Sebastian Ziani de Ferranti

Died 13 Jan 1930 at age 65 (born 9 Apr 1864).English electrical engineer who promoted the installation of large electrical generating stations and alternating current distribution networks in England. He was interested in electrical and mechanical devices as a youth, and in 1881, began such employment while in his late teens. In his 20's, he began planning an ambitious generating station about 8 miles outside London, to use transmission at an unprecedented 10,000 volts - four times greater than previously practical. For this he began designing suitable cables, transformers and generators. His idea of making high voltage flexible cables using wax-impregnated paper for insulation was a landmark development used exclusively until the advent of synthetic materials. His 176 patents cover varied inventions.
