Definition For Power Transformers
Transformers are most commonly used for increasing low ac voltages at high current a step up transformer or decreasing high ac voltages at low current a step down transformer in electric power applications and for coupling the stages of signal processing circuits.

A power transformer is a static machine used for transforming power from one circuit to another without changing frequency. The stepping up or down depends upon the number of turns of primary and secondary winding. Power transformer is an electrical device that converts inbound electricity to a higher or lower value of voltage for specific purposes. Transformer operates on an ac supply.
Now since iron losses depend on voltage and copper losses on current the total losses depend on voltage and current and no power factor is involved. If the number of. It is a major component in power grid to supply voltage in many nations. Transformer size insulation level.
Transformers are rated in kva as kw would include power factor. When we talk about transformer we have two kind of losses iron loss and copper loss. This is a very basic definition of transformer since there is no rotating or moving part so a transformer is a static device. It is also used in isolation transformers earthing transformers six pulse and twelve pulse rectifier transformers solar pv farm transformers wind farm transformers and in korndörfer autotransformer starter.
