A 3-phase, 50 Hz, oil cooled core type transformer has the following dimensions: distance between core centres 0.4 m, height of window 0.48 m, dia of circumscribing circle 0.28 m. The flux density in the core is 3.00 Wb/m² and the current density in the conductors is 5.0 N/mm². Estimate the KVA rating. Assume a window space factor of 0.4 and a core area factor= 0.56 the core is 2 stepped.

Single Phase Transformer

A single-phase transformer is a type of power transformer. It is an electrical device that accepts converts the single phase alternating power into single phase alternating power. In this power conversion the voltage is stepped up or down. If the voltage is stepped up, the current will be stepped down and if the voltage is stepped down, the current will be stepped up.
