(i)-1-2 Mho with reactance characteristic

Figure 2.1-12 (a) and (b) show Z1S MHO element and Z1G MHO element set with

reactance X.

The ZS with the MHO reactance characteristic should be set using the setting [Z*S-

X.Reach], when the user set On for the scheme switch [Z*S-MhoX.EN]. Similarly, ZG

should be set using the setting [Z*G-X.Reach], when On set for the [Z*G-MhoX.EN].

The 'knee' function is configured by using 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.

For the Mho characteristic, a composition component (Z-X) is provided. As shown in

Figure 2.1-12 (a), if Z1S is set with reactance components (X), other components can

be set using impedance components (Z).

A directional reactance element 'DX' (left line crossing the originate) can be set by the

settings [Z*S-DX.Angle] when On set for the [Z*S-MhoDX.EN]. Similarly, ZG should

be set using the setting [Z*G-DX.Angle] when On set for the [Z*G-MhoDX.EN].
