Basically starter is used for purpose of limiting the starting current ther by it protect the equipment ( motor and generator)from high current , thus the windings of equipment are protected.
If no starter is used then the starting current will be huge which damage winding.
I.e v=ir,
I= v/r
I=220/0.2
I=1100Amp. which is dangerously high
Where as in case of transformer to protect it from high inrush currents the windings are mechanically braced to with stand these forces.
That's way no starter is used.
AND
Starter is used where breaking and starting operations occurred mostly.
But if once we start the transformer we can't break it until any abnormal condition occurred.

Hello everyone, somebody knows what is a "surplice power" ? The hole phrase is: "This rating is appropriate for a generator set paralleled with an infinite bus e.g. a national electrical supply network or grid where the generator set is run at 100% load, 24 hours a day, 365 days a year and any surplice power is exported into the grid" Thanks in advance.
