Answer / aamirali

Neutral voltage is zero, when the fault occours it becomes
equal to phase voltage.

Answer / guru

The Voltage Unbalance in the 3 phases create a floating
voltage which reflects in the neutral.( Sometime it will be
equal to phase voltage itself). That is why neutral in the
secondary side of the transformer is always grounded and it
is not connected to the main earthing grid. By Making a
seperate earthing for neutral avoids the unnecessary earth
fault tripping in the circuit

Answer / raj kushwaha

If star connection than Neutral voltage is zero in normal
circuit. But if unbalance load than Neutral currant can not
be zero.

i want to ask that as everybody knows that in star connection on star point is called neutral. my question is that why on that poin called neutral. what is the reason behind it. what is the logic behind it. i heared somewhere that on this point all phases current become zero thats why. if this answer is right then prove why on that point is current become zero. if this answer is not right then tell me the right answer. post ur answer here or on my mail address. m.ikram786@yahoo.com m.ikram555@gmail.com. thanks.
