If parasitic currents (e.g. through induction) can be excluded when the circuit breaker
is open, these settings may normally be very sensitive. Otherwise the settings must
be increased correspondingly. In most cases the setting can be the same for all ad-
dresses displayed.
However, please note that current summation measuring errors may occur on the
sides which are fed by multiple measuring locations.
In the 1-phase busbar protection
, you can set such an open-pole current for each of
the up to 9 feeders (7UT613 and 7UT633 for 1-phase connection with or without sum-
mation CT) or 12 feeders (7UT635 with or without summation CT) of the busbar. The
maximum range of possible addresses includes:
Finally, it is also possible to monitor the residual currents at the auxiliary measuring
locations. These residual currents are needed by the dynamic cold-load pickup feature
of the earth overcurrent protection, if no side or measuring location is assigned to the
earth overcurrent protection. The maximum range of possible addresses includes:
Please remember to also allocate all binary inputs that are needed to generate a
manual close pulse for the various protection functions (FNos 30351 to 30360).
Note
In the following settings overview, the values are referred to the rated current of the
assigned side (I/I

).
