TRC function. ‘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 2.26-3 and Table 2.26-4 summarize the operation results in the TRC function. Table
2.26-3, shows the correspondents between the input signals (which are signals provided from
the protection functions) and their reasons (that is, types of faults). For example, if a fault
(1LG in phase A) occurs, ‘FC*_OPT_TRIP-A’ signal may be provided for the TRC function from
a protection function; the TRC function may generates ‘TRIP-COMMAN1-A’ and ‘TRIP-
COMMAND2-A’ signals when the scheme switch [
TP-MODE
]=
PER-PHASE
(see Table 2.26-4).
Note that Table 2.26-3 illustrates generic operation rules concernin g fault types; the inputs
depend on the practical operation of relay functions. Hence, the user should figure out actual
inputs using Table 2.26-2 together with the characteristics of respective protection functions.
Note the TRC outputs will be influenced by the signals generated in the ARC function.
That is, when a CB1_BRIDGE or a CB1_94TT signal is generated and it is injected into the
TRC function, the TRC function is instructed to output a three-phase tripping (i.e., issuing
CB1_94TT following ARC1 FT or TPAR) or the TRC function is instructed to operate
unconditionally in three-phase tripping mode (i.e., issuing CB1_BRIDGE following ARC1
UNREADT). We shall see a number of operation settings [
ARC1-MODE
] and [
ARC2-MODE
] in
the ARC function.
