The effective operating quantities of the sensitive directional power elements are
displayed here. The display may be useful to calibrate the feature by compensating the
angular errors of the CTs and VTs with the use of the RCA and CALIBRATION settings.
Directional Power 1 (Directional Power 1)
Range: -214748364.8 kW to 214748364.7 kW
Default: 0.0 kW
Directional Power 2 (Directional Power 2)
Range: -214748364.8 kW to 214748364.7 kW
Default: 0.0 kW
Directional Power X (Directional Power X)
Range: -214748364.8 kW to 214748364.7 kW
Default: 0.0 kW
Path: Metering > Wattmetric Ground Fault
The menu displays the wattmetric ground fault element operating power value.

Wattmetric Ground Fault [X] (Wattmetric Ground Fault X)
Range: -21474836.48 W to 21474836.47 W
Default: 0.00 W
Path: Metering > CT Supervision 1(X)
CTS SYM Imin
Range: 0.000 to 120000.000 A in steps of 0.001
Default: 0.000 A
This value is the minimum phase current magnitude of the three phases for the
symmetry check in the CT Supervision monitoring element.
CTS SYM Imax
Range: 0.000 to 120000.000 A in steps of 0.001
Default: 0.000 A
This value is the maximum phase current magnitude of the three phases for the
symmetry check in the CT Supervision monitoring element.
