GROUPED ELEMENTS CHAPTER 5: SETTINGS
— All phase distance zones are reversible. The forward direction is defined by the setting,
PHS DIST Z1 DIR PHS DIST Z1 RCA
whereas the reverse direction is shifted 180° from that angle. The non-directional zone spans between the forward reach
impedance defined by the and settings, and the reverse reach impedance defined by
PHS DIST Z1 REACH PHS DIST Z1 RCA
and as illustrated in the following figures.
PHS DIST Z1 REV REACH PHS DIST Z1 REV REACH RCA
— This setting selects the shape of the phase distance function between the mho and quadrilateral
PHS DIST Z1 SHAPE
characteristics. The selection is available on a per-zone basis. The two characteristics and their possible variations are
shown in the following figures.
