Answer / ravi

To keep the neutral stable in case of unbalanced loads, to
nullify the 3rd harmonic currents in the windings by
carrying to them to ground

Answer / sinod kumar

to provide a path for odd harmonics(mainly 3rd &
5th)component of magnetizing current to get sinusoidal flux
and undistorted emf.

Answer / kartikesh

To provide a path to ground to winding harmonic rrent
generated due to unbalanced load ,to nulified the 3rd
hamonic current it should be grounded

Answer / ajit

To stabilise the neutral current .To minimise the earth
fault current.For harmonic supression.

We have two Al.busbars each of size 125mm*10 mm connected in parallel.To increase the current rating ,can we connect third busbar of size 100mm*10mm in parallel to existing two busbars?In my opinion ,if we connect busbars of different sizes in parallel,then the busbar of lowest size will take much current.So this type of paralleling should be avoided .Am I correct?
