Definitions:

Single-Phase Transformers

Transformers designed to operate on an electrical system using a single alternating current (AC) phase, commonly used in residential and light commercial applications.

Primary Line Voltage

The voltage applied to the primary winding of a transformer or the initial voltage in a power distribution line before any step up or step down transformations.

Secondary Line Voltage

The voltage present in the output (secondary) side of a transformative device, typically less than the input (primary) voltage.

Turns Ratio

The ratio of the number of turns in the primary winding to the number of turns in the secondary winding of a transformer.
