what is the difference between 3 phase and single phase transformer?

The primary difference between a three-phase and a single-phase transformer lies in their design and application. A single-phase transformer is used in residential and small commercial applications, handling one alternating current (AC) waveform. In contrast, a three-phase transformer is designed for industrial and large commercial use, managing three AC waveforms, which allows for more efficient power distribution and higher loads. This results in better voltage stability and reduced losses in three-phase systems.
