What is the problem of taking a house near a transformer?
When we were planning to purchase our second home, our Finance consultant suggested to avoid house that has any transformers around as the banks /lenders may create issues with it. I tried to google about it but din’t find much info.
So , I did a bit of research, spoke to some of the council guys and Electricians and found out the following info and would love to share it with you all.
One of the most significant benefits of Buying a new double-story home is that customers can have space for enough bedrooms, living areas, outdoor rooms, studies and storage.
By going up, you are maximising your new home’s footprint, rather than chewing off space from the front or back yards.
Many buyers will opt for a two-story home to maximise living space on a small Land.
Is it safe to have a home near a transformer?
Electric box is in my yard. SAFE or NOT?
Setting an effective budget before Buying a double storey home in Melbourne or other Australian regions can be difficult for inexperienced builders.
Use a ‘budget planner’ system to compare the total cost of building your new home (including the land) with comparable homes for sale in the same area.
As a result, budget planner calculations can provide you with a general idea of what your new home may be worth when completed. It’s a wonderful feeling to know that your initial investment was sound and will pay off in the long run.
When creating a budget, keep these two common blunders in mind.
Overestimation of expenses: Overestimation of finishing costs associated with completing the home can quickly add up, causing unnecessary stress as the project nears completion.
Overspending: Avoid splurging on luxuries that add aesthetic appeal but do not increase the value of the finished home.
Purchases of luxury materials that are not valued by others may result in a loss when the time comes to sell the home.
How dangerous is electrical transformer for human health if it is near to house?
Power lines and other electrical sources are not far from where I want to live or work.
Magnetic fields generated by power lines, substations, transformers and other electrical sources have not been shown to cause any health problems. It’s possible that extended exposure to greater than normal magnetic fields may raise the incidence of leukaemia in youngsters, according to epidemiological research.
As the amount of current carried by a high-voltage (HV) powerline increases, so too does the amount of magnetic field exposure for residences located near the powerline.
For residences more than 50 metres away from a high voltage powerline, magnetic fields are predicted to be lower than usual. Magnetic fields at distances of 5 to 10 metres away from substations and transformers can be indistinguishable from usual background levels in the house.
The magnetic field levels observed by ARPANSA near powerlines and in Australian residences are shown in the image below. These are significantly below the worldwide recommendation of 200 T, which is a safe level of exposure (2000 mG).
This transformer sits atop a 14,400 volt underground power line near the edge of my three acre property.
It is wired to supply my home with up to 200 amperes of current at 240 volts through an underground conduit. Since that transformer is capable of supplying far in excess of what my house will ever need,
It’ll never be overloaded because 200 amperes at 240 volts is just 48,000 volt-amperes.
That is less than one-seventh of the transformer’s maximum capacity. Not surprisingly the transformer never even gets warm. Its excess capacity allows it to deliver a full 120+ volts or 240+ volts to the power outlets in my house no matter how many electrical devices I’m using. I believe that transformer installation ADDS value to my home. It certainly does not diminish it.
What are the Dangers of pad-mounted transformers
Transformers should always be accessible.
If a pad-mounted transformer is in a public utility easement across your property, please keep an eight-foot walkway open in front of the unit. The transformer’s entrance opens at the front, and it is padlocked.
Make sure you don’t block the transformer’s front. Fences, plants, trees, and storage sheds are examples of obstructions. Any impediment can:
Create safety hazards for employees attempting to get access to the transformer.
Service restoration should be postponed during power interruptions.
Problems may arise during ordinary equipment maintenance.
It is a requirement of the many council Utility Service Regulation to provide City staff with safe and unimpeded access to its electrical equipment at all times.
Keep an eye out for Transformers.
Avoid coming into touch with a pad-mounted transformer for your own safety. Also, never let your youngsters play on or around transformers.
If there is a transformer box close to a house, how much value will the house lose?
Do transformer boxes decrease property value ?
Transformers are often located in the rear of a property’s utility easement in areas with underground electric lines, as is the case in my neighbourhood.
On the other hand, at my cousin’s house in Austin, the boxes are being placed on the front land between the houses.
My best estimate is that the utility easements are located in front of the residences. They appear a little awkward from the front.
In the absence of other considerations, I would prefer not to have a value deduction in front of my name. A few feet away, in the front yard, is another.
Older homes in the United States are powered by wires strung from wooden utility poles to the dwelling.
A transformer (or possibly a set of transformers) will be installed high on one of the poles, converting the higher voltage of the local grid (about 1500V) to the residential voltage (240V). About 10 to 15 dwellings are served by a single transformer.
Newer dwellings in newer developments will get their power from a transformer (or set of transformers) in a ground-level cabinet via underground conduit (which receives a 1500V feed from the grid – probably via underground cables that eventually connect to an arial system on poles at the border of the development.).
The cabinet is likely to be somewhat hidden by some landscaping, although the electrical distribution company has a “right of way” in order to access it.
The underground conduits serving the individual homes will also involve a right-of-way for servicing, etc.
The arial system also involves rights-of-way so that the electrical distribution company can access the system.
For neighbourhoods served by a arial system, the rights of way impacts almost every property (except a few edge cases.)
I doubt that it’s possible to determine a specific “loss” for any property – the proximity of the electrical cabinet (or transformer) could even be considered a positive as any repairs involving the connection to the nearby house would be easier to coordinate and perform.
The other differences in homes, landscaping, location, condition, etc. are far more significant.
Anything that detracts from the home’s appearance will lower its worth, especially if it’s visible from the street. Furthermore, some people will be concerned about the possibilities of electric and magnetic fields, which some believe might cause cancer.
However, if you can get a good deal on a house, you might be able to buy it. You’ll almost certainly provide the same discount every time you sell. Seek the advice of a skilled local real estate agent.
How much radiation is emitted from a pad mounted transformer box, and is there any risk for kids to live in a house that has one in the yard?
Does the usage of electrical appliances have any negative impact on one’s health?
The neurological system can be affected by high amounts of ELF EMF exposure. In contrast, significant amounts of ELF EMF from electrical sources are not often encountered in the common environment.
Although these exposures are extremely rare, there are worldwide rules on exposure limits that are designed to prevent documented negative consequences.
Exposure to ELF EMF from electrical sources below the exposure limit has been the subject of extensive investigation.
ELF EMF exposure in the environment, especially near power lines, does not pose a concern to human health, according to the vast majority of studies.
However, several epidemiological (population) studies have indicated a probable link between long-term exposure to ELF magnetic fields at levels below the exposure limits but greater than what is commonly encountered and increased incidences of juvenile leukaemia.. International Agency for Research on Cancer (IARC) has classed ELF magnetic fields as potentially carcinogenic to humans based on this data.
Electricity and health
Power lines, substations, transformers, ordinary electrical appliances, and wiring all produce extremely low frequency (ELF) electric and magnetic forces (EMF).
We are continually exposed to ELF EMF because we live in an environment that is always surrounded by electrical sources. It is feared that exposure to low-frequency electromagnetic fields (ELF EMF) might produce health problems, such as leukaemia in youngsters.
Maximum distance from transformer to house
Aluminum triplex cables will be used for 240/120V drops from pole mounted transformers to dwellings in the United States.
The standard maximum length is 150 to 200 feet. Any longer than that will result in an excessive voltage loss when under heavy load (A/C, cooking, lighting, etc.).
The electricity provider will attempt to instal a pole in an alley and then drop to at least four houses all within that maximum length. In typical residential sizes, #2 Al is rated for 150 amps and #2/0 is rated for 200 amps.
Transformers are usually protected, and there isn’t much magnetic dispersion.
The main issue is a hum at twice the grid frequency, which is relatively low frequency but can cause a glitch in the audio spectrum, as well as vibrations from large transformers. The frequency is too low to cause significant disruption from an EM standpoint.
