• PHS DIST Z1 REACH: This setting defines the zone reach for the forward and reverse applications. In the non-direc-
tional applications, this setting defines the forward reach of the zone. The reverse reach impedance in non-directional
applications is set independently. The reach impedance is entered in secondary ohms. The reach impedance angle is
entered as the
PHS DIST Z1 RCA
• PHS DIST Z1 RCA: This setting specifies the characteristic angle (similar to the 'maximum torque angle' in previous
technologies) of the phase distance characteristic for the forward and reverse applications. In the non-directional appli-
cations, this setting defines the angle of the forward reach impedance. The reverse reach impedance in the non-direc-
tional applications is set independently. The setting is an angle of reach impedance as shown in Mho Distance
Characteristic figures. This setting is independent from
tional supervising function.
• PHS DIST Z1 REV REACH: This setting defines the reverse reach of the zone set to non-directional (
setting). The value must be entered in secondary ohms. This setting does not apply when the zone direction is set to
"Forward" or "Reverse".
• PHS DIST Z1 REV REACH RCA: This setting defines the angle of the reverse reach impedance if the zone is set to
non-directional (
PHS DIST Z1 DIR
"Reverse".
• PHS DIST Z1 COMP LIMIT: This setting shapes the operating characteristic, producing the lens-type characteristic of
the mho function. The same limit angle applies to both the mho and supervising reactance comparators. This setting
improves loadability of the protected line.
• PHS DIST Z1 DIR RCA: This setting selects the characteristic angle (or 'maximum torque angle') of the directional
supervising function. The directional function is an extra supervising function as the dynamic mho characteristic itself is
a directional one. The directional function uses the memory voltage for polarization. This setting typically equals the
distance characteristic angle
• PHS DIST Z1 DIR COMP LIMIT: Selects the comparator limit angle for the directional supervising function.
