Module: Protection (Prot)
Direction Determination
The direction determination of the device is built in as part of the »Prot« module. This functionality is triggered as
soon as any of the overcurrent modules I[1] … [6] has been configured to work in directional mode (ANSI 67), and
the same is true of the directional mode of the measured and calculated ground fault protection (IG[1] … [4], ANSI
67N).
Measurement Values of the Direction Determination
Three directional values are permanently available under the menu path
[Operation / Measured Values / Direction detection]:
•
»Direction I« – Determined direction of the phase currents. (See also below, -->
Directional_Feature_PhaseOvercurrent.)
•
»Direction IG meas.« – Determined direction of the measured ground current. (See also below, -->
Directional_Feature_EarthOvercurrent_IX.)
•
»Direction IG calc.« – Determined direction of the calculated ground current. (See also below, -->
Directional_Feature_EarthOvercurrent_IR.)
These values offer the same information as can be seen in case of an alarm when checking the status flags under
[Operation / Status Display / Prot].
