BS EN 50187:2022

This standard BS EN 50187:2022 High-voltage switchgear and controlgear. Gas-filled compartments of AC switchgear and controlgear with rated voltages above 1 kV up to and including 52 kV is classified in these ICS categories:

• 29.130.99 Other switchgear and controlgear
• 29.130.10 High voltage switchgear and controlgear

This document applies to pressurized gas-filled compartments of AC switchgear and controlgear with rated voltages above 1 kV and up to and including 52 kV for indoor or outdoor installations, where the gas or gas mixture is being used principally for its dielectric and/or arc-quenching properties and where the gases or gas mixtures in the compartment can be considered in conditions being chemically stable over its lifetime and non-corrosive to the material of the pressurized compartment in the conditions that prevail inside.
