1 Scope

GB/T 15145-2017 is the Chinese national standard on general specification for transmission line protection equipment, in the field of electrical engineering. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 31 July 2017 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 February 2018. Classification: ICS 29.240, CCS K45. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the transmission line relay protection device (hereinafter referred to as "device") technical requirements, test methods, inspection rules and standards Chi, packaging, transportation, storage and quality assurance deadlines and other requirements. This standard applies to 110kV and above neutral grounding system of AC transmission line relay protection devices, as such devices Development, design, manufacture, test, inspection and application of the basis.
