EMC Filters
II K A-6
Appendix A
Three-phase filters
EMC mains filters are necessary so as to
comply with EN 50 081 if a power converter
is to be operated at a public low-voltage
grid, in Europe, for example, with 400 V
between the phases. Grids of this kind
have an earthed neutral conductor. For
these cases, ABB offers its three-phase
mains filters for 500 V and 25 A ... 1000 A.
On local lines inside factories they do not
supply sensitive electronics. Therefore
converters do not need EMC filters.
In chapter
5.2 Installation in accordance
with EMC
the topic EMC filter is described.
