I made some measurements once in a 3 meter anechoic chamber built for
EN61000-4-3. I was interested in the disturbance a wire causes in a field
due to picking up the field, the resultant currents flowing in such a way as
to cancel the field that caused them, etc. In order to assess the effect,
I read in !emc-pstc that Paolo Peruzzi paolo.peru...@esaote.com wrote

Mike, are you aware of the major changes to the 2nd revision of IEC
61000-4-11?

Remember the Hairdryer saga and 55014. Well a report has now been issued which
was prepared by Richard Marshall on behalf of Radiocommunications agency in
the UK. It makes for very interesting reading.
Radiocommunications Agency has announced a Study into how CISPR14 Part 1

There is a new document in the works, IEC 61000-4-34, for dip interrupt
testing of products drawing greater than 16A. It is currently a CD
(Committee Draft). TC77A WG6, who is responsible for this document, meets in
Spain in September, after which a CDV (Committee Draft for Vote) is
possible. It
Paolo,
I am not aware of a commercial or EN standard for more than 16 amperes.
There are some military standards that also address this. The one that I
have seen in the past was MIL-STD-704.
From a product specification perspective, the customer or company can create
a standard calling many
Hi all,
Is there any basic standard concerning voltage dips and short interruptions
immunity for equipment with input current larger than 16 amps per phase?
And more: can a product standard prescribe such test for equipment with
more than 16 amps per phase and still refer to 61000-4-11 as
Joe,
certainly not a big help, the following is the English version of MPHPT's
press release. It says it's a consultation paper - unfortunately it just
refers back to the Japanese document.

Has anyone investigated the difference in performance of different chamber
sizes when performing the radiated immunity (-3) test at low frequencies
(e.g.,
between 80 MHz and 100-150 MHz)? The field uniformity is calibrated in
E-field,
but I would expect the total EM field (E and H components)
9 matches
