AI Thread Summary
The discussion revolves around the configuration of 132kV transformer incomer current transformers (CTs) with a specification of 900-600-300/1-1-1-1-1A and a total of five cores. Participants question whether this indicates a single CT package or multiple separate CTs. There is a suggestion that reaching out to the original source of the information could provide clarity on the topic. The conversation emphasizes the importance of understanding the technical details for proper application. Engaging with the author of the paper is considered a potentially intelligent approach for deeper insights.

what is meaning of this ?

132kV Transformer INCOMER CTs
(900-600-300/1-1-1-1-1A)
NUMBER OF CORES - 5

is it single CTs package or different CTs ?

Would it be intelligent to ask the person that offers that paper ?
 
this is copied from internet for learning purpose .
 
Yes, I know where You found that. For details would it be intelligent to ask the person who put that on the internet for whatever reason ?

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...
