3.23.7 General Starting
A general starting is triggered if the current in one phase exceeds the 1.05-fold
of the set reference current value. It can be selected whether the starting of the
negativesequence and residual current stages should be taken into account in
the general starting decision. The general starting triggers a timer stage. A signal
is issued when the time period of this stage has elapsed.
