Address %$/$1&(9²/,0,7 determines the limit voltage (Phase-to-Phase),
above which the voltage symmetry monitor is effective (see also Figure 6-63). Address
%$/)$&7259 is the associated symmetry factor; that is, the slope of the
symmetry characteristic curve (Figure 6-63).
Address %$/$1&(,/,0,7 determines the limit current, above which the cur-
rent symmetry monitor is effective (see also Figure 6-62). Address %$/)$&
725, is the associated symmetry factor; that is, the slope of the symmetry charac-
teristic curve (Figure 6-62).
Address Σ,7+5(6+2/' determines the limit current, above which the current
sum monitor (see Figure 6-61) is activated (absolute portion, only relative to I
N
). The
relative portion (relative to the maximum conductor current) for activating the current
sum monitor (Figure 6-61) is set at address Σ,)$&725.
6.17.2.1 Settings for Measured Values Monitoring
In the list below, the setting ranges and default setting values for current-based set-
tings are for a device with a nominal current rating I
N
= 5 A. For a nominal current rat-
ing I
N
= 1 A, divide the Setting Options values and Default Setting values by 5. Con-
sider the current transformer ratios when setting the device with primary values.
Note:
Current sum monitoring is only in effect if the ground current for the line to be protect-
ed is connected.
