A split phase system
A two phase system
There's no fancy picture here but I'll offer two simple quotes:
"Two-phase electrical power was an early 20th century polyphase alternating current electric power distribution system. Two circuits, or "phases", were used, with voltages 90 electrical degrees apart in time."
"Three-wire, 120/240 volt single phase power used in the USA and Canada is sometimes incorrectly called "two-phase". The proper term is split phase or 3-wire single-phase."
I see what you mean, you're telling us about a system used in 1895! - does this have any relevence in the 21st century?.
As for the American system being incorrectly called 'two phase', I would have thought it's a better, more sensible, name for it - and makes more sense than reserving the name for a long obselete system?. I'm presuming they don't still use that antiquated system for driving motors anywhere?.
