what is the difference between neutral and earth?
I want Primary side delta and Sec side Star connection transformer . but i have received Star - Star transformer ,shall i use the same transformer by giving the only 3 ph on Primary side without Neutral connection on the Starpoint.
why does in transformer the v/f ratio constant?
How will change the frequency in distribution side?
Can anyone tell me some hints about what type of questions are asked by the interviewer by an Electronics engineer when company is installing an IPP and wants a team of engineers?
which are the criterias needed to select the kind of neutral earthing(solid earthing,resistance earthing,etc.) at various voltage levels in electrical distribution?
Suppose am having the PF value .8, so how can we say that is it lagging or leading?
what is meant by transformer differential protection ?
why use delta star x-mer in distribution system.
What are electric motors?
How can we calculate the capacitance of generator?
What will the effect on a motor designed at 60 HZ, and operated on 50 HZ ??
