Scope
NB/T 42041-2014 is the English-translated version of 小水电机组安装技术规范.
NB/T 42041-2014 is the Chinese energy industry standard, recommended in status, that sets out how small hydropower generating units are installed.
It covers the units themselves, meaning the hydraulic turbine and the generator taken together, and their ancillary equipment, including the turbine inlet valve, the turbine governing system, the excitation system and the monitoring, protection and DC power supply systems.
Classified under K55 and under ICS 27.140, it addresses the installation work on site rather than the design of the machines. It is applied with a wide set of cited documents, among them GB/T 8564, GB 50150, GB 50171, DL/T 5161 and JB/T 8439. Issued on 15 October 2014, it has applied since 1 March 2015.
