Starting currents of transformers : with special reference to transformers with silicon steel cores . Fig 3 8. The Oscillograms.—Out of a total number of eleven oscillo-grams taken, four are here reproduced, as follows:Oscil. 7. Circuit closed at o° point of e. m. f. magnetism, rush of current = 9.

Maximum rush of current, 4. Circuit closed at o° point of e. m. f. magnetism, rush of current = positive residual magnetism is meant that the magnetism was in thesame direction in which the flux would increase upon closing thecircuit. II. (6) Theoretical Calculations from Transformer Data. 9. Magnetization Curves and Hysteresis Loop.—These were ob-tained in the following way. The transformer was connected as shownin Fig. 4. Direct current from a storage battery was supplied the high
