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:
1.
The
SIGNAL SOURCE
setting (common for the distance elements of all zones as entered under

2.
The

setting (common for the distance elements of all zones as entered under

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
.
Although all zones can be used as either instantaneous elements (pickup [
PKP
] and dropout [
DPO
] FlexLogic™ operands)
or time-delayed elements (operate [
OP
] FlexLogic™ operands), only zone 1 is intended for the instantaneous under-reach-
ing tripping mode.
Ensure that the
PHASE VT SECONDARY VOLTAGE
setting (see the
SETTINGS
ÖØ
SYSTEM SETUP
Ö
AC INPUTS
ÖØ
VOLTAGE BANK
menu) is set correctly to prevent improper operation of associated memory action.

PHS 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 for-
ward reach impedance defined by the
PHS DIST Z1 REACH
and
PHS DIST Z1 RCA
settings, and the reverse reach imped-
ance defined by
PHS DIST Z1 REV REACH
and
PHS DIST Z1 REV REACH RCA
as illustrated below.
