1892 T. O'C. Sloane Standard Electr. Dict. (1893) 251 Ferranti effect, an effect as yet not definitely explained, observed in the mains of the Deptford, Eng., alternating current plant.
1893 M. H. Kilgour et al. Electr. Distrib. xi. 387 The Ferranti mains are made with a very large margin of safety.
1902 Encycl. Brit. XXXIII. 424 The Ferranti rectifier is much employed for rectifying alternating current for arc lighting purposes.
1940 Chambers's Techn. Dict. 328/1 Ferranti effect, the rise in voltage which takes place at the end of a long transmission line when the load is thrown off.
1942 J. W. Meares & R. E. Neale Electr. Engin. Pract. (ed. 5) II. xvii. 94 The Ferranti rectifier consists of a synchronous motor driving a commutator, alternate segments of which are connected to slip rings on the same shaft.
1946 P. J. Selgin Electr. Transmission v. 107 Any value higher than this will result in the Ferranti effect, the line acting in this respect as a step-up transformer.
