Figure 141: Configurable operating sectors in phase angle characteristic
Table 294: Momentary operating direction
Fault direction
The value for DIRECTION
Angle between the polarizing and operating
quantity is not in any of the defined sectors.
0 = unknown
Angle between the polarizing and operating
quantity is in the forward sector.
1= forward
Angle between the polarizing and operating
quantity is in the reverse sector.
2 = backward
Angle between the polarizing and operating
quantity is in both the forward and the reverse
sectors, that is, the sectors are overlapping.
3 = both
If the Allow Non Dir setting is "False", the directional operation (forward, reverse)
is not allowed when the measured polarizing or operating quantities are invalid,
that is, their magnitude is below the set minimum values. The minimum values can
be defined with the settings Min operate current and Min operate voltage. In case
of low magnitudes, the FAULT_DIR and DIRECTION outputs are set to 0 =
unknown, except when the Allow non dir setting is "True". In that case, the
