Signal '1' is generated when there is no contradiction between the
various signals, that is only one signal is picking up.
CB1 F.BRIDGE
800001EBB8
READY
When FT is selected, the ARC function send 'CB1_BRIDGE' signal for the TRC function
to be the CB being tripped in three-phases, regardless of the condition of the tripped phase,
the operation of respective protection elements, and the ARC settings; the ARC function does
not operate (i.e., ARC1-FT).
When TPAR is selected, the TRC and the ARC functions operate by the rule that the CB
is tripped in three-phases and can be reclosed. That is, 'CB1_BRIDGE' signal is sent for the
TRC function so that the CB will be tripped in three-phases forcibly even if a GEN.TRIP-A
(TRIP COMMAND-A) signal is only generated in the TRC function (as well as GEN.TRIP-B
and GEN.TRIP-C). Note the CB will be tripped in three-phases forcibly, even if a single-phase
fault is detected and instructed a single-phase tripping by the relay applications.
