Electrical Myths - Single phase is Really 2-Phase - Short #157
In this short podcast, Bryan busts the common electrical myth that single-phase 240v power is really two-phase power.
When power goes into a structure that runs 240v appliances, we may understand that two 120v sine waves are 180 degrees out of phase with each other, but that isn't 100% accurate. If we were to use an oscilloscope to watch the electrical sine waves, we would see two sine waves 180 degrees out of phase because the transformers are center-tapped. Center-tapping creates a neutral center point that becomes our reference.
The transformer has two sides: a primary and a secondary. The…
