†Note: A number of the operation identifiers are provided by the protection functions. For
example, the 'OC1-OPT-A' operation identifier is used to identify the pickup in the
first element of the overcurrent function (OC1) in phase-A. See respective
protection functions in Chapter
‡Note: 64 logical signals are selectable for recording. For example in this purpose, the
user may choose an operation signal on the circuits of the BIO modules (BIOs).
FL calculation result
(iv)
The location of the fault occurrence is recoded if the fault locator function (FL) operates.
Evolving faults
(v)
The fault recorder is able to record evolving faults† during the operation of the ARC function.
Strikes number for reclosing CB is also recorded.
†Note: The evolving faults are found during the 'ARC_IN_PROG' signal being generating.
For more information, see Chapter
Fault quantities and pre-fault-quantities
(vi)
Several quantity items (amplitude and phase angle of current, etc.) are memorized in the fault
recorder, as exemplified in Table 8.1-1 (for 'VCT12B' designed for 1CB†) and Table 8.1-2 (for
'VCT11B' designed for 1.5CB†). Quantities just before the fault are also memorized. The pre-
fault quantities are captured 10 seconds before tripping, but it is possible to take back longer
using the setting [Pre-Fault time].
