Answer Posted / nirajan poudel
11000/440v means it is step-down transformer.so, for MV
side use 9kv LA,11 kvDO-FUSE and switch gear panel which
includes VCB which is used for isolating the transformer
during maintenance period.For LV side use TP MCCB for 3-
phase bus bar(R,Y,B) and use SP MCCB for 1-phase bus
bar.And there must be provision for AMF (Automatic Main
Failure Panel) to change the supply from main line to stand-
by generator and vice-versa with respective CB tripped.
