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
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.
