|why ac generator ratings in kva only why not kw ?????????????
|why we used servo motor insted of inducation motor?
|there is a power transformer 66/11kV in delta-delta
connection has 5 feeder coming out from the secondary side.

or delta-delta ?
|Can neutral line also be use as a earthting for
distribution transformer, or we need separate earthing pit
forh the transformer?
|How can we calculate the resistance of earthing & how can we
