What is the use of the laminated and transposed conductors in turbo alternators?(a) to decrease the harmonics(b) to decrease the heating effects(c) to decrease the iron and core loss(d) to decrease the eddy current lossThis question was addressed to me in an interview for job.Origin of the question is Construction of Turbo-Alternators topic in chapter Design of Synchronous Machines of Design of Electrical Machines

Answer»

Correct answer is (d) to decrease the eddy current loss

To explain I would SAY: The presence of LARGE CURRENTS requires the use of multi circuit WINDINGS. The use of the laminated and transposed conductors in TURBO alternators is to reduce the eddy current loss.
