Question
Calculate the kVA output of a single phase transformer from the following data :
$$\frac{\text{Core height}}{\text{Distance between core centres}} = 2.8$$
$$\frac{\text{Diameter of circumscribing circle}}{\text{Distance between core centres}} = 0.56$$
$$\frac{\text{Net iron area}}{\text{Area of circumscribing circle}} = 0.7$$
Current density = $2.3 \text{ A/mm}^2$, frequency = $50 \text{ Hz}$, window space factor = $0.27$, flux density of core = $1.2 \text{ Wb/m}^2$, distance between core centres = $0.4 \text{ m}$.
