Hi all
Thanks for the replies,
The filter is a ETS Lindgren Filter N6003 installed on the EMC Chamber wall.
The filter is defined as a 4 line 230/400V 32A <450Hz filter.
When used for DEF STAN EMC measurements and loaded by the 4 of 10uF prior to
the 5uH LISNs it appears to be OK,
however when
Hello David,
I believe this document explains it:

Another possibility is adjusting power factor to account for the filter
effect. This is a common effect and a chamber outfitted with such filters
often has remotely-controlled power factor correction. A long time ago,
when chamber EMI filters cut in at 150 kHz instead of 10 kHz, the impact
wasn¹t
The filter is probably designed for 50Hz or 60 Hz mains. It probably
isn't saturating at a higher input frequency, but your voltage
measurements indicate that it may be resonating. I think you need a
filter specifically designed for 400 Hz mains.

Hi members
Can anyone offer some advice.
Have issues with EMC Chamber RF Filter 3 phase.
Using 115V 400Hz single phase supply from a static convertor, filter looks like
it is saturating.
Ambient levels failing between 6kHz to 150kHz.
Voltage of phase at static convertor 115.8Vrms but at EUT on be

I'm not speaking from experience, as I don't work with this standard, but the
free preview shows that A1 replaces A11 and has a summary of the history of

Hello David,
amendment A1:2020 is the adoption of CISPR 32:2015/A1:2019 by CENELEC (without
any modification), while amendment A11:2020 adds the European Foreword and
Annex ZZ "Relationship between this European standard and the essential
requirements of Directive 2014/30/EU [2014 OJ L96] aimed
Hello
I have seen EN 55032-2015 listed with either A1-2020 or A11-2020.
Is there any difference between them or is it just a typo?
