Operational Measured Values
The operational measured values are not preconfigured in the Voltage-current 1-phase function group. You
can instantiate them in the function group or delete them from the function group. You can find the opera-
tional measured values in the DIGSI library, in the folder FG Voltage-current 1-phase under Measurements
→ Operational values.

You can find the parameters Rated operating current, Rated operating voltage, and Rated
apparent power in the General function block of the Voltage-current 1-phase function group. You can
find the parameter Rated frequency in the General function block of the Device settings.
NOTE
The frequency can be calculated from the voltage or current measured value.
The active and reactive power are only displayed if the voltage and the 1-phase current are connected to
the function group. If the connected voltage is a phase-to-ground voltage (VA, VB, VC) or any voltage Vx,
the specific power values are displayed. Otherwise the power is displayed as not available.
Application and Setting Notes
NOTE
Prior to creation of the protection functions in the function group, these functions should first be
connected to the appropriateCircuit-breaker function group.
