[] (Origineel artikel van Geovital.) For underground power lines, assume it carries a medium voltage level unless otherwise marked. Thanking you for any info you may have. Determine if any part of the equipment, load line or load (including rigging and lifting accessories), if operated up to the equipment's maximum working radius in the work zone, could get closer than 20 feet to a power line. READ Also: OHS Meaning What is Occupational Health And Safety (OHS)? Due to the radiation emitted by power lines today, its waveform is much more intense. Each type of line presents a different voltage level to professionals working in proximity to them. You find my online courses for some popular amateur EMF meters on https://healthstronghold.teachable.com The first tip to understanding how to identify low voltage vs high voltage is that at 120V and below, it is perfectly safe to approach power lines (be they overhead or buried) without a personal safety distance, provided you have insulated yourself. Its strength depends on a number of factors, but how much and how strong the electricity is that flows through is significant. 8.7mG is very, very high in our experience. Four voltage classes of transmission lines, 115 kV, 138 kV, 230 kV, and 500 kV, are considered. and which tools should i buy? Sounds like quick action is required here. Is there a way to block the emissions? personal EMF detector to see if your home is receiving the EMF radiation, Redness in skin with itching, rashes, and tingling on the arms or face. Hard to say for sure of course. Seems like if your moral compass says nobody should live there then nobody should live there. It is magnetic fields that are linked to cancers. Youve got the right approach Rayburn. The importance to the operator's safety of remaining inside the cab except where there is an imminent danger of fire, explosion, or other emergency that necessitates leaving the cab. Im not sure how far away they are. Im tempted to pull out. They are so loud that at night in our bedroom I can hear the humming faintly in the distance. If possible, you should definitely go measure the magnetic fields with a quality gauss meter. Is that too close, or am I safe? Answer (1 of 4): The distances between towers on transmission lines is determined by the areas or countries where they are located. Not magnetic fields. An example of one and the same property located near high voltage power lines. You really need a consultant for that. ( Some research shows increased cases of childhood leukaemia within these distances from power lines) Transformer box - 150 meter / 165 yards Electrical substation - 150 meter / 165 yards ( article) TIA, Hi, hard to picture what you are talking about. I am particularly concerned at the variation from one day to the next at a similar time. When electricity flows an electromagnetic field is created that kind of swirls around the source of the radiation like a whirl wind. It is difficult to simply attach a value to what a safe distance might be. For over a year I have been getting hit with what seems like electromagnetic shock. Less than 0.3mG is ideal for the bedrooms at night. Could you please write the name of the Gauss Meter that you recommend, as the page youve given cannot be opened (it says that it doesnt exist). These rules state that no person or object should be within 30 feet of a power line. The problem is the exposure standards of government. Ive started using my Facebook account. For this reason, the exposure during sleep time should be seen as the most important. Address these concerns with your primary care physician on a regular basis. How come it is so low given the short distance? Within months my presence was requested at the Australia consumers affairs office as they claimed we could be taking advantage of people with cancer because we also sold products (solutions) for these people. Night is most important. Ideally it should be 0.3 in the sleeping areas. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. Hi Ashley, thank you for your comment. I would love to cover the windows for her, but this will no doubt stir things up with management. inside downstairs front 0.5 If moving bedroom or house is just not an option then you should reduce all other sources (the common ones) of radiation, in specifically the bedroom, to attempt to make the burden as little as possible. Does anyone know where I can get a device that measures all of what was mentioned in the article? 3 0 obj Now they are changing the towers to run 260KV. need advice, Hi Raghu, Hola Patrick, from south Chile, Taking legal action will be hard or impossible as you will have to prove what governments are actively ignoring or dont want to hear about. Power lines are presumed to be energized unless the utility owner/operator confirms that the power line has been and continues to be deenergized and visibly grounded at the worksite. We put an offer in on a house close to high voltage power lines, but I made it contingent on the EMF reading. and our Thank you for the information! The modeling method is validated using two case studies with field measurements. We need more consultants globally, if you know of anyone interested to do training. We are going to provide some tips and tricks to help you do so safely. Could the (safe) readings inside be accurate? Rainer, Hi Rainer, Regardless, you should get your home assessed because electric fields and radio frequency radiation are common problems. The minimum safe distance from a high-voltage transmission power line that produces a magnetic field over household ambient levels is about 800 feet. could be severely affected. STATE TRANSMISSION LINE STANDARDS AND GUIDELINES Maximum Line Load State Edge R.O.W. If anyone reads this later, go down my timeline on Facebook to 10 or 11th March 2019 to find this video. Good luck. Reddit and its partners use cookies and similar technologies to provide you with a better experience. 2.. The other problem for those realising their health has been affected by something that is perfectly legal, is that by selling it, they are passing the problem to another family who are unaware. Im assuming the roof top is closer to the wires so the number is higher! On other streets nearby, he got readings between 0.6 1.0 mG. My husband and I were concerned about the distribution powerlines very close to our second floor apartment unit so we rented a gaussmeter and were very alarmed to find that in our master bedroom it measured 8.7mg. But the highest is 1.7 and by the windows goes to 1.9? Our Reading arr 38V/m and O.10 uT Normally when we go around power lines etc this thing will make a sound letting us know the danger. Two curves and their empirical models are created for each voltage class to determine the minimum separation distance. Thanks for this amazing and informative Article. Im not a law expert, but I put my answer to your question in video form on my personal website. The risk or occurrence of it is increased, according to those studies. Patrick, Hi I am purchasing a top floor apartment . Have a look at the table below what peer reviewed research has found over the years: Therefore, a reading of just 1 milligauss (1 mG) is the value you dont want in your home. The distances mentioned are more distances in which I strongly recommend you measure your exposure.Hopefully your exposure is at least lower than 1mG and ideally at or under 0.3mG in the bedrooms. There is the small chance that the transmission lines are direct current. Most nations set daily (24-hour) exposure limits to EMF at 1000 mG (milliGauss); the US currently has no set guidelines for EMF exposure limits, citing a lack of conclusive evidence they pose a public health threat. Well answer these questions in this article on how to identify powerline voltage level and safe clearance. Due to higher power consumption, existing power lines generate higher magnetic fields. We may have someone in Tx soon, but we also have people that travel there and do assessments. When uncertain of a power line's voltage, stay 20 feet away for voltages up to 350 kV and 50 feet away for voltages greater than 350kV. As stevenal said: "Cost of doing business." Or; "If you can't stand the pain, stay off the roof." -----Ohm's law Hi Sonja, May I inquire? Hello, I was planning 1 year but may stay 2. Thanks for the comment. Electrical safety and reliability standards require that I am disheartened after reading most of the research out there and want to know what you think of this ? Measure, and you know. ~8.0 mG (vs 10-11mG) at 18m from front. Im finding it so hard to get information on safe distances and strengths around children. Abroad, e.g. You offered below to do a zoom consultation. Things are so busy with us with Corona lockdowns and people wanting to protect themselves against 5G which would likely make it worse. No. Thank you for the comment. Hi Janet, Thanks for your concern. The reading from app in my mobile giving the reading for emf is 110ug ( microgram) please let me is that ok to live in? Measure the EMF outside as well, especially where you like to sit or where children play. If i am designing a primary school, where the electric grid station is opposite to it and the power lines adjacent to the site. Im guessing the effect is linked to long term exposure over an extended period of time or a lifetime. The imediate issue is for a friend working in a big new hospital with power input lines into the building 6 feet from our friends desk! Those looking to purchase and those living near high voltage power lines already, might ask themselves: Normal street power lines are much closer to homes and can cause the same problems are high voltage power lines. If you are working with underground power lines, always wear rubber-soled shoes when digging near them so that if there is contact with electricity running through them, it will travel through your body instead of through soil or water which could result in damage to property or injury to others nearby. My brother in law has started having seizures of sorts. My first thought was the high voltage transmission lines behind his house. Those field often reduce much quicker. The type of power line that comes in communication with home and commercial buildings is known as a distribution line. Hi Tony, sorry for the delay. The radiation from other sources (wiring, phone towers etc) will need other better meters. Knowing what I know now, Id take care of what I need to do with Geovital first. I am concerned about that not only the devaluation of the property and surrounding properties but the health Factor as well. You can purchase a quality gauss meter to investigate just these fields (TF2 not a bad choice), or get a consultant to assess this and the other more common sources of radiation in a home. You need a good quality guass meter, like a TF2 meter and probably do our online course to know how to use it and interpret it better than you would without it. I can hear the electricity surge through it when I have the bedroom window open, and Im in the basement! When working near transmitter/communication towers where the equipment is close enough for an electrical charge to be induced in the equipment or materials being handled, the transmitter must be deenergized or the following precautions must be taken: The equipment must be provided with an electrical ground. The link has been fixed, thank you. [], Hi, If you see anything or anyone that violates safe clearance measures, you should report it immediately. You should get it investigated by a professional and at the same time assess or address the other more typical EMFs in a home. That would mean your measurement indicates a reading of just 0.11mG which is far below our recommended 0.3mG or less for bedroom environments. Great to hear my online course has helped you and youre obviously approaching homes with a lot more confidence. Have a look. Hi Patrick, thank you for such an informative article. Please consider buy my online course for the TF2 with it so you are confident on how to use it. Greetings from Spain. The strength of low frequency electromagnetic fields is expressed in milligauss (mG) or nanoTesla (nT) or other values. I'm interested in hiring someone to do an independent test before we make an offer. We are looking at property to build on, its about 600 feet from overhead over lines. The general rule of thumb is that for overhead lines, you should maintain a distance of at least 10 feet from their poles and 25 feet from their wires. Footnote (1) Enter the maximum anticipated per-unit transient overvoltage, phase-to-ground, determined through an engineering analysis or assume a maximum anticipated per-unit transient overvoltage, phase-to-ground, in accordance with the following table: Occupational Safety & Health Administration, Occupational Safety and Health Administration, Outreach Training Program (10- and 30-hour Cards), OSHA Training Institute Education Centers, Summary and Explanation of the Final Rule [PDF 2MB], Severe Storm and Flood Recovery Assistance. Are these numbers safe?!! Secondly, power companies will not cross over each others lines if at all possible. Hi Tandy, Heat Exhaustion Recovery Time How Long Does It Take To Recover From Heat Exhaustion? First, 11 kV is basically a distribution voltage level. Hi Patrick, I found a house close to a distribution line in backyard and a tower close by. 0.3mG (=30nT) or less is ideal for the bedroom. Tram lines can definately be a big source of magnetic fields which are linked to melatonin being blocked in its natural anti-cancer action. That is so close. Having a 220KV transmission tower anywhere in a school is absolutely foolish. Ive had nothing but health problems my whole life. With my Trifield 2 Ive measured 6.36mW/m2 in the kindergarten play area. I noticed in the 18 months we were there, my lump increased in size and my immune system was weakening as I was catching colds while the rest of the family wasnt. I have for you, answered your question in a video which Ive just uploaded. After identifying voltage level, you need to determine safe clearance distances. Chronic complaint, fertility problems as well as cancers could be caused. Second, if you plan to construct a house close to this distribution line, it has to be outside the right of way (easement) boundary of the line. Hi Patrick, Faraday cage would help at something? The problem with magnetic fields is that you cant really shield against them with something that is effective, affordable and has a chance of success. You purchased a home, not knowing about electronic pollution and environmental health burdens, or perhaps you didnt think this was a problem. It also has a tolerance of 15%. I need the details of safe distance to construct house near the power transmission lines basing KV rating of particular line. We are a young family with 2 young kids, so dont want to risk it if not. Regardless if you build here or elsewhere it is wise to do things right from the start and not create the same problems we keep finding in other homes. People are becoming more aware that properties near high voltage power lines, as well as mobile phone towers (article), are getting harder to sell unless the vendor is prepared to reduce the price. Try and find out from the power company if that is the case. More importantly, different areas have different rules for safe clearance from power lines. Thank you for your answer. The lines with high voltage transmission lines of 400 kV create less than 0.5 milligauss at a 200-meter range. Two-phase lines can carry 60 kV on one phase and 115 kV on the other phase. Amps is usage and guess what they tends to increase over time. An insulating link/device, as defined in 1926.1401, installed at a point between the end of the load line (or below) and the load. The sub tenant doesnt know about the readings. <>/ExtGState<>/XObject<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 612 792] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>> If you come across a line and arent sure if its a power line, do not assume it is not! Look after yourself and do what you feel is right. My question is, can I use your products to help make the house safe? But before moving here we measured the magnetic field and surprinsingly it was 0,01-0,02uT which is 0,1-02, milligause I suppose. For overhead lines, if you come across a line that does not have any markings or labels, assume it carries a high voltage level. At 0.11mG this is a very low reading we dont see often in homes near normal suburban streets. When you say in this article that a Transformer box should be measured for its levels if they are within 150 meter / 165 yards- are you talking about those small transformer boxes that sit on front lawns or are you talking about a larger box? Such a device must be set to give the operator sufficient warning to prevent encroachment. READ: PAT Testing (Portable appliance testing) - All You Need To Know The occupants are tenants, renting but will find it difficult to get another similar accomodation at the same price. I dont think the noise and EMF radiation reach need to be related. Im concerned with possible health effects like childhood leukemia. Voltage (kV) Minimum clearance distance (feet) Up to 0.75 kV. In transit with no load and boom lowered, the equipment clearance shall be a minimum of 4 feet for voltages less than 50 kV, and 10 feet for voltages over 50 kV, up to and including 345 kV and 16 feet for voltages up to and including 750 kV; 1926.550 (a) (15) (iv) I wont be able to measure with the gauss meter until the lines are put in later this year. 4 ft. 4 in. Yes it can be and anything wrong with the wiring in a home can cause terrible exposure. How about a swimming pool that is 200 feet from the high voltage lines? It is a concern also I noticed and observed my body beginning to tremour at another house, in the front bedroom, where I know the readings are above 2 milligauss due to the power draw of the owner in her bedroom with an electric blanket, a tv and receiver, a cordless phone, a router for the internet, an emergency alarm. Good luck. I dont like your chances on health/radiation grounds. I appreciate your honest and informed advice. Sara. But before you panic, MEASURE first. We are in Spain where there are no consultants. Most power lines in North America are at 115 kV, but 230 kV is also common. Hi Shari, So, whether for this home or any other, you should have that assessed by a professional. Hi The problem is amps. The calculator provides the minimum approach distance, in feet or meters (depending on your selection), for phase-to-ground and phase-to-phase exposures. When it comes to identifying dangerous power lines and ensuring a safe clearance, three types of power lines come into play: transmission, distribution and communication. 1926.1408 - Power line safety (up to 350 kV)--equipment operations. We were back at the house and measured ~25.0mG on the street and with numbers inside the house over 1.0mG. After roughly 80m (260ft) away the EMF from the overhead line is negligible against the background levels. If you see a sign that says High Voltage or Warning: High Voltage it is best to call an expert before proceeding with any further investigation. Your electrical powerline is delivering up to 120,000 volts of electricity to your home or business right now! Erect and maintain an elevated warning line, barricade, or line of signs, in view of the operator, equipped with flags or similar high-visibility markings, at 20 feet from the power line (if using Option (2) of this section) or at the minimum approach distance under Table A (. I am over 80 and not to up on computers Very interesting to read. Often at night these reduce further. The total voltage of a two-phase line equals 230 kV (230 kilovolts). I have to wonder if thats why people have been so crazy here as well, even the landlord who lives two floors above me is absolutely out of his mind sometimes. I would love a consultation if there was anything that can be done to correct this? You cant shield against magnetic fields and they have been linked to cancer in multiple studies. My electric company in Texas is putting in 138Kv lines about 300 feet from my house. We have 3 kids 2 6 yr old and a 3 yr old and I am worried for their safety. The first step in learning how to identify voltage levels is identifying which type of line you are looking at and whether it is above or below ground. I recently examined no fewer than TWELVE possible housing options for my college age daughter, using my amateur tools to measure emfs and to look for possible mold issues. Provided the meter is accurate, that would be one of the worst homes Ive come across. I have children and dogs and I recently was diagnosed with breast cancer. Good luck endobj We live 80 meters (260 feet) from huge power lines. In Australia, the minimum clearance distance from the centreline of 275kV transmission lines is 25 metres (~75ft). For equipment with non-extensible booms: The uppermost part of the equipment, with the boom at true vertical, would be more than 20 feet below the plane of the power line or more than the Table A of this section minimum clearance distance below the plane of the power line. Is there a source for your products in Chile? Finally found a place for her, but I worry about the hundreds of other college kids exposed to obscenely high levels. Sanya. All our shielding products address either electric fields or radio frequency radiation. Iam also very hard of hearing and cant tell if the slight roar is The terrain has a major influencing role. You may be shocked to find out how many homes are affected by this and that many of those homes are nowhere near those big high voltage power lines. Power lines also throw of electric fields if above the ground. Upstairs bedroom rear of home steady 0.2mG (thought I was measuring towards front of home but got mixed up with realtor starring at me like Im nuts!). If it is a pipe, it runs the whole length of the road. This is something I would expect theyll fight tooth and nail as it would pull into question every house that currently is already so close that there is cause for concern. Or is there a formula that can be used to calculate the electromagnetic radiation to see if the distance is safe? If tag lines are used, they must be non-conductive. Patrick. It is best to hire an expert when calculating such levels of distance. Hi Bob, short answer is no, sorry. Many people would wonder, when looking at homes near high voltage power lines, if those can be bad for you, or even cause cancer. It is electricity that produces the radiation, so its the cables that it comes off. Then Id sell the house. Do you think it is safe, and what would you advise? We are looking at another home with underground power cables. Front door +/- 1.0mG There are power lines behind our back yard that carry 130KV. (I accept no liability on that assumption readers its just an assumption, a gut feeling, and may not be right or right for everyone) Good luck Pam. But, given what you describe, it sounds like magnetic fields may be high and you cant shield against them so measure first and then assess if its a good long-term strategy to stay there under those circumstances. A TF2 is a good amateur meter. The thing to remember is that your sleep is your key regenerative time the time when your body is supposed to fix itself. Magnetic fields is what you need to measure. Give me a few days, were teaching online this week http://bit.ly/2hOgAmf I think it is a problem with the underground power line and perhaps it has lost insulation or is spliced. The requirements of paragraph (b)(4) of this section do not apply to work covered by subpart V of this part. now I can feel vibration lying in bed and lately on the floor in other areas as well. Find out IF the exposer levels are what we would say is concerning and if so perhaps you can adjust the placement of the building (pull it further away). What about Mu-metal? Just keep in mind that electric fields from wiring is often a problem but most amateur meters cant assess it properly. You cant do both. What is the closest you would feel comfortable living, Hi Craig, Some of our consultants can help with that. The ongoing exposure to EMR can slowly start to ask its toll. They put a school right under them on other side of me Im just outraged. 1.2 Meter. The electrical resistance and power rating of the transmission line varies based on the conductor. Contact us via usa (at) geovital dot com with your details and we can try to find someone for you. Hello Patrick I live in a14 story bldg of 147 apts I am on the 6 floor and the bldg has 2 high power towers on top. This power line is not even 20 feet away from my bedroom. . Is there anything I can do to reduce or eliminate the noise and/or EMF or its effects? Where necessary, use equipment that enables the dedicated spotter to communicate directly with the operator. The uT (microtesla) reading will be the magnetic field value. How close is too close when it comes to high voltage power lines, and how are our children affected? Exposure can also vary during the day, so measure morning, day, evening and night too. due to the power line or something else. The procedures to be followed to properly ground equipment and the limitations of grounding. Homes are plagued by electric fields and radio frequency radiation as well, but this can normally be addressed just nicely through a proper assessment and products that are well designed solutions. The employer must train each operator and crew member assigned to work with the equipment on all of the following: The procedures to be followed in the event of electrical contact with a power line. The house is on a road that is crescent shaped. In some cases, 115-kV lines are used. They will also know how to apply for special exceptions with your states agency that oversees electric power lines. High voltage power lines can be problematic at far greater distances, but small street power lines can also produce similar problems. Communication lines, also known as telecommunication or telcom lines, are responsible for transmitting telephone and cable signals to homes and businesses. Sounds like this house has a problem and you should tread carefully. OHS Meaning What is Occupational Health And Safety (OHS)? Measure the same locations at different times of the day. Noise will travel much further. (Types, Pros, Cons, Alternatives). It made it really difficult to decide if the property is safe or not. What do you recommend as the next step? I had EMF inspection done with below readings. We used to do a few free home assessment each month for people with cancer. Brushing off the situation as a Buyer Beware situation doesnt seem entirely justifiable, what do you think? Reading zero. The higher the kV number, the higher the voltage level. As a result, Table A-4 Minimum Approach Distances shall apply. Anything over 1mG Id take very serious. Good luck. Everyone I have spoken to who has invested in it, wish they had not. Plus i am concerned that at some stage they might up the voltage of the lines!! Good luck. What do you recommend I do? I live about 5 blocks from train tracks. (''Transmission Line Conductor Design Comes of Age'' by Art and 400 kV, connecting more than 300 substations. Im guessing if I can actually audibly hear the hum from my bedroom, then EMF from the cinema would be reaching my bedroom as well? Ive answered a similar question and the relationship with shielding paint on my personal site: https://www.healthstronghold.com/video-qa-shielding-paint-magnetic-fields/ - Blij Stralingsvrij, https://www.healthstronghold.com/video-qa-shielding-paint-magnetic-fields/, https://www.healthstronghold.com/video-qa-developer-liabilities-selling-land-transmission-lines/, https://www.healthstronghold.com/living-near-power-lines-004/, https://en.geovital.com/the-new-tf2-trifield-gauss-meter-as-tool-for-the-amateur-product-review-test/, https://www.facebook.com/Patrick-van-der-Burght-1996353220673771/, Ethernet over power line (EOP/Powerline) the dangerous internet from the power point. I lived in a house across the street from a hydro field for basically the first 13 yrs of my life. ,i@6-}Ya#0t(#B%9H8t |r:wfM3BFZm1P Unless not much is going though, I think youll likely be exposed to magnetic fields from them. I would say medium sized ones . So how do we bring awareness and fight the builder from continuing to build so close ..? So we went in and the number fluctuates! Find it here: https://bit.ly/2YHucCh, Hello, As a result, the following Table A-2 Minimum Approach Distances shall apply. Patrick, Good Day! (Was only aware because I have another child with autoimmune issues.) 210 C (410 F) and 230 C (446 F), respectively. They intend to place 88 of these towers approximate 10 mile radius. I can say this when it comes to other apartments being under the same roof and exposure: Be careful announcing your findings People have threatened to take legal action because one home owner started raising the alarm which may affect the property values. Line passes above or adjacent to any building or part of a building. Dont rely on a calculation. Ive tried to answer your question by video. Give timely information to the operator so that the required clearance distance can be maintained. In a distant past Patrick van der Burght gained experience in real estate. Reasons why radiation in power lines exist: Does Hematite protect from EMF radiation?
