Abstract: 387,476. Rectifying alternating currents ; protective systems. KING, A. J., 46, Raglan Road, Stretford, Manchester, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Crown House, Aldwych, London. Dec. 21, 1931, No. 35341. [Class 38 (ii).] An arrangement for rendering available a supply of direct current in a polyphase system, for protective or other purposes, comprises transformers in each phase, the secondary windings of the transformers being connected in series with the primary windings of auxiliary transformers, whose secondaries are connected to rectifiers having their direct current circuits connected in parallel. In the arrangement shown, for supplying direct current for consumption in apparatus employed in protecting a three-phase system against interphase and earth faults, current transformers 2a, 2b, 2c in each phase are connected through voltage transformers 3a, 3b, 3c and rectifiers 5a, 5b, 5c to the direct current lines 6. An additional current transformer 8, responsive to earth currents, is also connected to the lines 6 through a voltage transformer 9 and rectifier 11, the transformation ratio of the transformer 8 being such as to render direct current available for an earth current smaller than the current required to give the same direct current voltage on phase faults. The direct current may be used for supplying anode potential to electric discharge tubes used in the protective arrangements, the current transformers supplying other parts of the apparatus with alternating currents representative of the line and earth currents through leads 4a, 4b, 4c, 10. The rectifiers may be of the dry-plate type. A modified arrangement is described for use with protective arrangements in which the secondary windings of the current transformers 2a, 2b, 2c are connected in star.
