Basically transformer tests are of two types.
1)short ckttest 2)open ckt test
short ckt test gives us 1)copper losses 2)voltage regulation
3)lekage impedances(ie. resistance and lekage reactance )
open ckt test gives us 1)core losses 2)parallel component
values (ie Rc and Xm)3)secondary voltsge
Open ckt test will be done on lv side ,while short ckt test
will be on high voltage side

1) Explain why we don't link the two earthing system ht and mv on a pole mounted transformer sub-station.
Assuming that a dedicated neutral earthing transformer is provided for each GT generator, when the two generators are running in parallel, has consideration been given that the earth fault current from one generator stator winding be split between the two neutral earthing transformers? If so, what adverse impact will this have on the operation of the 59N and 27TN devices?
