3.17.2.3 Functionality
The residual current preprocessing function RESTCTR is used for setting up the
residual current measurement channels. Input channels for RESTCTR are either
physical hardware or IEC 61850-9-2 sampled value channels. The output IRES_MEAS
channel of RESTCTR can be connected to different applications which require
measured residual current.
The current transducer selection can be made by setting
Current input type
to
"Current trafo" for conventional CT or to "Current sensor" for current sensor type.
The residual CTs' primary rated current can be set using
Primary current
setting.
The setting
Secondary current
defines the nominal current of the CT's secondary
winding. This is used as a reference to scale measurements accordingly.
