Table 64:
Phase combined fault direction value
Criterion for combined fault direction information
Value for fault direction FAULT_DIR
The fault direction information for all phases is
unknown
0 = unknown
The fault direction information for at least one
phase is forward, no phase in reverse
1 = forward
The fault direction information for at least one
phase is reverse, no phase in forward
2 = backward
The fault direction information for some phase is
forward and for some phase is reverse
3 = both
Cross-polarizing as polarizing quantity
When cross polarizing is used as a polarizing method, the directional information is
calculated with formulas defined in
