Answer Posted / pugezhenthi.p
In transformer we provide the path [steel] for the
electromagnetic flux. So there is no interaction b/w the
flux. But in Induction Motor there is no separate path for
the magnetic flux. All the three phase fluxes are spread out
to the air gap, at the time only interaction b/w the flues
are possible. The interaction gives total resultant flux,
which is constant magnitude throughout the whole cycle, but
the axis of resultant flux is changes with respect to the
whole cycle. So we call this one as a Rotating Magnetic
Field[RMF].

My question is whether bellow formula is correct to find bus size for 46kA for 0.5 second & what is RT in bellow formula. formula to calculate the size of busbar to withstand the thermal stresses due to currents with duration of 0.2 sec to 5 sec. Sp = RT( I x I x t) / K Where Sp – is the cross sectional area of bus bar in millimeters. I - is the value of AC fault current. t - is the operating time of disconnecting device in seconds. K – is the factor depending on the material of the conductor, insulation and initial and final temperature. Value of ‘k’ for copper is 143.
