Which of the following can be operated at higher frequencies
?
-SCR
-MOSFET
-IGBT
Answer Posted / chandrika
mosfet can be operated at high frequency ,because in this
only majority carriers r there and no secondary breakdown
is not there.

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
