Question
Calculate approximate overall dimensions for a 200kVA,6600/440V, 50Hz 3 phase core type transformer. The following data may be assumed. Emf per turn = 10V; Maximum flux density = 1.3 Wb/m^2; current density = 2.5 A/mm^2; Window space factor = 0.3 overall height = overall width; stacking factor = 0.9. Use a 3 stepped core for a three stepped core. Width of largest stamping = 0.9 d and Net iron area = 0.6 d^2 where d is the diameter of circumscribing circle.
