Single Phase, 3 Phase, and Split Phase Explained
In this podcast episode, we discuss power distribution and some practical tips about three-phase, single-phase, and split-phase power.
The power company generates three-phase power; a power pole transformer typically has three current-carrying conductors. Each phase of power runs at 60 Hz and generates a sine wave. That sine wave peaks and valleys in a wavy formation. Power is generated in a rotating magnetic field, so it is helpful to think of a sine wave as a variation of a circle.
Transformers take high voltage and bring it down to 120V split-phase via a winding on the left, a winding on…
