3-Phase magnatic field generates a balance rotation and
enough required torque aswellas it is economical to use 3-
Phase in genration and motoring purpose

Answer / raj

answer 4 is correct, for most efficient use we gone for 3
phase,

Answer / saikrishna

we can generate in 4 and 5 phase but 3 phase system is
balanced system and insulation cost also less in 3 phase
system.

Answer / raju

we get smooth non pulsating torque in 3 phase system...
n it is more economical to use 3 phase then 2,4,5 n more.

Answer / max

the practical reason the vibration machine less in 3 phase
but there is as such no rule to have 3 phase u can have as
many as phase u want but u gen must have that kind of windings
to generate 3 phase

Answer / palak shah 09879803533

since the waveform of current or voltage is sinosuidal so v
can only generate 3 phase. also if v use 4 phase the 180/4=
45 degree would be distributed and so motor will run for
sometime then stop for sometime and the again run for
sometime....... so ultimately windings will burnt.

HR- Q.1 Name,hobbies & About family background ? Q2.What u know abt NTPC ?? Q3.Why u want to choose NTPC as ur Carrier's starting i.e power sector not any other Oragnisation or sector ?? Techincal Questions- Q1.What is the reason for transformer Noise ?? Q2.Which material is used for making Transformer oil & How u measure its dielectric strength & Name the test ? Q.3 Which Machine u will prefer 2 use if flammble gases are coming out at a place & why ?? Q4.What is relation b/w Transmission Lines & Communication Lines ? Q5.What is the maximum capacity Synchronus Machine & total powerGeneration in our country ? Q.6 In india Power generation is at 50Hz while in America its 60 hz ,why so ?? Advantage or disadvantage ?? Q.7 Maximum Generation Voltage in india ? Q8. What is the Voltage regulation & why its required n how much is permissible ? & causes of voltage variation ?? Q.9 Why electric shock is feel ?? n in a Electric Train why we didnt feel that ?
