why neutral grounding transformer is used for generator and why it is not used for transformers?..

Answer / tanvir s.

As far as i understand Neutral Grounding Transformer are used to Ground the both transformers as well as Generators. NGT is applicable (useful) in transformers/generators with delta connection. So during line-to-earth faults, the NGT helps the zero sequence current to flow in the ground. Any unbalance in the load distribution between the three phases is passed thru the neutral, which is not available in case of delta connection. Hence the NGT.
