Fig. 3-45: Measured operating data for the residual currents, shown here for end a
3.12.3.3 Positive- and negative-sequence currents
The positive- and negative-sequence current measured values of all ends
(primary and per unit values) are determined continuously and displayed as
measured operating data:

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.
