•
GND DIST Z1 Z0/Z1 MAG:
This setting specifies the ratio between the zero-sequence and positive-sequence imped-
ance required for zero-sequence compensation of the ground distance elements. This setting is available on a per-
zone basis, enabling precise settings for tapped, non-homogeneous, and series compensated lines.
•
GND DIST Z1 Z0/Z1 ANG:
This setting specifies the angle difference between the zero-sequence and positive-
sequence impedance required for zero-sequence compensation of the ground distance elements. The entered value is
the zero-sequence impedance angle minus the positive-sequence impedance angle. This setting is available on a per-
zone basis, enabling precise values for tapped, non-homologous, and series-compensated lines.
•
GND DIST Z1 ZOM/Z1 MAG:
The ground distance elements can be programmed to apply compensation for the zero-
sequence mutual coupling between parallel lines. If this compensation is required, the ground current from the parallel
line (3I_0) measured in the direction of the zone being compensated must be connected to the ground input CT of the
CT bank configured under the
DISTANCE SOURCE
. This setting specifies the ratio between the magnitudes of the mutual
zero-sequence impedance between the lines and the positive-sequence impedance of the protected line. It is impera-
tive to set this setting to zero if the compensation is not to be performed.
