What is a Single Phase Transformer?

Single Phase Transformer Definition

A single phase transformer is defined as a device that operates on single-phase power to transfer electrical energy between circuits via electromagnetic induction.

Working Principle

The AC voltage source injects current into the primary winding, creating an alternating magnetic field that induces voltage in the secondary winding.

Components

Main parts include a magnetic iron core and copper windings, with essential insulation to prevent electrical faults.

Efficiency

These transformers are highly efficient with low losses due to the absence of mechanical friction. 

Applications

Commonly used in low voltage applications to step down voltage for electronic devices and convert AC to DC voltage.
