High-voltage oil circuit breaker tests, Alabama power company system

IN conjunction with the Alabama Power Company, a series of 50 high-voltage oil circuit breaker tests was made during May and June of 1922. The Bessemer substation of the power company was chosen as the location for these tests due to the large power concentrations that were possible on short circuit, the possibility of maintaining system voltage under short circuit to the greatest extent and because it was felt that less interruption to service would occur if tests were made here than elsewhere.
