A Welder performance test

Applicable to cast aluminium alloy enclosures pressurized with dry air, inert gases, for example, sulphur hexafluoride, carbon tetrafluoride, or nitrogen or a mixtures of these gases, used in indoor or outdoor installations of high-voltage switchgear and control gear, where the gas is used principally for its dielectric and/or arc-quenching properties, with rated voltages: (a) 1 kV and up to and including 52 kV and with gas-filled compartments with design pressure greater than 3 bar (gauge); and (b) 72.5 kV and above. Also covers pressurized components such as the centre chamber of live tank switchgear, gas-insulated current transformers, etc.
