DL/T 437-2012 Translated English of Chinese Standard. (DLT437-2012, DL/T 437-2012): Technical guide of HVDC earth electrode systemhttps://www.chinesestandard.net, 2021 M10 2 - 21 páginas This Standard specifies the terminology terms and definitions of HVDC earth electrode system, and proposes technical conditions, test items and methods, and general technical principles of operation and maintenance. This Standard applies to the earth electrode system at both ends of the monopolar and bipolar HVDC transmission system; it does not apply to the converter grounding grid. |
