Current Transformer Data for 1-phase Further Current Inputs
The number of 1-phase further current inputs depends on the device version. Such inputs are used for detec-
tion of the starpoint current of an earthed winding of a transformer, generator, or motor, shunt reactor, or
neutral reactor, or for different 1-phase measuring purposes. The assignment has already been carried out in
Section 2.1.4 Power System Data 1, margin heading “Assignment of Auxiliary 1-phase Measuring Locations”,
the assignment of the protection functions will be done in Section “Assignment of the Protection Functions to
the Measuring Locations/Sides”. These settings concern exclusively the current transformer data, regardless of
whether or not they belong to the main protected object.
