(electricity)
An iron-core transformer having a primary winding that is connected to an alternating-current power line and one or more secondary windings that provide different alternating voltage values.

Transformer, Power

 

a transformer that is used to transform AC power in power system networks, radio apparatus, and automatic systems. A power transformer operates with a constant effective voltage. The frequency of power-transformer current in most countries, including the USSR, is 50 hertz (Hz); in the USA and some other countries it is 60 Hz. Power transformers are the most common class of transformers. Transformers have been built (1975) for a power of 1300 megavolt-amperes and a voltage of 750 kilovolts. (For more detail, see.)

power transformer

In an alternating current electrical system, a device for transforming the source of electrical supply from one voltage to another.
