The standards, IEC 61000-3-2, -3, -11 and -12 are under revision (-11
later), so if you can get your existing instrument repaired, it will
serve for a few years until the new standards are published and updated
instruments are available. I should say that no huge technical changes
are being made, but often the devil is in the detail. Quite a lot of
revision of texts is involved, intended to add clarity. IEC 61000-3-10
on emissions in the range 2 kHz to 9 kHz is also progressing and will
be published perhaps in 2028. A comprehensive test instrument might also
allow those measurements.

Hello everyone.
Our 25 year old Test Equipment for performing the Harmonic and Flicker
Emissions and Dips tests (4-11) decided to die today. I put in a
request for repair but things have changed so much of the last 25-30
years, maybe it would be money better spent to buy something new.
Any recommendations? (please reply off-line so not to violate any rules)
Any warnings on what to avoid?
For a system that will do up to 230V 16 amps per phase, what kind of
money can I expect to pay?
There are so many new players out there I am not sure who offers what,
and I need to get the lab back up and running soon.
Thanks to all for any advice or recommendations.
