The Dielectric Strength of Cryogenic Fluids and Solid Insulators
A research and development program has been conducted since 1962 to develop new electrical machines using high-purity metals as conductors. This program is principally aimed at the development of high-rating and consequently high-voltage electrical machines. In support of this program it was decided to undertake high-voltage tests of cryogenic fluids and of solid insulators at cryogenic temperatures. The possibility of tests in liquid helium was also considered since the use of fastdischarge superconducting coils induces a high voltage in such equipment.
