[The name of Charles F. Scott (1864–1944), U.S. electrical engineer, who devised the connection in 1894 (Electrician 6 Apr. 640).]
Scott connection: a way of connecting two single-phase transformers to convert a three-phase voltage to a two-phase one (or to two single-phase ones), or vice versa: on the three-phase side the mid-point of the main transformer is connected to one terminal of the second transformer; the remaining three terminals form the terminals for the three-phase supply; the two-phase supply is taken from the two pairs of terminals on the other side. So Scott-connected adj.

Alternating Currents ix. 200 The so-called ‘Scott’ connection is an arrangement of two single-phase transformers, whereby three-phase power may be obtained from a two-phase circuit or vice versa. 1935Monseth & Robinson Relay Systems x. 304 (caption) Scott-connected transformer differential protective scheme. 1947R. Lee Electronic Transformers & Circuits viii. 214 When autotransformers are used on three-phase supply lines, they may be connected the same as two-winding transformers in star, delta, open-delta, or Scott connections. 1966Brosan & Hayden Adv. Electr. Power & Machines vi. 243 The Leblanc system was invented about five years after the Scott connexion when the latter had obtained a firm foothold in Britain and its use was therefore confined to the Continent.
