  • SF6: Insulated switchgear for DC voltages up to 600 kV

    Aug 01, 1982The development and testing of the main components of a metal clad SF6-insulated switch gear for dc voltages up to 600 kV are described. The technical requirements of the components were derived from the design of a switchgear arrangement. The switchgear was tested, proving that switching requirments were met. A metal clad measuring device for high dc voltages was developed.Author: V. Rees
