Figure 149:
Configurable operating sectors in phase angle characteristic
Table 325:
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 function is allowed
