.
