Abstract

611,977. Protective arrangements; inductances. HANSELL, J. B., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. May 16, 1946, No. 14819. [Classes 38 (ii) and 38 (iv)] A reactor for earthing the neutral N of a polyphase system comprises a core 3, preferably having air gaps 4, on which is wound (1) a primary winding 1 for direct connection in the earth lead and (2) the main portion 2 of a secondary winding. The magnetic circuit of the core includes two or more parallel limbs 6A-6C, one of which is gapped and which carries a plurality of auxiliary portions 7-11 of the secondary winding. The last may be connected separately, or otherwise, across the main secondary portion by switches a-e to vary the effective reactance in the earth lead. The switching system may also permit seriesparallel connection of the auxiliary portions. Specification 392,942 is referred to.
