A transformer which offers neutral ,when the neutral is not
available, is called neutral Tr. It is just like a star
connected primary of a transformer of the rated voltage with
or without secondary.The star point can be used for earthing
as well as for using single phase appliances.

Answer / murugan.k

The Neutral transformer is mainly used to reduced return flow of earth fault current to the main transformer winding. It's just act as a resistive path in the Neutral side. Beacause when Earth fault occur in the high voltage line, A huge amount of current flow's through the neutral.

Answer / srikanth

to operate an equippment phase and neutral is necessary.
for phase u have to take where as for neutral by providing
neutral transformer we can use...(simply neutral t/f act as
return path). and use of t/f can be used for small range as
well as large range...

Answer / pappu gore

neutral transformer is used to derive a neutral-to-earth connection for systems that do not otherwise have one.

I have 4 busbar of 1000 ampere. we use 4 busbar to make 4000 ampere in one phase.my problem is that when we applied 60% load on that then busbar produced high noise.what is the reason of that and how can i minimize that noise.
