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.

Why does the speed regulating system adopting I controller have no steady-state error? In this single closed-loop speed regulating system, when the input of the I controller Un=0, what is the output voltage of the regulator? What factors do the output voltage depend on?

I have connected 04nos. earthings to a transformer through 04nos. earthing pits seperately. 02nos. earthings are connected to T/F body, and 02nos. earthings are connected to T/F neutral.T/F capacity is 2000KVA, 11KV/415V. But after completing of 02 years successful operation ,we are facing following problems- 1. CT/PT occured blast one time 2. HT cable box occured blast two times 3. One body earthing strip and one neutral earthing strip of transformer are overlapping at some places. Whenever these two strips are pressed at overlapped points, they made spark. What is the reason of spark? Please explain the reason & rectification of above problems
