Answer Posted / harsh zala
We can use transistor as a switching device but only for
low voltage application(for e.g electronic ckt)
If we want to use it in an electrical ckt, then we have to
go for higher current capacity, which are available upto
certain extent, but other switching devices are far more
cheper and responds good compare to it.
As we know it is current controlled device, so if we apply
large voltage diffrance or higher base current it can falsy
trigger, that is not desirable.

What is the need of earthing transformer for delta side of a transformer. (Think of a line section between a star/delta transformer at a grid substation and delta/star transformer at a village. An earthing transformer is there at the delta side of the star/delta transformer at grid substation). As there are no ground reference there will not be fault current if a one phase is grounded. Further L-L phase will be sensed by the primary side of star/delta transformer as a L-G fault. So why an earthing transformer is required at delta side
