IEC 62271-111:2019 applies to all overhead, pad-mounted, dry vault and submersible single or multi-pole alternating current automatic circuit reclosers for rated maximum voltages above 1 000 V and up to and including 38 kV. Devices that require a dependent manual operation are not covered by this document. In order to simplify this document where possible, the term recloser (or reclosers) has…

IEC/IEEE 62271-37-013:2015(E) is applicable to three-phase a.c. high-voltage generator circuit-breakers, hereafter called generator circuit-breaker, designed for indoor or outdoor installation and for operation at frequencies of 50 Hz and 60 Hz on systems having voltages above 1 kV and up to 38 kV. It is applicable to generator circuit-breakers that are installed between the generator and the…

IEC/IEEE 62271-37-082:2012(E) provides methods for the measurement of sound pressure level produced by outdoor alternating current circuit-breakers in a free-field environment. These methods may also be used indoors or in restricted field, provided that precautions are observed in the measurement and interpretation of the results. This standard has been prepared by subcommittee 17A: High-voltage…

IEC 62271-111:2012(E) applies to all overhead, pad mounted, dry vault and submersible single or multi-pole alternating current automatic circuit reclosers and fault interrupters for rated maximum voltages above 1 000 V and up to 38 kV. This second edition cancels and replaces the first edition, published in 2005, and constitutes a technical revision. The main changes with respect to the previous…
