Protection Functions
The following application examples show the correct connection of
the voltage inputs. In the Figure 3.34 and Figure 3.35, the
applications require only one stage (Voltage measuring modes are
"1LL+U
/LLy " and "2LL/LLy "). Two stages are needed for the
0
application presented in Figure 3.36 (Voltage measuring mode is
"LL/LLy/LLz").
