Why 2 phase induction motors are not used in industries?
A two-phase* system is archaic, and has been completely superceded by three-phase systems, so there is no demand for two-phase induction motors. (*A two-phase generator has two phase windings, displaced from each other by 90 degrees.)
In a 480 Volt 3-phase power supply what is the voltage between each lead?
Assuming this is a WYE connected system: (Most commercial/industrial services are) Your question answered it: 480 volts. The phase to phase voltage on this system is 480 volts and the phase to ground voltage is 277 volts.AnswerThe 'leads' you refer to are more-properly called 'lines', and the voltage between any pair is called a 'line voltage' (not a 'phase voltage', as stated in the original answer). The rated voltages of three-phase systems, regardless of whether they are three-wire (delta) systems or four-wire (star/wye) systems are always quoted in terms of their 'line voltages'. So, to answer your question, the line voltage ('voltage between leads' ) of your three-phase system is 480 V. If your system is a four-wire star/wye system, then the phase voltage voltage, or 'line-to-neutral' (not 'phase to ground') voltage is the line voltage divided by 1.732, i.e. 277 V.
You have 230v 3 phase power can you plug a 230v single phase motor into it?
Any two legs of a three phase system are classed as single phase. So yes a single phase motor will operate when connected. Be sure to use the proper motor protection devices to control the motor.
How does 3 wire and 4 wire system differs?
If you are referring to a.c. three-phase systems, then a three-wire system is associated with a delta-connected system, while a four-wire system is associated with a star, or wye, system. The conductors being three line conductors and a neutral conductor.
What is a balanced three phase system?
A balanced three phase system is where the currents into the loads placed on all three phases of the service are reasonably close to each other in amperage.Another opinionA 'balanced' three-phase system describes a three-phase load in which each phase current is identical in both magnitude and phase. If the phase currents are only 'reasonably close', then the load is not balanced.
What does phase II of management information systems development entail?
Phase II identifies the requirements for the systems. It includes systems analysis, user requirements, necessary hardware and software, and a conceptional design for the system.
What does phase III of management information systems development entail?
Phase II identifies the requirements for the systems. It includes systems analysis, user requirements, necessary hardware and software, and a conceptional design for the system.
What is the main purpose of the preliminary investigation activity conducted during the analysis phase of the system development cycle?
It helps in product life cycle
What does phase IV of management information systems development entail?
Phase IV is the implementation of the system. The new system is converted from the old system, and the new system is implemented and then refined. There must then be ongoing maintenance and reevaluation
Why 3 phase ac systems is preferred to 4 phase?
3 phase system has more power than a single phase system
1 Where does systems implementation fit in the SDLC what tasks typically are performed during systems implementation and why is quality assurance so important?
1- System Implementation is fourth of five phases in the systems development life cycle (SDLC). In the systems design phase we developed a physical model that include data design, user interface, input and output design, and system architecture , Now we are in the system implementation task which includes application development, testing, documentation, training, data conversion, system changeover, and post-implementation evaluation of the results. At the conclusion of the system implementation phase users will be working with the system on a day-to-day basis, and will focus on system operation, security, and support which is the final phase in the SDLC. 1- System Implementation is fourth of five phases in the systems development life cycle (SDLC).

How can successful and through systems planning analysis and design the ruined by poor system construction and implementation?
a system development life cycle consists of analysis,design,construction,testing and implementation.When a system is to be designed it needs a proper analysis or you can say proper investigation which includes requirements,use and future scope of a system.An analysis is the starting phase for a system which will be designed.Even a successful and through systems planning analysis and design can be ruined if a poor system is constructed as this phase consist of coding & logics and if the coding and logic and coding are not correct the implementation will also effect.That is the reason a proper check should be made in construction phase that the analysed data is up to the mark.
What does phase I of management information systems development entail?
Phase I is systems planning. The systems team must investigate the initial problem by determining what the problem is and developing a feasibility study for management to review.
What are the advantages of three phase to two phase electric power distribution systems?
Polyphase systems are used because they allow the efficient transmission of electric power, in terms of power transmitted per kilogram of wire. Polyphase systems with more than three phases are very uncommon.
The program development cycle begins at the start of the planning phase in the system development cycle?
No, that is false.
During which phase of the system development life cycle does the actual programming occur?
development and documentation
Does the program development cycle begin at the start of the planning phase in the system development cycle?
False.
