Grounding Networks

AI Thread Summary

The discussion focuses on the standards related to combining low voltage (LV) and medium/high voltage (MV/HV) grounding networks. Participants note that these systems are typically managed separately due to safety concerns. Combining them could lead to voltage issues during faults, potentially imposing risks on the other system. There is a consensus that specialized electrical engineers typically handle grounding systems, emphasizing the importance of adhering to established standards. Overall, the risks associated with combining LV and MV/HV grounding networks outweigh potential benefits.

On which standard IEEE / IEC BS EN / NEC...we can find recommendation on combining Grounding Networks of LV and MV/HV together?

In general they are handled separately, there are EE ( PEs) that specialize in grounding. I can not think of any good reason to combine them since a fault on ether system will then have V imposed on the other.

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...

Thread 'EMF (Electromagnetic Field) & EHS (Electromagnetic Hyper Sensitivity)'

Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
