In hollow conductor the wall (outer surface)becomes thicker
for the same sectional area ,thus offering less
resistance.In case of stranded conductor ,the strands in
alternating positions share equal currents

In a Dyn11 transformer, how are the 3 windings of the delta connected? Assume that R1-R2, Y1-Y2, B1-B2 are the 3 windings on the HV side.

( Re: WHAT SHOULD BE THE RATING OF MCCB FOR 415V,3Ph,50KVAR CAPACITOR BANK Answer # 1 The capacitor current would be kvar x 1000 / (415 x sqrt3). This would be 70a approx. The MCCB selected should have *atleast 1.4 times this current i.e. 1.4 x 70= 98. So you should choose at least 100 A mccb.) regarding to this answer,i would like to know why the current have to times 1.4 to get the right amphere for the mccb.hows the formula to get the 1.4??tq
