Provision of trigger signals to Recording functions
The 'TRIP COMMMAND1-A, -B, -C' and 'TRIP COMMMAND2-A, -B, -C' signals are viable to
operation of Recording function, which we shall see in Chapter
Provision for distance relay
The 'GEN.TRIP' signal is provided to direct the operation of the UVPWI relay in the distance
protection function, which we shall see in Chapter
CB trip signal production
(iii)
As illustrated in Figure 2.33-3, the 'TRIP COMMMAND1-A, -B, -C' and 'TRIP COMMMAND2-
A, -B, -C' signals are transferred to trip coils of the CB#1 and CB#2 when the signals "OPT-
TRIP-A, -B, and -C" or "OPT-TRIP" enter into the TRC function.
CB trip signals for 1CB system
When the TRC function operates in a single CB (1CB) system; the "TRIP COMMMAND1-A, -
B, -C" signals should be connected with BO circuits.

CBs trip signals for 1.5CB system
When the TRC function can operate in a single-and-a-half breaker system (1.5CB); the other
"TRIP COMMMAND2-A, -B, -C" signals also should be connected with other BO circuits. Table
2.33-8 summarizes the outputs signals of the TRC function in the 1.5CB system.

Sub-signal generation
(iv)
In a similar way to the Trip-signal collection, the Sub-signal generation groups the blocking
signals for ARC operation; it groups them into 'GEN.ARC-BLOCK' signal, as illustrated in
Figure 2.33-4. Blocking signal from the CBF function is also integrated into the 'GEN.ARC-
BLOCK' signal; then it is transferred to the ARC function.
