The theory could be this: If you had 40 questions in the morning session and 40 questions in the afternoon session, for each correct answer in the morning you will receive one point. For each correct answer in the afternoon you will receive one point. Thus the maximum possible total of points...

0.025 is the pu fault duty impedance of 40MVA on 12.47KV system Zsystem(pu) =1MVA(base)/(40MVA) = 0.025 If you take 40 MVA Base then: Zsystem= 1pu on 40 MVA base ZTransformer= ZT= 0.04*(40/1)= 1.6pu on 40 MVA base = > Isc=1/(1+1.6) = 0.385 pu on 40 MVA base...

Dot Convention It is common in transformer schematic symbols for there to be a dot at the end of each coil within a transformer, particularly for transformers with multiple windings on either or both of the primary and secondary sides. The purpose of the dots is to indicate the direction of...
