5 SETTINGS
Three zones of phase distance protection are provided. Each 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 setting (common for the phase distance elements of all zones as entered under
SIGNAL SOURCE
!
GROUPED ELEMENTS SETTING GROUP 1(6)
2. The setting (common for the phase distance elements of all zones as entered under
MEMORY DURATION
!
GROUPED ELEMENTS SETTING GROUP 1(6)
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.
Ensure that the
PHASE VT SECONDARY VOLTAGE
menu) is set correctly to prevent improper operation of associated memory action.
