5-216 L60 LINE PHASE COMPARISON SYSTEM – INSTRUCTION MANUALGROUPED ELEMENTS CHAPTER 5: SETTINGS5PHS DIST Z1 DIR — All phase distance zones are reversible. The forward direction is defined by the PHS DIST Z1 RCA setting,whereas the reverse direction is shifted 180° from that angle. The non-directional zone spans between the forward reachimpedance defined by the PHS DIST Z1 REACH and PHS DIST Z1 RCA settings, and the reverse reach impedance defined byPHS DIST Z1 REV REACH and PHS DIST Z1 REV REACH RCA as illustrated in the following figures.PHS DIST Z1 SHAPE — This setting selects the shape of the phase distance function between the mho and quadrilateralcharacteristics. The selection is available on a per-zone basis. The two characteristics and their possible variations areshown in the following figures.Figure 5-109: Directional mho phase distance characteristicFigure 5-110: Non-directional mho phase distance characteristic
