The positive- and negative-sequence current measured values of the virtual end,
formed by summation or subtraction of current values (primary and per unit
values), are also continuously determined and displayed as measured operating
data:
Positive-sequence current MAIN: Curr. Ineg,add p.u.
(005 149)
Negative-sequence current MAIN: Curr. Ipos,add p.u.
(005 150)
When the CB's contacts are open, it is also possible to force to zero the setting of
small positive- and negative-sequence current measured values if such
measured values are below additionally created settable thresholds.
