'FC*_OPT_TRIP' represents a three-pole trip command. 'ARC-BLOCK' represents

a signal used to block the operation of the ARC function; the 'ARC-BLOCK' signal

is transferred to the autoreclose function (ARC). Incidentally, the term 'FC*'

represents one of the relay elements connected to the TRC function.

Table 2.23-2 illustrates CBF function can generate a re-trip signal and an ARC-BLOCK signal.

Protection function

Note: 'X' represents a Valid signal for the TRC'. 'CBF_ARC-BLOCK' signal is grouped

with the 'FC*_OPT_ARC-BLOCK' signal in the Sub-signal generation scheme.

Recording identifiers for respective fault types

Table 2.23-3 shows an identifier signal for the recording function generated when a fault is

detected by the protection functions. That is, the identifier is generated in each protection

function (relay element) and is transferred to the recording function.
