NOTE
With the parameter 613 Gnd O/Cprot. w. in the Power System Data 1 (see 2.1.3.2 Setting Notes), you
can identify whether the neutral currents IN in sectionalizer use the measured values Ignd (measured)
or the values 3I0 (calcul.) calculated from the 3-phase currents.
The timer symbol of parameter 9528 means: when the rising edge comes, timer starts. The timer restarts
when the next rising edge comes.
Setting Notes
General
The sectionalizer protection is only in effect and accessible if address 376 Sectionalizer is set to With
prot. or Without prot..
If you select the option Without prot., the functions marked with No in the following table, are switched
off completely and these protections in all setting groups are hidden, although these protections are set to be
enabled in device configuration.
If you select the option With prot., the protections in all setting groups work normally.
If the sectionalizer function is not required, then Disabled is set.
The following table shows the functions influenced by the sectionalizer. The functions marked with No are
protection- related functions, which are switched off completely when Without prot. is chosen.
