    Abstract - (Show below) - (Hide below)

    Applies to gas-insulated metal-enclosed switchgear in which the insulation is obtained, at least partly, by an insulating gas other than air at atmospheric pressure for alternating current of rated voltages of 72.5 kV and above, for indoor and outdoor installation, and for service frequencies up to and including 60 Hz. This Standard is identical with and has been reproduced from IEC 517:1990, including Amendment 1:1994.

    Scope - (Show below) - (Hide below)

    This standard specifies requirementsfor gas-insulated metal-enclosedswitchgear in which the insulation is obtained, at least partly, by an insulating gas other than air at atmospheric pressure, for alternating current of rated voltages of 72,5 kV and above, for indoor and outdoor installation, and for service frequencies up to and including 60 Hz. For the purpose of this standard the term "switchgear" is used for "gas-insulated metal-enclosed switchgear". The gas-insulated metal-enclosed switchgear covered by this standard consists of individual components intended to be directly connected together and able to operate only in this manner.This standard completes and amends, if necessary, the various relevant standards applying to the individual components constituting gas-insulated metal-enclosed switchgear. Unless otherwise specified, the gas-insulated metal-enclosed switchgear is designed to be used under normal service conditions.
