Abstract

991,790. Transformers. BRUSH ELECTRICAL ENGINEERING CO. Ltd. Nov. 15, 1962 [Nov. 15, 1961], No. 40807/61. Addition to 924,130. Heading H1T. An on load tap changing equipment in which the connection and disconnection of each tapping is effected by a vacuum switch or switches of a type employing solid contacts as in the parent Specification, has independently operable tap selectors X, Y connected to the non-tapped portion 21 of the two-part phase winding, one via one such vacuum switch A, and the other via two such switches B, C, switch B having a resistor 24 connected across it and being adapted to open momentarily when a tapping change is to be made. The inter-tap current is thus reduced by resistor 24 when the selectors X, Y contact adjacent tappings during tap-changing and is started by switch C when the change has been completed.
