This immunity set up problem seems like the exact likeness of an emissions problem. The (as you correctly state) complex problem of what to do with cable was eventually congealed in ANSI C63.4 with pictures on how to set up an emissions test. Given that the physics of emissions and currents on

I haven¹t seen anyone respond to this, so I¹ll take a crack at it. Not authoritative though in terms of quoting chapter and verse from EN61000-4-3. MIL-STD-461 using 2 cm cable separation is heritage clear back to the early 1950s, and has nothing to do with radiated immunity testing. If it were

Steve, I've dealt with plasma generators before, in my case atmospheric plasma for cleaning. Unless the plasma wand is under some form of robotic control I would not think this is not machinery. And in my view it is not an arc welder. What I used in the past was use EN 61000-6-2 and EN 61000-6-4

[PSES] Cable Arrangement and Separation in EN 61000-4-3 Radiated Immunity Test

2019-08-01 Thread James Pawson (U3C)
Hello experts, I am performing some testing on a control panel with multiple cable connections and it has got me thinking about the radiated RF immunity testing. I know from the EN 61000-4-3 standard that "1m of cable is exposed to the electromagnetic field" in the Uniform Field Area (UFA).
