Abstract
263,952. Taylor, A. M. July 11, 1925. Addition to 232,275. Drawings to Specfication. Transmission conductor arrangements.- In a transmission system according to the parent Specification employing intersheath cables and an overhead line in conjunction, the voltage of the latter is raised considerably above that of the principal core in the cable by using transformers. The overhead line may transmit load currents as well as the charging current for the core and intersheaths and overhead 'and underground systems may run parallel so that each may act as a standby to the other. The engaging currents of inductive loads concentrated at the principal substations are employed to furnish the energy for cable charging over such lengths of cable as will give resonance with the full load of the substation. An extra-high tension overhead line 220,000 volts three phase may be connected at intervals with underground 150,000 volt three-phase mains by small transformers in " dummy " substations arranged to step up or down the voltage of the charging currents for the principal cores and also to supply currents at appropriate voltages to the intersheaths. At the main substations the stepdown transformers perform similar functions. Inductances may be used in series with the secondaries connected to the intersheaths.
