Re: [PSES] IEC 61000-6-5 vs. IEC 61000-6-2

There are also minor differences if the product is installed in a gas-insulated 
substation, air-insulated substation, or a power station within 61000-6-5.

There is a fair amount of EMC standards that might be applicable to a device 
within a substation depending on the location of installation and function. If 
the product has a protection function, then the 60255-1, 26 might be applicable 
while protection communications might need 61850-3.

There are a number of differences including:

  *   Zoning of different areas which then require different levels of tests 
against 61000-4-4; 61000-4-16 and 61000-4-18
  *   61000-4-8 Mag Field is 100 A/m continuous and 1000 A/m for 1 s (but only

Re: [PSES] Immunity test field strength, residential setting

2023-07-27 Thread Bill Morse
Hello All,

I am wondering if the 20 V/m level was borrowed from IEEE C37.90.2, which is 
referenced in UL CCN NRGU for Protective Relays. The IEEE C37.90.x series is 
one of the industry standards for items associated with protecting and control 
of the electrical grid. It does not seem quite right but is the only link that 
seems somewhat associated.

Without being on the working group I can only speculate on reasoning, but I can 
imagine a conversation that went something like this:

Person A - "Considering the power tools, welders, spark plugs, metal lathe, end 
mill, wireless phones, short-range two-way radios, and other electrical noise 
generators I have had and used in my garage maybe the radiated immunity levels 
should be higher than 3 V/m for this end use environment."

Person B - "Your right, I remember the time "

Hi Brian,

20V/m is seen in some bands for rail standards, but I've seen it elsewhere, 
usually where there is a functional safety aspect.

Attached table from EN 55035 shows estimates of field strength vs distance from 
typical transmitters. There is also something in EN 60601-1-2 (clause 8.10 from

Subject: [PSES] Immunity test field strength, residential setting

 Hello colleagues,

We are building EV Chargers for residential markets (not just US) and one of 
the safety applicable standards is UL 2231-2.  It calls out  IEC 61000-4-3 for 
immunity testing parameters, which states a requirement for a field strength of 
20V/m.  Our EMC expert says typically testing is "done at 3 Vrms, which is 
standard for most products in residential environments."   He can only test up 
to 10V, and we're hearing the same from an overseas lab to whom our 
manufacturer refers.

Does FCC Part B have guidelines for field strength we can cite?   Can some 
offer this "DC guy" (aka, 60 Hz) a quick definition of what the 20V/m 
represents?

I'm guessing 20 V/m is for higher density commercial applications, aka charging 
stations, so we probably need an exception for residential.

Thank you!

RE: Sensitivity of PCS phones

2003-04-22 Thread Bill Morse

RSSI for some network certifications very it might be  -104dBm for one network
while others it can be -98dBm. Some radios will go down to -107dBm. The
numbers are measured at the antenna jack of the radio; so antenna gain and
other physical parameters effect the overall RSSI.

Someone correct me if I am wrong here, the GSM network certifications
governing documents are PTCRB and GCF, these documents list what test need to
be preformed and reference the governing GSM document on what the pass/fail
criteria and how to do the test. In this case it's GSM 11.10 section II.4.2.

If you are on a CDMA network the RSSI is the same.

The original model is no longer available.  Unfortunately, I can't seem to

information on the sensitivity of the various brands of phones offered by
Sprint.  Do any of you know where this type of information can be found?

The example was included to engage the reader from the start; demonstrate

 In 1967 off the coast of Vietnam, a jet landing on the aircraft carrier 
 U.S.S. Forrestal was briefly illuminated by carrier-based radar. This is 
 quite a normal event, however the energy from the radar caused a stray 
 electrical signal to be sent to the jet weapon systems. The result was an 
 uncommanded release of munitions that struck a fully armed and fuelled 
 fighter on deck. The subsequent explosions killed 134 sailors and caused 
 severe damage to the carrier and aircraft. 
 
 This is an appallingly bad example, insofar as it was caused by a 
 **fault condition**. EMC standards, and the testing itself, do not take 
 fault conditions into account. There is a separate subject 'EMC and 
 functional safety', which is incredibly complicated. If you just think 
 about it for a while, you will see why. 
 
 Don't let your audience think that EMI occurs only when source or victim 
 is faulty. EMI occurs when both would be working perfectly normally if 
 the EMI were not present.

Power pack placement during emissions testing.

2002-12-05 Thread Bill Morse

I am in a discussion and would like to see what the general opinion is. 

The discuss centers around where to place an external power supply while doing 
CISPR 22 emissions testing; on the table, on an insulator in close proximity 
with the ground plane or on the ground plane.

The power supply is auto ranging with an input from 100VAC-250VAC with a dc 
output, power is feed into power supply from a standard IEC 60320 cord set. The 
output is non-shielded 2-conductor cable with a barrel connector at the end. 
The output cable length is about a meter.

The following are from CISPR 22
Section 8.1 the EUT shall be configured, installed and arranged and operated 
in a manner consistent with typical applications.
Section 8.1.1 to paraphrase, find the configuration for the highest emissions.
Section 8.1.2 The EUT situation relative to ground plane shall be equivalent 
to that occurring in use,.
Section 9.3 Floor-standing EUTs shall be placed on a horizontal metal ground 
plane,...,but not in metallic contact with the ground plane.
Section 9.4 Equipment designed for both table-top and floor-standing operation 
shall be tested only in the table-top configuration,.
Section 10.4 Floor-standing EUTs shall be placed directly on the horizontal 
metal ground plane, the point(s) of contact being consistent with normal use, 
but separated from the metallic contact with the ground plane by up to 12mm of 
insulation..
Figure 12  Test configuration: floor-standing and table-top equipment 
(radiated measurement) Note 4) EUT and cable shall be insulated from the 
horizontal metal ground plane.

When the power supply is on the table its emissions are 6dB below the class B 
limit, on a 2mm insulator on the ground plane it is 2dB below class B limit, 
and when placed on the ground plane it is over the class B limit by 1dB.

Reading the rules above it seems I can justify placing the power supply in all 
three locations.

My justification for placing it on the ground plane is that this configuration 
predominates in the typical end user setup and I must follow the worst case 
emission configuration.

But considering what seem to be conflicting sections in CISPR 22 I would like 
to see what the general opinions and comments are.

Appreciate the responses and help

The technique of temperature variation is that

Just tapping on the pcb will also be audible, not
to let alone the effect of a freezing spray !
But you definitely need a BFO equipped (measuring) receiver.
A spectrum analyser is of no use here (grin).
This really is the fastest way of finding out the real
source of a interfering spectral line.

Note also that the difference between data/adress lines
and R/W CE and Clcok emissions can easily be distinguished
by the notable AM modulation (rythme) and using the speaker of
your receiver it's easy to distinguish between
foreign sources, (radio tv amateur cellular) and even other
equipments (PC) in the neighbourhood.
I even can distinguish between multiple processors on a large system.
If your supply is not well stabilized, you will even hear the
100 (120) Hz hum on your spectral lines !

This technique in combination with
your own ears is truly sensitive in a quality point
of view: I have proposed in the past to use a measuring receiver
for debugging purposes: a mal functioning microprocessor
will definitely produce another sound then it's fully
functioning brothers/sisters. You may astonish your
collegues by fault debugging through walls !!! ;))

Automated measuring systems are of no use outside
the shielded room for exactly the lack of distinction
between spectral lines, and those who work with
a spectrum analyser do not know what they are missing...

RE: Emissions quick test

2002-08-21 Thread Bill Morse

Every person working in the EMC field has their own techniques when dealing will
emissions issues. Mostly based on past experiences, product type, what tools
they have handy or can afford plus the political atmosphere where they work.

I am no exception, part of my list of tools include:

EMCO 3142B antenna
Fischer Custom Communications current clamp F-130B frequency range 100kHz -
1GHz.
EMCO 7405 Probe set
And a CASSPER ETS Model 2000 Virtual Chamber
Lots of small hand built probes

For me the political atmosphere is time to market and then the cost of the fix,
so any tool that speeds up troubleshooting and gives more options is easy to
justify.

The CASSPER system is mostly billed as an ambient cancellation system, which it
does fairly well up to 30dB for external outside the building noise. For
internal noise in the room/building that you are using it in it has no effect. I
vary seldom use this part of the system.

Personally I think they are not advertising correctly. 

The source localization capabilities of the unit are amazing. For reasons
unknown the design engineers where I work with like using 4MHz, 12MHz and 24MHz
clocks to run the different processors in our systems; talk about stack-up. I
think they're punishing me for transgressions in a past life. Our typical test
methodology for testing the EUT is to take it to our favorite 10m chamber if it
fails, it does happen once and awhile, we take it back to our lab and
troubleshoot it. 

I can go from looking at the signal with the CASSPER with the 3142B antenna on
channel 1 and current clamp on channel 2 using the source localization mode and
find the radiating element, typically a cable. Then switching the current
clamp, now clamped on the radiating element to channel 1 and a near field probe
on channel 2 I can find the trace and driver circuit which is the source of the
emissions. Total time under 10 minutes usually. Solutions about what to do about
it sometimes take a bit longer, but now I know the driver, path and radiating
element. I can now choose how to attack the issue to bring product into
compliance; driver, path or radiating element.

I once built a test bed with dithering clocks operating at 24MHz then mixed them
together with one of the clock signals having a 10dB attenuator in line with it.
The system used an inductively coupled loop antenna to guarantee that it would
radiate. Even with the same percentage of dithering I could tell the dithering
clocks apart.

Like any other tool it has its quirks and limitations that have to be learned
but it does the job. It is not however inexpensive.

Hi all,

Does anyone know of a  down- and- dirty , inexpensive method or equipment
for sniffing out emissions issues?  I've used a Spectrum Analyzer in the
past with a series of different probes, but that tends to be costly.  Also,
Is there a universal probe kit out there?

Thank you in advance.

RE: Need copies of specs addressing ISM bands in Europe

2002-08-12 Thread Bill Morse

On the left side of web page is bookmark for Frequency Plans then go to European
Allocations ECA on that page these are the purposed for frequencies to be
harmonized within the EU, on the right of the original page are the individual
country allocation links. 

The best you can hope for is that frequency allocation chart directs you to the
correct standard for that band and use. The technical information will be in the
standard. If it is an ETSI doc you can download them for free at
http://pda.etsi.org/pda/queryform.asp.

ETSI EN 301 489-1 might help.


Questions to ask:

Does the product fall under the RTTE?
Does the product fall under a harmonized frequency allocation?
Is there a harmonized standard?
Is it Class 1 or Class 2 product under the RTTE?
If its Class 2 then you will be needing the individual country link and doing
individual country certifications/notifications.

For the quick response, hope this helps

Bill, Rich,

Just couldn't find out all of what I wanted there.  Did find individual
country's allocation for ISM bands and that was encouraging.  What am I
doing wrong?


At this site I at least found some numbers:

http://europa.eu.int/comm/enterprise/newapproach/standardization/harmstds/re
flist/radiotte.html

  ETSI EN 300 328-2 V1.1.1 (07-2000) Electromagnetic compatibility and Radio

equipment operating in the 2,4 GHz ISM band and using spread spectrum

But no documents.


My question is still, What is the equivalent European requirement that
matches FCC Part 15.247 regarding ISM bands?

RE: Australian TS001 now part of AUS/NZ60950?

2002-05-17 Thread Bill Morse

The Australian ACA TS 001 Safety Requirements for Customer Equipment states that
customer equipment shall comply with AS/NZS 3260
From TS 001

AS/NZS 3260 [4] is closely aligned with IEC 950 [6] and has variations to suit
Australian conditions

You should verify that the test house is testing to the deviations and list TS
001 as a reference in the report.


You also have to comply with TS 008 Requirements for Authorized Cabling Products
for the Telco Cable if you are shipping with one.
TS 008 in turn calls out a document named Telecommunications Labeling (Customer
Equipment and Customer Cabling) that cables also must meet.

Most citizens of most countries enjoy the security that comes from having
thrashed out land rights, territorial disputes, and the systems of law and

America is one of the few places in the West that relies on firearms as a

This is poor judgement. 
Firearms are offensive weapons not negotiating tools. 
Giving someone a gun escalates an already dangerous situation. 
Now you want the pilot to not only assure the safety of the plane but also
be an effective executioner. 
Asking too much IMHO.
Unfortunately America was taken by force and is defended by force and is
