A two-phase system is an archaic 'polyphase' system, in which two phase voltages are displaced by 90 electrical degrees, enabling the use of self-starting induction motors. It's unlikely you'll come across a two-phase system these days.

What are the applications of three phase to single phase electric power distribution systems?
All high-voltage distribution systems are three-phase. Single-phase 'spurs' off the main line, supplying, for example, farm houses, are simply two lines of a three-phase system.
Why do you use three phase in AC systems?
It is more efficient and cheaper for some applications, such as higher motor loads.
When in the VMware Journey are business critical applications typically virtualized?
phase 2
What are the applications of automatic phase changer?
motor applications
What are the examples of oparating systems in the application software?
Operating systems are not in applications. Applications are installed on Operating Systems.

Can Microwave systems be long-haul applications?
Microwave systems can be categorized as long-haul applications
Can Microwave systems be short-haul applications?
Microwave systems can be categorized as short-haul applications
Why are motor windings single phase or 3 phase and not 2 phase?
rotating field which is necessary for rotation of rotor not produce with 2 phase .AnswerIn fact, a two-phase supply does supply a naturally-rotating field -which is one of the reasons why it was developed. However, two-phase systems are archaic and it's unlikely many individuals will ever come across one as they have been completely replaced by three-phase systems. So, I'm afraid the choice is between single phase or three phase -end of story!
When connecting a external generator 3 phase to an existing 3 phase electrical network how do you know that the 2 systems are in phase?
use a rotor phaser or simply connect a 3 phase motor and check dirrection
