The phase mho distance function uses a dynamic 100% memory-polarized mho characteristic with additional reactance,
directional, and overcurrent supervising characteristics. When set to "Non-directional", the mho function becomes an offset
mho with the reverse reach controlled independently from the forward reach, and all the directional characteristics
removed.
The phase quadrilateral distance function is comprised of a reactance characteristic, right and left blinders, and 100%
memory-polarized directional and current supervising characteristics. When set to "Non-directional", the quadrilateral func-
tion applies a reactance line in the reverse direction instead of the directional comparators. Refer to Chapter 8 for additional
information.
Each phase distance zone is configured individually through its own setting menu. All of the settings can be independently
modified for each of the zones except:

The common distance settings described earlier must be properly chosen for correct operation of the phase distance ele-
ments. Additional details may be found in chapter 8: Theory of operation.
