Current Thresholds Definitions:
The following values have current threshold settings; each value has three different set points with
different delays.
Instantaneous phase (50P-1,2,3)
Instantaneous negative sequence (50Q-1,2,3)
Instantaneous ground (50G-1,2,3)
For each point, there are three settings as shown in the following for 50P-1.
Enable instantaneous phase (50P-1)
If this is enabled, the corresponding status indication and logic bit will be driven when the measured
value exceeds the pickup value for the required time delay.
50P-1 Pick Up
This setting determines the threshold point
50P-1 Time Delay
This sets a minimum delay, during which the measured value must exceed the threshold before the
indications are set.
Once all the settings have been entered click save.
