Quad characteristic
Figure 2.1-13(a) and (b) show the Z*S and the Z*G used in the Quad characteristics. For
example, the reach of Z*S (top line) is defined by reactance X and the reach value should be
set for the scheme switch [Z*S-X.Reach]. A resistive element (left line) and a directional
element (bottom line) can be set by the settings [Z*S-DX.Angle] and [Z*S-DR.Angle]
respectively. The resistive elements (right and left lines) can be configured by the settings [Z*S-
R.Reach] and [Z*S-R.Angle]; the blinder (left line) is used to cut the area of the Quad
characteristic by applying settings [Z*S-R.Reach] and [Z*S-R.Angle].
The 'knee' function is configured by the settings [ZSF-X.GrAngle1] and [ZSF-X.GrAngle2].
When On-Adapt is set for the scheme switch [ZS-X.GrAngleEN], the 'knee' function operates
when power flow is detected, similar to the MHO element.
