Transformer information and costs by email,
from Havertown, PA

The ratio of the peak voltages and peak currents in the primary and secondary windings are determined by the ratio of the number of turns in the primary and secondary windings.  The latter ratio is usually called the turn ratio of the transformer.  If the secondary winding contains less turns than the primary winding, the peak voltage in the secondary circuit is less than that of the primary circuit.

There a primary circuit and a secondary circuit.  There is no connection between the two circuits, but each of these circuits contains a winding, which links it inductively to the other circuits. The windings are wound onto an iron core.  The iron core channels the magnetic flux generated by the current flowing around the primary winding, and as much as possible, also links the secondary winding. This type of transformer is called a step down transformer. construction, primary, Delaware County, Delco, Philadelphia, PA, secondary, 4160, 13200, three phase, 480v.
