What is BS EN 62271-207 - Gas insulated switchgear seismic qualifications about?
BS EN 62271-207 is a British standard that is a part of the IEC 62271 series that applies to gas-insulated switchgear assemblies for alternating current of rated voltages above 52 kV for indoor and outdoor installations, including their supporting structure.
Guidance on interactions between the supporting structure and the soil/foundations is provided in Annex B. The seismic qualification of the switchgear assemblies takes into account testing of typical switchgear assemblies combined with methods of analysis. Mutual interaction between directly mounted auxiliary and control equipment and switchgear assemblies is covered. The seismic qualification of switchgear assemblies is only performed upon request.
Who is BS EN 62271-207 - Gas insulated switchgear seismic qualifications for?
BS EN 62271-207 on gas insulated switchgear seismic qualifications is useful for:
- The electrical industry
- The oil and gas industry
- Electrical equipment manufacturers and suppliers
- The mechanical industry
- Testing and inspection officers
Why should you use BS EN 62271-207 - Gas insulated switchgear seismic qualifications?
The seismic qualification shall demonstrate the ability of the switchgear assemblies to withstand seismic stress. It may be proofed by test or by a combination of test and analysis. During and/or after a seismic event, the seismic qualification must ensure that the equipment maintains its capability to execute the appropriate safety functions while remaining in a state that corresponds to the end of its certified life. The switchgear's size is considerably reduced due to the usage of SF6 (sodium hexafluoride) insulation and is typically utilized in applications involving medium and high voltage.
BS EN 62271-207 provides you with guidelines for the qualifications for gas-insulated switchgear that are significantly more appealing, including excellent reliability, less space, and reduced maintenance. Using BS EN 62271-207 guidelines helps in qualification approval, earthquake resistant design, maintaining safety and protection, and enhancing electric insulation and performance for longer service life.
