Abstract

159,764. Hawkins, H., Hanstock, W. H., Higgs, A. H., and Ferranti, Ltd. March 11, 1920. Addition to 155,095. Cut-out arrangements.-A protective arrangement comprises transformers b situated at each end of a feeder a, the secondary windings of the transformers being connected to common points. Pilot wires d are connected to the common points and normally no current flows in these wires. When a fault occurs, relays e in the pilot wires are energized to close the circuits of the tripping- coils g of switches h. Overload relays c are connected in each phase of the transformer secondary.
