The primary and secondary of a single-phase transformer carry 500 and 100 turns, respectively. The mean length of the flux in the core is 200 cm and the joints are equivalent to an air gap of 0.1 mm. If the maximum value of flux density is to be 1.1 Wb/m² when a potential difference of 2200 volt at 50 cps is applied the primary, calculate (1) the cross-sectional are of the core (11) the secondary voltage on no-load (ii) the primary current and power factor on no-load. Assume that 400 AT/m are required to produce a flux density of 1.1 Wb/m² and the corresponding iron loss to be 0.8 watt/kg at 50 Hz and the density of the iron to be 7.8 gm/cm³
Three-Phase Transformers
Three-segment transformers are a type of transformer used to transform voltages of electrical systems into three ranges. Two type transformers are shell-type transformer and core type transformer. In brief, it could be described because of the exquisite kinds of configurations.
Transformer
Ever since electricity has been created, people have started using it in its entirety. We see many types of Transformers in the neighborhoods. Some are smaller in size and some are very large. They are used according to their requirements. Many of us have seen the electrical transformer but they do not know what work they are engaged in.
