Description
This value contains the current measured at the current input labeled "IN". This
input is used for measurement of the earth fault current.
NOTE:
The ratio between the current measured at the input terminals and the displayed
current is adjusted by the setpoints EarthFltCurCTp and Im3/ErFlCurCTs.
