A theoretical investigation of transformer design . loss, copper loss, total loss, reactance and magnetizing current. The crossing point of the two loss curves is taken as the design condition desired. These two sets of curves, Fig. 12, 13, 14 were calculated for two i o voltages, 1100 and 3300 for theAK. V. A. and 1100 and 4400 for the 30 K. V. results show that the volts per turn are almost independent of the a 20 : 1 ratio, calculations were then made for four different valuesof volts per turn for each of five different capacities, viz., 10, 20, 30,40, and 50 K.

V. A. The results are given graphically in curves, Fig. 15,16, 17, 18, and 19. With the volts per turn for equal copper and iron lossesas taken from these curves, i. e., from the point of intersection of ironloss-curve and copper loss-curve, a curve was plotted between K. V. and volts per turn, see Fig. 20. The equation of this curve is theformula sought. The curve is a parabola represented by the following simple equation, V = VK. V. A. T. (I, CF I. C. *. rORM 3
