# Does a transformer need clearance?

Contents

## What is the minimum clearance between transformer and walls?

Transformers should be located at least 12 in. to 18 in. away from walls and other obstructions that might prevent free circulation of air through and around each unit, unless the unit is designed for wall mounting and installed per the manufacturer.

## What is a safe distance from a transformer?

200 meters is a good safe distance, which usually ensures values corresponding to the population average. Depending on the loads served by each line you can record normal levels of magnetic fields even 50 meters or less from the cables.

## How far should a transformer be from the house?

While it may be tempting to “camouflage” transformers with landscaping, please remember cooperative crews need at least 10-feet of clearance at the opening of a pad-mounted transformer and four-feet at the rear and sides of the housing.

## How far can a panel be from a transformer?

It’s a given that the accepted standard clearance for electrical panels is 3 ft, but that doesn’t answer your question. Generally, concerning both transformers and panels, distance is a good thing, and the more you have, the better.

## Is it bad to live next to a transformer?

Transformer substations located close to the living areas could induce high long-term exposures to extremely low frequency magnetic fields of nearby inhabitants. Some of the researches have shown increased risk to childhood leukemia associated with the long term exposure to the elevated levels of magnetic fields.

## What is the minimum distance between dry type transformers?

Energy Efficient (EE Type) Ventilated Dry Type Transformers must be installed so that a minimum of 3 inches clearance is available between a ventilation opening and any wall or other obstructions.

## What is the distance between two transformers?

## Do transformers give off radiation?

Recent studies in England have shown that these transformers generate an electromagnetic field (EMF), which can cause cancer. Electrical transformers are a big source of EMF with extremely low frequency electric and magnetic fields surrounding it.
