Table 127: Momentary per phase direction value for monitored data view
Criterion for per phase direction information
The ANGLE_X is not in any of the defined sectors,
or the direction cannot be defined due too low
amplitude
The ANGLE_X is in the forward sector
The ANGLE_X is in the reverse sector
(The ANGLE_X is in both forward and reverse
sectors, that is, when the sectors are overlapping)
Table 128: Momentary phase combined direction value for monitored data view
Criterion for phase combined direction information
The direction information (DIR_X) for all phases is
unknown
The direction information (DIR_X) for at least one
phase is forward, none being in reverse
The direction information (DIR_X) for at least one
phase is reverse, none being in forward
The direction information (DIR_X) for some phase is
forward and for some phase is reverse
FAULT_DIR gives the detected direction of the fault during fault situations, that is, when
the PICKUP output is active.
Protection functions
The value for DIR_A/_B/_C
0 = unknown
1 = forward
2 = backward
3 = both
The value for DIRECTION
0 = unknown
1 = forward
2 = backward
3 = both
