IEEE 1277:2020 pdf download.IEEE Standard General Requirements and Test Code for Dry-Type and Oil-lmmersed Smoothing Reactors and for Dry-Type Converter Reactors for DC Power Transmission.
The scope of IEEE 1277 is the definition and specification of the functional requirements and test code for dry-type and oil-immersed smoothing reactors and dry-type converter reactors for high-voltage direct current (HVDC) power transmission. This standard only applies to smoothing reactors for dc transmission and converter reactors for dc transmission located at the converter arms.
1.2 Purpose
The purpose of this standard is to provide those in the IIVDC industry, manufacturers, and “end users” a document that defines and specifies the electrical, mechanical, and physical requirements of dry-type and oil-immersed smoothing reactors for HVDC applications. Furthermore, the document defines and specifies electrical, mechanical, and physical rcquircmcnts of dry-type converter reactors used for voltagc-sourccd I-IVDC converters (VSC HVDC) that are located at the converter arms and loaded with dc and ac current. Test code is also defined and specifled. Converter reactors are usually built in dry-type air-core and air-cooled design. Thus, only this type ofconverter reactor design is considered in this standard.
In addition, appropriate technical background information, that will facilitate the use of this standard, is presented or idcntificd.
1.3 Word usage
The word sizull indicates mandatory requirements strictly to be followed in order to conform to the standard and from which no deviation is permitted (shall equals is required to).
The word should indicates that among several possibilities one is recommended as particularly suitable, without mentioning or excluding others; or that a certain course of action is preferred but not necessarily required (should equals is recommended that).
The word mm is used to indicate a course of action permissible within the limits of the standard (may equals is permitted to).
The word can is used for statements of possibility and capability, whether material, physical, or causal (can equals is able to).
