A 3-phase, 50 Hz, oil cooled core type transformer has the following dimensions: distance between core centres 0.4 m, height of window 0.26 m, dia of circumscribing circle 0.14 m. The flux density in the core is 1.30 Wh/m^2 and the current density in the conductors is 2.5 A/mm^2. Estimate the kVA rating. Assume a window space factor of 0.2 and a core area factor = 0.56 the core is 2 stepped.
