Electromagnetic field generated by a recovery station 20kv

  1. Nov 25, 2014 #1
    hello engineers, i have a question .

    what effect would a recovery station that is power at 20 KV and 50 hz from the local power line would have on the immediate area around it? i mean i know it will produce some electromagnetic field around it, and that is not that good for the rezidents living next to it. I know that those things should be built NOT in a rezidential zone...they need it because they extend the infrastructure of the public transportation sistems .

    The station is being built at max 5 meters from a house and there are houses all around it. I know that it's not HEALTHY for the inhabitants of the area. What i`m asking is, is that station a health hazard for the inhabitants living next to it? (i dont know what data i need to know in order to calculate the intensiti of the field at difrent points around it, and even if i knew how to do that , wich i will find out, i wouldn`t know what intensiti is damaging over time for the healt of the people)

    The person living at 5m from that station already sued the local city hall..well not city because we live 10 km from a citi and we have a local hall, but the thing is i dont know if he`s gonna win the case. I live 3 houses farther away from the station so i have a particular interest in that case. IF this is a health hazard i will support and make sure he wins the case. BUT in order to do that i need to make them REALIZE WHY they should support me (to explain i need to understand it myself, that`s why i`m asking for your help) ...please if some1 could answer this post you will help me and my community greatly.

    i forgot to mention, i can find out any tehnical data about the station if you need more then i have supplied here to calculate the field and know the effect it`s gonna have over time regarding the civilians in the rezidential zone near it

    How do you KNOW that it is not healthy for the inhabitants of the area? If you know this then what are you asking from engineers?

    i know that those kind of stations produce some fileds around them while active, right? what i dont know is what is the value of that field, and what dose that value mean regarding healt...my bad english is geting in the way of understanding me :( i hope you understand what i want to say....

    i know that the strenght of the field is the force divided by the charge...what i am asking is HOW MUCH damage can a station like that do to people...if any at all...and what dose that value means regarding healt..like..what happens with a humanstanding a electromagnetic field of x intesity, or power, or whatever is that influences the human....without knowing this i can`t make a big fuss about it... i need to do my "homework" about this case...and i can`t do it alone because i don`t have the knowledge of an engineer...yet...(i am studying electrical engineering at the moment). you can use tehnical terms to explain, i can understand anything you say no matter how complicated you make it sound...

    Biological cells and tissues are not particularly affected by EMF, particularly of low frequency.

    so you are saying that i shouldn`t be concerd about healt hazzards from it..?

    dosen`t it affect our brains in some way? since they use emf too? sorry if my questions are impertinent...

    Not "impertinent" but without foundation, presuming facts not in undisputed evidence. Our brains do not use EMF.

    "Your brain is electric. Tiny impulses constantly race among billions of interconnected neurons, generating an electric field that surrounds the brain..." :" http://www.scientificamerican.com/article/neural-feedback/"....this is what i mean by "use emf"..i didn't correctly express myself, again..

    But i get what you are saying...so it`s safe to say that it dose not affect us in any harmful way ...

    Nerves transmit chemical potentials, imbalances of ions, and with sensitive enough detectors that electric field can be detected and, with a large enough imposed electric potential, the processes can be disturbed - think electric shock.

    Commercial popularized publications are intended to generate further profits and not to educate. In about 1968 that magazine published an article hypothesizing HTLV-III transmission by mosquitoes in Belle Glade, Florida, that was sufficient impeachment for me.

    "Commercial popularized publications are intended to generate further profits and not to educate". this is very important to me, i realize this and i need to know where to get my info from, places that want to educate, can you please recomand me a list of such places? if they are internet based databeses that would be awsome , books are good too, or anything . In those times it`s hard to filter the good info from the bad one. i dont wanna "presume facts" but i need to know where to get my facts from...what would i need to learn in order to be able to make good decision making regarding things like this? (i know critical thinking is a big thing...i say this with shame, but i didin`t really study it, i just know it exists and have some basic , unfounded (so probably wrong) intuition about what it means... you are a great help sir, thank you for replying and for the patience you acord, i hope i don`t get frustrating with all the questions...

    5 meters from house is pretty close. But still, you should expect damage mostly to one's eyesight... it is ugly to have such substation so close to the place where you live. Associated low frequency magnetic fields are too weak to cause health hazards. Also E-fields of 20 kV equipment are too low to create risky concentrations of bad ions in a neighbourhood.
