ABSTRACT
Windings form the most important part of a transformer, which is necessary to affect the required transfer of electric power from the primary or source side to the secondary or load side at maximum efficiency. These issues become more critical while designing transformers suitable for solar energy applications because of the sudden changes in various factors like voltage variations, harmonics, and frequency variation in general. Note the positions of the conductors, as these are wound on the former and the subsequent transpositions, thus ensuring equal length of the conductors for each layer of the helical or spiral winding, resulting in uniform resistance of the overall winding conductors. Forces between conductors of the primary and secondary windings of a transformer lead to radial and axial forces. The former cause the winding close to the core to compress radially and the winding on the outer diameter to expand radially.
