Have you ever wondered what the big green boxes are on your farm, around schools, or even in parks? Well these big green boxes are called transformers. The responsibility of a transformer is to take the lowered voltage that is coming from the distribution lines and lower it yet again. By lowering the voltage again, the transformer is making it safe for the power to connect to your home. Not all transformers are on the ground like the big green boxes we see. Transformers can also be mounted to pole tops!
