Answer / chirag patel
Earthing is connecting non-current carrying parts of equipments to ground in order to avoid electric shocks.It may be also used for protection by measuring leakage current
While Neutral is connecting R ,Y ,B Phase to common point with ground it is called system earthing

Answer / sudhir
neutral
1)neutral works as return phath for completing the circuit
2)it protects the equipment by surge volage(by fault) not human
3)neutral wire may be earthed or not
earthing
1)it also uses as return phath for completing the circuit
2)it protects the equipment by surge volage(by lightning)
and it also protect human.
3)it should be earthed.
earhing can works as neutral but neutral can not works as
earthing

Answer / praful nandankar
Neutral is a point where all the three phases are
connected.Earthing is used for the safety purposes.Neutral
point is necessary to eliminate the third harmonic current
in case of synchronous generators.If some equipment is
earthed it means even if some eletric stresses are
produced,the overvoltage is directly discharged to groun.At
neutral,IR+IY+IB=0.

Answer / rajasekhar
earthing is used for protection purp[ose we can use neutral
as ground bnut can't use ground as neutra;l

Answer / abhishek-gaur
EARTHING: for protection... works during fault
NEUTRAL: part of circuit until circuit is off
and,,, earth can b used as neutral (as in SWITCH WIRE EARTH

Dear sir, I am working in wind mill division , pls explain Pls explain in details with formula My question is Wind speed 3.5 M/s Gen RPM is 1500 ( 25 K/w Production ) Wind speed 12 M/s Gen RPM is 1500 ( 220 K/w Production ) Why in 3.5 m/s generation was low , why in 12 m/s generation was high , Pls dont explain wind force or wind density , that one already i know For the above question RPM was same why the KW was different Answer : 1. Its depends on the density ( Force ) of the air Sir , Pls explain wit Formula sir
