Abstract
820,642. Protective arrangements. ALLMANNA SVENSKA ELEKTRISKA A.B. Sept. 3, 1956 [Sept. 16, 1955], No. 26815/56. Class 38 (5). [Also in Group XXXV] Current transformers 3, 4, 13, 14 feeding an indicating relay 16 in dependence on the single - phase current taken by a load 2, are controlled by D.C. saturation from a potentiometer 10, and are bridgeconnected to prevent feeding alternating current back into the D.C. source. Transformers 3, 14 and 4, 13 may consist of separate secondary windings on single cores.
