IN Measured
The function operates with the measured ground current IN. This is the
recommended setting unless there is a specific reason to use the calculated
zero-sequence current 3I0.
3I0 Calculated
The function operates with the calculated zero sequence current 3I0. This
setting option can be used when applying a redundant 50N/51N function for
safety reasons.
