Figure. 5.3.4 - 91. When Idir> function has been set to "Non-directional" the function works basically just like a traditional non-
directional overcurrent protection function.
Read-only parameters
The relay's
Info page displays useful, real-time information on the state of the protection function. It is
accessed either through the relay's HMI display, or through the setting tool software when it is
connected to the relay and its Live Edit mode is active.

-360.00...360.00deg
0.01deg
The positive sequence current angle in relation to the positive sequence
voltage.
Expected
operating
time
0.000...1800.00s
0.005s
Displays the expected operating time when a fault occurs. When IDMT
mode is used, the expected operating time depends on the highest
measured phase current value. If the measured current changes during a
fault, the expected operating time changes accordingly.
Time
remaining
to trip
-1800.000...1800.00s 0.005s
When the function has detected a fault and counts down time towards a trip,
this displays how much time is left before tripping occurs.
