AS 62271.201:2019 PDF

The objective of this Standard is to specify requirements for prefabricated solid-insulation enclosed switchgear and controlgear for the following: (a) Alternating current of rated voltages above 1 kV and up to and including 52 kV for indoor installation. (b) Service frequencies up to and including 60 Hz.

This Standard supplements the Standards for the individual components regarding their installation in switchgear and controlgear assemblies.

This Standard does not preclude that other equipment may be included in the same enclosure. In such a case, any possible influence of that equipment on the switchgear and controlgear should be taken into account.

This Standard is an adoption with national modifications, and has been reproduced from, IEC 62271-201:2014, High-voltage switchgear and controlgear — Part 201: AC solid-insulation enclosed switchgear and controlgear for rated voltages above 1 kV and up to and including 52 kV. The modifications are additional requirements and are set out in Appendix ZZ, which has been added at the end of the source text.
