This part of IEC 62271 is applicable to a.c. circuit-breakers designed for indoor or outdoor installation and for operation at frequencies of 50 Hz and 60 Hz on systems having voltages above 1 000 V.<\/p>\n
\nNOTE While this technical report mainly addresses circuit-breakers, some clauses (e.g. Clause 5) apply to switchgear and controlgear.<\/p>\n<\/blockquote>\n
This technical report addresses utility, consultant and industrial engineers who specify and apply high-voltage circuit-breakers, circuit-breaker development engineers, engineers in testing stations, and engineers who participate in standardization. It is intended to provide background information concerning the facts and figures in the standards and provide a basis for specification for high-voltage circuit-breakers. Thus, its scope will cover the explanation, interpretation and application of IEC 62271-100 and IEC 62271-1 as well as related standards and technical reports with respect to high-voltage circuit-breakers.<\/p>\n
Rules for circuit-breakers with intentional non-simultaneity between the poles are covered by IEC 62271-302.<\/p>\n
This technical report does not cover circuit-breakers intended for use on motive power units of electrical traction equipment; these are covered by the IEC 60077 series.<\/p>\n
Generator circuit-breakers installed between generator and step-up transformer are not within the scope of this technical report.<\/p>\n
This technical report does not cover self-tripping circuit-breakers with mechanical tripping devices or devices which cannot be made inoperative.<\/p>\n
Disconnecting circuit-breakers are covered by IEC 62271-108.<\/p>\n
By-pass switches in parallel with line series capacitors and their protective equipment are not within the scope of this technical report. These are covered by IEC 62271-109 and IEC 60143-2.<\/p>\n
In addition, special applications (among others parallel switching, delayed current zero crossings) are treated in annexes to this document.<\/p>\n","protected":false},"excerpt":{"rendered":"
