Could you please advise if a residential electricity transformer is hazardous to health? The transformer is adjacent to the house boundary wall, and according to the council it is of low to medium voltage, oil- cooled type, enclosed by a 7ft high 190mm cement block wall which also acts as a firewall;
The transformer (or is it a substation?) is about 2metre long x 1.5 metre high x 0.5mtre wide.
I have pictures of the transformer but did not know how to upload them with this message.
Any information or insight you can provide would be appreciated.
Thank you,
Greg |

Hi Greg
This sounds like a standard electrical substation (which "transforms" the electricity from the grid to the consumers). It therefore is hazardous in the same way that all substations are - rather than me giving a very long detailed answer here, please refer to the article "Powerlines and Substations" in the subscriber article section. You may also find "Power Frequency EMFs and Health Risks" and "Powerfrequency Protection for you and your family" useful. |

Hello,
Thank you for the information. I will buy a metre to measure the field.
I have since found out the transformer / substation is about 11 KV. Is this small enough to pose little or no danger form 1-2m away from it?
Thank you,
Greg |

Hi Greg
It really is best to measure the fields as they can vary so much from one substation to another. You can either hire or buy an instrument (you'll need a PRO or equivalent)
Best wishes

Magnetic fields from 11 kV substations come from both the equipment and from the underground cables feeding power out to nearby houses.
Fields generally fall off within 3 metres. Some are OK at 2 metres and some (relatively few) terrible at 5 metres away - usually from the cables in this case.
Only way to tell is to do measurements. |
