ID201] to [OP Mode ID264] are used for general purposes to record the logical signals.
†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)
Numbers of metering power amplitudes, phase angles, ratios, etc. are memorized in the fault
recording function. Table 8.1-1 shows memorized quantities, of which types are dependent on
the order, which the user can identify it with the ordering number at Positon "S, G, and T".
When a fault occurs, the function memorizes the fault information by which the function
cannot observe the fault (i.e., fault duration time); but, it can memorize the information just
before the fault has occurred (i.e., pre-fault quantities). The user can adjust the function start
with setting [Pre-Fault time].
