W.E. Schwabe and B. Bowman introduced a conception of reactance factor when arc furnace is under operation.H. Noda and I. Eguchi also reported the variation of reactance, input power and power factor while arc furnace is in operation at the VIIIth U.I.E. Congress.After that we developed digitalized measurement device after making more accurate quantitative analysis about the above written electrical characteristic value.The results obtained are as follows:(1) About reactance value there is no big difference between the factor obtained by mean electrical value and that obtained by effective value.(2) Reactance factor can be universally expressed regardless characteristic values of arc furnace, voltage tap position of transformer and so forth by application of normalized current (I/Is) obtained after dividing short circuit current (Is) by undergiven respective voltage.(3) Accordingly, electrical characteristics at operation time can be obtained by understanding of short circuit impedance, voltage tap of transformer of arc furnace circuit and thus design and control can effectively be utilized.
