IEEE C37.11-2022 PDF
This standard establishes basic requirements for the control schemes of electrically controlled ac high-voltage circuit breakers rated above 1000 V. This standard is applicable to any type of power-operated mechanism and for both ac and dc control power. Only the basic control elements of the circuit breaker, including reclosing where required, are included in this standard. This standard does not include devices or circuits for protective relaying, special interlocking, and so forth, since these are external to and dependent upon the specific application of a particular circuit breaker.
The purpose of this standard is to establish basic requirements for ac high-voltage power circuit breaker control schemes so that users and manufacturers can help effect engineering and production economies by reducing the multiplicity of special control schemes that are specified in the absence of standards.
Revision Standard – Active. Standard requirements for all types of electrical control circuits for ac high-voltage circuit breakers rated above 1000 V are given. Any type of power-operated mechanism and both ac and dc control power are applicable for this standard. Only basic control elements of the circuit breaker, including reclosing where required, are included in this standard. Devices or circuits for protective relaying, special interlocking, and so forth are not included.
