Hi Ken,
This probably won't help a lot, but the small company was a father and sons
company. The father was Tony Ciarcio or something close to that. I'm totally
blanking on the company name. Maybe another list member has better memory
than I!

I’m interested in all forms of research into the additive affect of a ground
reference plane on an OATS facility. Anything from white papers to technical
links are fine. Thanks in advance.

A long time ago I knew of a small company operating along the Colorado Rocky
Mountain front range area that would put up shield rooms, or make
modifications. If that outfit or one like it is still around, could someone
let me know - I do not recall the name. Also if an outfit like that works in
Incandescent light bulbs are only non-linear in that they are a lower
resistance cold than hot, and draw an inrush current. But at any given temp,
they are a purely resistive load. Saturation of the EMI filter means the
inductors of course. The filters should have a current rating that you could

HI Ken,
point well taken. One could arge that light bulbs are nonlinear too... and
waterheaters at 18 kHz That asside, the labs is wired directly to the
building incoming power, 500 volts at 100 amps. I'm more concerned the
facility filters are not saturating under the high current load,
Derek,
MIL-STD-461 requires that the power source be loaded resistively at
the same rms level as the test sample loads it, to perform an ambient.
I realize that 600 60 Watt light bulbs mounted on a couple 4x8 sheets
of plywood isn't a palatable approach, but it is the reason for this
that
One more thing for Case 3 - the values from the tables are for Basic
Insulation. If you have hazardous AC output from the inverter requiring
Double or Reinforced Insulation (i.e to SELV), then the values from the
tables should be doubled.

HI Ed,
yep, I terminated the LISN port when I did the CP test.
At 101 Amps per phase, I cant resistively load the network.
I was thinking that a network amalyser looking into the LISN port ( power
disconnect outside the room ) would perhaps show something impedance wise.

Did you also replace the current probe with a 50-ohm termination, and do you
then not get the hump?
Next, did you try using a resistive load on the LISN's and see if the hump is
there?
Finally, do you still see a hump with just a resistive load and no LISN's?
I would suspect either a
Regarding Case 1 (and any other where voltages do not exceed the limits
in 6.3.1/6.3.2), it may be simpler to apply the fault testing in 9.1a)2)
rather than apply Basic Insulation. Of course a wrinkle would be if your
unlimited low voltage circuit is accessible, requiring you to deal with
the fire
HI All,
I'm watching a MIL STD 461 test on a stand alone EUT. Between 10 kHz and 20
kHz we have developed a Hump in out profile that wasn't present at our last
test lab.
The hump is identical looking with a current probe on the input to and from
the LISN, so I believe I'm seeing no isolation

People have been searching for the Holy Grail for nearly 2000 years, and I
