Answer / iamdon

The medium length transmission lines are analysed with the
help of two models...
1)Nominal pie model
2)Nominal T model.

Out of these two models,Nominal pie model is superior in
following terms..

1)In the case of Nominal T model, an extra node is
introduced at the T junction,which increases the order of
system by 1.Increase in order of a system is never desired
as it complicates the control analysis particularly.Nominal
pie model doesn't alter the order of system.
2)In case of Nominal pie model,all shunt parameters
appearing at load end and sending end can be respictively
added to get the equivalent.This simplify the calculation.

There is one 40MVA oil cooled transformer (yet to commission), filled with 95% oil and we are trying to fill 5% Nytrogen in that transformer so that there should not be any foreign component inside. But even though there is no leakage, nytrogen is not withstanding inside transformer, within a day or two pressure guage is showing 0. Why is it soooo? Pls reply.
