well things are explained well above.
i wud like to add something
WHAT WILL BE EFFECT WHEN PHASE DISPLACEMENT CHANGES IN
TRANSFORMER ?
Ans:-First thing under an abnormal condition(during fault)
the neutral point of trafo rised above the ground potential
and attains a positive potential,hence a current will flow
through the trafo neutral to the ground (mostly the trafo
neutral is earthed with or without a NGR.
As a whole the bottom line is trafo neutral will rise to a
potential which is not desired,protection against the same
is designed,which cut of the supply it this condition
prevails for a longer time( this time is descided at the
time of designing the system.

why use phase displacement in transformer.and effect of phase displacement on transformer
A 400 V, 50 Hz, Δ connected synchronous generator has a field reactance of 0.1 Ω and armature resistance of 0.015 Ω. At full load, the machine supplies 1200 A at 0.8 pf lagging. Under full-load conditions, the friction and windage losses are 40 KW and the core losses are 30 KW. What is the machine’s overall efficiency? Ignore any field circuit losses.
