Incredible amounts of electricity is created at power stations and sent across the country through wires that carry unbelievably high voltages. All power lines radiate electromagnetic fields. The question is: how much are the power lines near YOUR home radiating? The amount of "EMFs" coming from a power line depends on its particular configuration. Power companies know which power line configurations are best for reducing EMFs but most don't feel the evidence supports costly changes in the way they deliver electricity. Is that ok with you?
A substation is an assemblage of circuit breakers, disconnecting switches and transformers. A key component of a utility's electrical distribution network depends upon numerous, small transformers mounted on power poles. A transformer looks like a small metal trash can, usually cylindrical. We've all seen them.
Even when the electrical service is underground, you will often see a metal box (usually square) located on the ground near the street. Many people don't realize that when they see a transformer, the power line feeding the transformer is 4000 to 13,800 volts. OMG!
