Three - phase filters
EMC filters are necessary to fulfil the standard for
emitted interference 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.

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. According to
EN 61800-3 filters are not needed in insulated indus-
trial lines with own supply transformers. Furthermore
they could cause safety risks in such floating lines (IT
networks).
Single - phase filters for field supply
Many field supply units are single - phase converters 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 can be optimized for the real motor currents:
I
Filter
= 0.8 • I
MOT max
; the factor 0.8 respects the current
ripple.
Lines with 500 V to 1000 V are not public. They are
local lines inside factories, and they do not supply
sensitive electronics. Therefore converters do not need
EMC filters if they shall run with 500 V and more.
