Description of BS EN 50089:2022 2022

This document applies to pressurized partitions used in indoor and outdoor installations of high-voltage AC and DC switchgear and controlgear with rated voltages (Ur) above 1 kV AC / 1,5 kV DC and with design pressure higher than 300 kPa, where the gas is used principally for its dielectric and/or arc-quenching properties. The partitions comprise pressurized barriers in electrical equipment not necessarily limited to the following examples: - circuit-breakers; - switch-disconnectors; - disconnectors; - earthing switches; - current transformers; - voltage transformers; - surge arresters; - busbars and connections; - cable connections/terminations; - cable bushings. Partitions which are only pressurized from one side are also covered. 1 kV AC / 1,5 kV DC means it is valid for the apparatus applied and where the partitions are installed; however, the application of voltages below 1 kV AC / 1,5 kV DC as in, for example, current and voltage transformers are not excluded. This document does not apply to high voltage bushings (see EN 60137, EN 61462 and EN 62155).
