AI Thread Summary
The discussion focuses on finding protective relays for a 3-phase 120/208 volt generator system, specifically avoiding electromechanical output relays due to their shorter lifespan. The user seeks relays with adjustable trip and reset times, requiring features such as overvoltage, undervoltage, overfrequency, underfrequency, loss of phase, and overcurrent protection. Modern relays that combine multiple functions into one unit are preferred. Recommendations include contacting suppliers to discuss concerns about relay longevity and to obtain suitable options. The conversation emphasizes the importance of selecting durable and multifunctional protective relays for optimal generator system performance.

I am trying to get the necessary protective relays for my generator system and I do not want to use relays with a electromechanical output relay as this does not last as long. I am trying to locate these and am having some trouble with it. Is there anyone who knows about this?
The following relays will need the following specs:
3 phase 120/208 volt system prefer no coil voltage necessary but 12/24 volt if necessary.
Adlustable trip time and adjustable automatic reset time. Need two poles each that open on fault.
Overvoltage
Undervoltage
Overfrequency
Underfrequency
Loss of phase
Overcurrent

Modern relays often combine several of those functions in one relay. For example: https://cdn.selinc.com/assets/Literature/Product%20Literature/Data%20Sheets/710_DS_20190508.pdf?v=20190614-202607

You should contact your suppliers, explain your concern about lifetimes, and listen to their recommendations.

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...
