Filter In A Grounded Line (Earthed Tn Or Tt Network); Three - Phase Filters; Single - Phase Filters For Field Supply - ABB DCS 600 Manual

Filter in a grounded line (earthed TN or TT
network)
The filters are suitable for grounded lines only, for
example in public European 400 V lines. Accord-
ing to EN 61800-3 filters are not needed in
insulated industrial lines with own supply trans-
formers. Furthermore they could cause safety
risks in such floating lines (IT networks).

Three - phase filters

EMC filters are necessary to fulfill EN 50081 if a
converter shall be run at a public low voltage line,
in Europe for example with 400 V between the
phases. Such lines have a grounded neutral
conductor. ABB offers suitable three - phase
filters for 400 V and 25 A....600 A and 500 V filters
for 440 V lines outside Europe.
Lines with 500 V to 1000 V are not public. They
are local lines inside factories, and they do not
supply sensitive electronics. Therefore convert-
ers do not need EMC filters if they shall run with
500 V and more.

Single - phase filters for field supply

Many field supply units are single - phase con-
verters for up to 50 A excitation current. They can
be supplied by two of the three input phases of
the armature supply converter. Then a field
supply unit does not need its own filter.
If the phase to neutral voltage shall be taken
(230 V in a 400 V line) then a separate filter is
necessary. ABB offers such filters for 250 V and
6...30 A.

The filters 25... 2500 A are available for 440 V and 500 V, and the filters
600...2500 A are available for 690 V too.
The filters can be optimized for the real motor currents:
I = 0.8 • I
; the factor 0.8 respects the current ripple.
