Measurands
Within the protection stage, the compensated and the non-compensated unbalanced currents are available.
Use parameter Measured value to select one of the 2 values. Both values are displayed as measured values
of the function at the function stage.
Pickup, Operate Delay
If the selected measurand exceeds the threshold, the stage picks up. The pickup starts the operate delay, and a
fault-location information is issued. More information can be found in this chapter under Fault-Location Infor-
mation, Page 1013. If the threshold is exceeded during the entire operate delay, the operate indication is
issued.
