Abstract
526,976. Electricity supply. BRITISH THOMSON-HOUSTON CO., Ltd. March 30, 1939, No. 9980. Convention date, March 31, 1938. [Class 38 (iv)] Transformer arrangements. - Short circuit currents in central stations are limited by using between bus bar and network transformers 6 having two or more primary windings 7. Each primary is supplied from a separate bus section and switches 3 interconnecting sections associated with any one transformer are opened on short circuit. The transformer windings 7 may be regulable.
