Because of the flexible setting options of the voltage measurand, the function itself does not determine the
current associated with the voltage. A suitable current-flow monitoring function must be created by the
user with the Continuous Function Chart (CFC), and connected to the binary input signal >Current
flow-criterion.
Operation as Supervision Function
If you want the tripping stage to have a reporting effect only, generation of the operate indication and fault
logging can be disabled via the Operate & flt.rec. blocked parameter.

SIPROTEC 5, Overcurrent Protection, Manual
C53000-G5040-C017-8, Edition 07.2017
Description
Because of the application, it makes sense that the stage is only active (that
is, not blocked) when a certain current flow is present (see note).
Current flow monitoring does not make sense for the application.
