The working principle of transformers is based on Faraday's law. Electric current, while passing along the cable, generates an electromagnetic field. This field, in its turn, applying the effect of inductivity, can create a current in another wire that has been placed in the area of reach. EMF strength depends directly on the length of the cable (that's why windings are utilized in such devices). The value of voltage can be altered while transferring the current from one winding/wire to another. Transformers are commonly applied in automated systems in both switchboards and control panels.
